LONDON -- Arsenal came from behind to beat north London rivals Tottenham Hotspur 2-1 at Emirates Stadium on Wednesday and closed the gap on Premier League leaders Liverpool to four points.

Son Heung-Min gave Spurs a 25th-minute lead against the run of play after his shot from the edge of the box deflected off William Saliba and past Gunners goalkeeper David Raya. Arsenal responded 15 minutes later when Gabriel Magalhães tried to meet Declan Rice's corner at the back post, only for Radu Dragusin's header to hit Dominic Solanke and find a way past Antonin Kinsky.

Tottenham goalkeeper Kinsky, making his league debut after a 12.5m move from Sparta Prague, endured a shaky first half and was culpable in failing to stop Leandro Trossard's low drive from outside the box a minute before the break, which turned out to be the winner.

A tense second half followed in which Arsenal created the better chances before Spurs defender Pedro Porro hit the post deep into stoppage time, but Mikel Arteta's side secured a win which takes them above Nottingham Forest into second place. Leaders Liverpool, however, still have a game in hand: their rearranged Merseyside derby against Everton on Feb. 12. -- James Olley

Arsenal chip away at Liverpool's lead...

Liverpool's 1-1 draw at Nottingham Forest a day earlier will only have given Arsenal more motivation here, if any was required for the visit of their fierce local rivals. Last time Liverpool dropped points -- against Manchester United on Jan. 5 -- Arsenal had already been held at Brighton & Hove Albion.

This match week, however, they took full advantage.

Self-belief had wavered a little in these parts after successive cup defeats to Newcastle United and Manchester United and, while this was far from the complete performance, they got a precious victory, which turns up the pressure on Arne Slot's side ahead of the Reds' tricky trip to Brentford on Saturday. -- Olley

... yet striker doubts persist

Despite the result, Arsenal were once again not at their best in front of goal.

They ended with an expected goals figure of 1.70 -- significantly down on their games against Newcastle and United -- requiring an own goal from a set-piece and a goalkeeping mistake to beat Spurs. Arteta shuffled his forward line here, handing a rare start to Raheem Sterling -- just his third in the league since signing on loan from Chelsea last summer -- while Trossard occupied the left flank with Gabriel Martinelli dropped to the bench.

Judgements should not be overly critical on a night where Arsenal showed spirit and fight to get themselves over the line, but their overall play in the final third did little to silence longstanding concerns that they may need to sign another player to bolster their forward line this month. Kai Havertz endured another unconvincing night in goal, while Sterling was better without the ball than with it. The clamour to sign a striker this month would have grown exponentially had their failed to win here and while they avoided that fate, the conversation will undoubtedly continue.

Set-pieces came to the rescue for Arteta's side once more: Arsenal have scored four league goals from corners against Tottenham since the start of last season -- the most any team has netted against an opponent in this period. -- Olley

Kinsky's Premier League baptism of fire

It's been quite the introduction for Kinsky to Tottenham life. Having joined on Jan. 5, he'd already kept clean sheets for Spurs in their Carabao Cup semifinal against Liverpool and on Sunday in their FA Cup third round match at Tamworth. But on his Premier League debut, the North London derby was a different kind of challenge for Kinsky, and a proper acid test of his mentality and composure. He had Havertz constantly hustling every touch he took, ensuring he was forever rushed as he sought to play out from the back.

While his distribution was largely sound, he was caught twice by Havertz as he dawdled on the ball. While he did well on their constant bombardment of corners into his six-yard box, for Solanke's own-goal he was trapped by a teammate as he looked to punch clear. The Czechia under-21s star would have hoped to have got at least a glove on Trossard's strike in the 44th minute as it threaded through his out-stretched arms.

But to his credit, Kinsky stuck to his guns. In the second half he saved superbly off Martin Odegaard to keep Arsenal's lead at a single goal. He looks a shrewd signing by Spurs, and able competition for Guglielmo Vicario as their first-choice keeper continues his recovery from a fractured ankle, but this was a mixed performance from him. -- Tom Hamilton

Is Son still Spurs' main man?

As Tottenham searched in vain for an equaliser in the final throes of the match, their talismanic forward and club captain Son watched on from the bench. It was jarring to see him substituted in the 78th minute for Richarlison.

For so long Son has been irreplaceable at Spurs, and rightly so. He's a club legend, a wonderful player, and someone who can turn the balance of the match in a blink of an eye, but his substitution suggests he's no longer untouchable. It started so well for Son, as he opened the scoring for Spurs after 25 minutes with a deflected effort. It was his first Premier League goal since mid-December, when he scored in their 5-0 dismantling of Southampton.

For the rest of his time on the field, he was hovering on the halfway line, looking to counter, but Spurs' transitional play was let down by their midfield constantly coughing the ball up. He had just 24 touches of the ball -- his second lowest total in the league this season, just exceeding the 18 he managed in 33 minutes against AFC Bournemouth. Eventually his number was held up, and in his place Richarlison failed to make a dent on the left-flank as Spurs treaded the tight-rope of pushing for an equaliser while trying to nullify Arsenal's counter-attack.

Son's substitution means he has completed just one Premier League match for Spurs in their last eight -- on that occasion he played the full 90 as Tottenham fell 4-3 at home to Chelsea. -- Hamilton

Pressure on Postecoglou remains

It is difficult not to have a degree of sympathy with the injury problems Ange Postecoglou is contending with at Tottenham. Robbed of both first choice centre-backs, two left-backs and two goalkeepers, Spurs' patched up defence was always prone to looking vulnerable.

But this is a result that leaves Tottenham in 13th place after an 11th league defeat of the season. Only the three teams in the relegation zone -- Wolverhampton Wanderers (13), Leicester City (13) and Southampton (16) -- have lost more. Postecoglou has two cup competitions to fight for -- and the prospect of a Carabao Cup semifinal second leg next month against Liverpool, in which they hold a first-leg lead, should insulate him from any immediate danger, but there will surely soon come a point when the pressure will begin to build on the Australian.

They are now 14 points off fifth place -- which is likely to be enough to secure UEFA Champions League football -- and just eight points above the relegation zone. Results have to improve, even accounting for the mitigating factors. Like Arsenal, Spurs are also under pressure to act in the market, but for a completely different reason. -- Olley

Bill Belichick's first coaching staff at North Carolina continues to come together.

Longtime NFL special teams coach Mike Priefer and veteran SEC offensive line coach Will Friend are expected to finalize deals to join Belichick's staff, sources told ESPN on Wednesday.

After coaching for nearly a decade in college, Priefer moved to the NFL in 2002 and was a special teams coordinator from 2006 to 2022. He is noted in Cleveland Browns history as serving as the head coach in a January 2021 wild-card victory over the Pittsburgh Steelers, which is the franchise's only postseason win since the 1994 season. Priefer stepped in for Kevin Stefanski, who watched the game at home with COVID.

Priefer was the special teams coordinator for the Kansas City Chiefs (2006-08), Denver Broncos (2009-10), Minnesota Vikings (2011-18) and Browns (2019-22). He brings ties to the Naval Academy, something he shares with Belichick and his family. Priefer is a Navy graduate and served as a graduate assistant there.

Friend worked last season as Western Kentucky's offensive coordinator. He brings strong recruiting ties in the South, having worked at Georgia, Tennessee, Auburn and Mississippi State as the offensive line coach. He has also worked as the offensive coordinator at Colorado State and WKU.

Friend has a long history of developing linemen for the NFL.

With Priefer and Friend, there are six known members of Belichick's staff, which includes longtime NFL coach Freddie Kitchens as the offensive coordinator and veteran NFL coach Stephen Belichick as the defensive coordinator.

The hires line up the objectives of Belichick, who has stressed that he wants to run the Tar Heels like a NFL program.

Before taking the UNC job, Belichick told ESPN's Pat McAfee that if he were to run a college program, it would be a "pipeline to the NFL for the players that had the ability to play in the NFL."

He added: "It would be a professional program. Training, nutrition, scheme, coaching, techniques that would transfer to the NFL. It would be an NFL program at a college level and an education that would get the players ready for their career after football."

EL SEGUNO, Calif. -- Los Angeles Chargers coach Jim Harbaugh said Wednesday that he will have a cardiac ablation this offseason and hip replacement surgery.

Harbaugh, 61, briefly left the Chargers' Week 6 game against the Denver Broncos after a flare-up with atrial flutter, a type of arrhythmia that causes the heart to beat at an abnormally high rate. Harbaugh wore a heart monitor for two weeks during the season.

Harbaugh went to the locker room, where paramedics treated him. He had an electrocardiogram scan and, eventually, they got his heart back to a normal rhythm. Harbaugh returned in the first quarter and coached the remainder of the game. Defensive coordinator Jesse Minter was the interim head coach while Harbaugh was out.

In 2012, Harbaugh had his last flare-up. It came when he was coaching the San Francisco 49ers in a game against the Chicago Bears on "Monday Night Football," when he felt an irregular heartbeat but finished coaching the game and saw doctors afterward.

As for his hip replacement, Harbaugh walks with a significant limp now because of his hip, which will be corrected with the surgery.

Harbaugh has said previously that he wouldn't consider retiring because of his health issues.

"It would take my heart stopping for me not to be out there on the sideline," Harbaugh said in October.

The Ravens' surprising waiver claim for journeyman Diontae Johnson could result in an additional draft pick for Baltimore.

Johnson, who was waived by Baltimore earlier this season, was claimed by the Ravens one day after the wide receiver was waived by the Houston Texans, it was announced Wednesday.

Johnson won't officially move to the Ravens until Feb. 10 -- the day after the Super Bowl. He qualifies as an unrestricted free agent. By claiming him, the Ravens will have a chance at earning a compensatory selection for the 2026 draft depending on the contract Johnson signs in free agency.

The Ravens have been the best in the NFL in accumulating compensatory picks, earning a league-high 56 of them since the system began in 1994. Baltimore has used comp picks to select the likes of fullback Kyle Juszczyk, punter Sam Koch and tight end Isaiah Likely.

Johnson was waived by the Texans on Tuesday, and sources told ESPN's DJ Bien-Aime that Johnson had asked for his release. The receiver was visibly upset in the locker room after the Texans' wind-card playoff victory against the Chargers, sitting fully dressed at his locker and staring in frustration because of a lack of playing time and targets.

"Unfortunately, with Diontae, it didn't work out," Texans coach DeMeco Ryans said Tuesday. "We're on to the Chiefs."

Johnson had three catches for 24 yards in two games with Houston after the Texans claimed Johnson off waivers from the Ravens on Dec. 23. Baltimore had moved on from the receiver after he refused to enter a game against the Philadelphia Eagles on Dec. 1.

Before the Ravens waived Johnson, they suspended him one game for his refusal to play against the Eagles. Baltimore had acquired him in a trade with the Carolina Panthers on Oct. 29, but he played only 39 snaps for the team, catching one pass for 6 yards.

The Panthers acquired Johnson from the Pittsburgh Steelers before the season. He had 30 catches for 257 yards and three touchdowns for Carolina when he left for the Ravens.

The Steelers drafted Johnson in the third round of the 2019 draft, and he had 391 catches for 4,363 yards and 25 touchdowns in Pittsburgh. He earned a Pro Bowl selection in 2021 with his lone 1,000-yard season and a career-high eight touchdown receptions in quarterback Ben Roethlisberger's final year.

Oklahoma City Thunder center Isaiah Hartenstein will miss Thursday's matchup of the two teams with the NBA's best records because of a left soleus strain, the team announced.

According to the Thunder, Hartenstein suffered the injury during Tuesday's win over the Philadelphia 76ers and will be reevaluated in approximately one week.

The 33-6 Thunder face the 34-5 Cleveland Cavaliers on Thursday in Oklahoma City, a rematch of the Cavaliers' Dec. 8 home win that snapped the Thunder's 15-game winning streak.

It will be the second stretch this season that the Thunder do not have either of their 7-footers. Oklahoma City went 3-2 during the span between Chet Holmgren suffering a fractured pelvis and Hartenstein making his season debut, which was delayed by a fractured left hand.

Holmgren, who was injured in the first half of Oklahoma City's Nov. 10 loss to the Golden State Warriors, has begun doing simple basketball activities such as spot shooting as he gradually ramps up to his return.

Hartenstein, who signed a three-year, $87 million contract last summer in free agency to join the Thunder, is averaging career highs of 11.8 points, 12.2 rebounds, 4.1 assists and 1.3 blocks.

Oklahoma City has a 22-2 record when Hartenstein plays.

The Charlotte Hornets are trading center Nick Richards and a second-round draft pick to the Phoenix Suns for forward Josh Okogie and three second-round picks, sources told ESPN.

The Hornets are sending a 2025 Denver second-rounder to Phoenix, which trades a 2026 Nuggets second-rounder and 2031 second-rounders (Denver, Phoenix) to Charlotte, sources said.

The Suns, who rank last in the NBA in points from their starting center, land much-needed help at the position with the 7-foot Richards, who is averaging 8.9 points and 7.5 rebounds in 21 games this season, his fifth with the Hornets.

Richards has been even more productive in his nine starts this season, averaging 11.3 points, 10.2 rebounds and 1.7 blocks in those contests. He's shot 65% from the field over the last four seasons, fifth-best in the NBA during that span (min. 800 attempts), according to ESPN Research.

The Hornets have accumulated significant draft capital over the last year, acquiring two first-round picks and eight second-round picks in trades since January 2024. They'll also receive a look at a defensive-minded wing in Okogie, who, like Richards, has a team-friendly non-guarantee for the 2025-26 season.

Richards is expected to compete to become the starter at center for the Suns, who have primarily played Mason Plumlee and rookie Oso Ighodaro in recent weeks. Veteran center Jusuf Nurkic is currently sidelined due to the flu, but was moved to the bench for back-to-back games on Jan. 6-7 before being taken out of Phoenix's rotation completely.

Richards, coincidentally, played his last two games for the Hornets against the Suns. He posted 15 points, 12 rebounds and three blocks in 25 minutes in the Hornets' 115-104 win over the Suns on Jan. 7 and then had four points, five rebounds and two steals in 18 minutes in a loss Sunday.

PHOENIX -- Even though it had been nearly three weeks since ace right-hander Corbin Burnes had agreed with the Arizona Diamondbacks on a $210 million, six-year deal, it was still a little stunning to see him in the team's jersey at Chase Field on Wednesday.

The D-backs usually aren't among baseball's big spenders.

For Arizona owner Ken Kendrick, the four-time All-Star and 2021 NL Cy Young Award winner was a worthy investment. A slight hometown discount might have been a factor, too.

"We have the potential to be a championship team," Kendrick said. "Our job is to try and do everything we can to put the best team on the field possible that we can afford. We're stretching the budget. It won't be the last time."

The move keeps the Diamondbacks competitive in a loaded NL West that includes the free-spending Los Angeles Dodgers - who won last year's World Series - and the San Diego Padres and San Francisco Giants. Arizona has reason to be confident it can be successful after making it all the way to the World Series in 2023.

The D-backs won 89 games last season but missed the postseason after losing a tiebreaker to the New York Mets. Arizona had a payroll of roughly $143 million opening-day payroll last season, which ranked in the middle of MLB.

"We're looking to push forward, to put the best team possible on the field this year and beyond," Arizona general manager Mike Hazen said. "There's no better way to do that than to add a No. 1 starting pitcher to the top of your rotation.

"We know that's what wins in the postseason and we know that's what gets you to the postseason."

The 30-year-old Burnes - who is originally from California - moved to Arizona in 2018 when he played for the Milwaukee Brewers, partially so he could be close to the Brewers' spring training facility. He and his family liked the area so much they stayed, and it was a big factor in his decision to sign with the Diamondbacks.

Burnes played his first six seasons with the Brewers before his one and only season with the Baltimore Orioles in 2024. He had plenty of success, finishing 15-9 with a 2.92 ERA.

But the franchise's East Coast location was never a great fit for his family life. The pitcher would constantly fly back home to Arizona in between starts and he nearly missed the birth of his twins in June because of plane trouble.

Now he'll spend most of the year near home.

"When we heard this could be an opportunity, we got really excited," Burnes said. "This is something you dream about - what happens if the Diamondbacks call? We had to take it. We were fortunate they were interested."

The righty joins a starting rotation that could be one of the best in baseball. The D-backs bring back All-Star Zac Gallen, Merrill Kelly, Eduardo Rodriguez and Brandon Pfaadt, who have all enjoyed big league success.

Burnes said he realized the D-backs were one of the game's up-and-coming teams in 2023. He pitched well against Arizona early in the year but was knocked around later in the season as the team's young core improved. Manager Torey Lovullo focused on speed, defense and pitching, putting pressure on opposing teams with their aggressive demeanor.

"They're playing a different style of baseball and I think we're starting to see that around the league," Burnes said. "But to me, the Diamondbacks were the first team to do that. They've drafted well, developed well. I'm happy to be a part of it."

The D-backs hope the Burnes deal works out better than many of their recent forays into the free agent pitching market.

Lefty Madison Bumgarner signed an $85 million, five-year deal before the 2020 season but lasted just 3 1/2 disappointing seasons before getting released in 2023. Last year's big money deals for Rodriguez and Jordan Montgomery were also duds, with both pitchers battling ineffectiveness, injuries or both.

But Hazen wasn't scared to dive back into the free-agent pitcher market, especially when Burnes was an option.

"You might as well go do another job if we're going to be scared about bringing in a guy of this caliber," Hazen said.

NEW YORK -- Elian Peña, a shortstop from the Dominican Republic who turned 17 in October, agreed to a $5 million bonus with the New York Mets on Wednesday that was the largest amount on the first day of the 2025 international signing period.

Peña was rated the No. 3 prospect in the international class for this year by MLB.com behind Japanese pitcher Roki Sasaki, who must agree to a deal by Jan. 23, and Dominican shortstop Josuar De Jesus Gonzalez, who agreed with the San Francisco Giants to $2,997,500.

The Los Angeles Dodgers, San Diego Padres and Toronto Blue Jays, all hoping to sign Sasaki, did not finalize any contracts with bonuses of more than $10,000, which count against their signing bonus pools. Just half of the 30 teams finalized deals of more than $10,000 in the opening hours of the signing period.

Dominican outfielder Cris Rodriguez, ranked fourth, signed with the Detroit Tigers for $3,197,500, and Andrew Salas, a shortstop and outfielder ranked fifth, signed with the Miami Marlins for $3.7 million. Salas was born in the U.S. and moved to Venezuela.

Hoping to become a two-way player just like Shohei Ohtani, 18-year-old Shotaro Morii made the rare decision to bypass Japanese professional baseball entirely and agreed with the Athletics at $1,510,500.

Other agreements included Dominican infielder Johan De Los Santos and the Pittsburgh Pirates ($2.25 million), Venezuelan catcher Gabriel Davalillo and the Los Angeles Angels ($2 million), Venezuelan infielder Brayan Cortesia and the Washington Nationals ($1.92 million), Dominican infielder Darell Morel and Pittsburgh ($1,778,600), Venezuelan infielder Leon Santiago and the Minnesota Twins ($1,697,500), Dominican outfielder Maykel Coret and the Tampa Bay Rays ($1.6 million), Venezuelan outfielder Breyson Guedez and the Athletics ($1.5 million), Dominican outfielder Elian De La Cruz and the Arizona Diamondbacks ($1.1 million), Dominican shortstop Christopher Acosta and the Milwaukee Brewers ($1.1 million), Dominican infielder Raymer Medina and Tampa Bay ($1.1 million), Venezuelan catcher Daniel Hernandez and Washington ($1.1 million) and Dominican infielder Warel Solano and Tampa Bay ($1.05 million).

Players born from Sept. 1, 2007, through Aug. 31, 2008, are eligible to sign during this year's period, which ends Dec. 15. Teams have signing bonus pools ranging from about $5.1 million to $7.6 million; signing bonuses of $10,000 and under don't count against a team's cap.

The victory also meant the Serb became the first man over the age of 30 to reach 150 Grand Slam singles wins.

Djokovic can make further history still in Melbourne - win the title and he would claim a 25th major, moving him clear of Australia's Margaret Court as the sole leader of all-time Grand Slam singles titles.

The seventh seed, who has three-time Grand Slam champion Andy Murray in his coaching box, will face Czech 26th seed Tomas Machac in the third round.

Norwegian sixth seed Casper Ruud became the biggest casualty in the men's draw, losing 6-2 3-6 6-1 6-4 to 19-year-old Czech Jakub Mensik.

World number 48 Mensik and Joao Fonseca, the 18-year-old Brazilian qualifier who stunned ninth seed Andrey Rublev on Tuesday, are the first teenagers to beat top-10 opponents at the same Grand Slam since Djokovic and Murray at Wimbledon in 2006.

Meanwhile, German second seed Alexander Zverev claimed an assured 6-1 6-4 6-1 victory over Spain's Pedro Martinez to set up a third-round meeting with Britain's Jacob Fearnley.

Britain's Harriet Dart said the atmosphere during her Australian Open second-round defeat was "like a football match" and called for greater "respect" from fans.

Lucky loser Dart, who only discovered she had a place in this year's main draw one hour before her opening match on Monday, took the first set against Croatia's 18th seed Donna Vekic but was beaten 4-6 6-0 6-2.

Dart's issue with the court 14 crowd came on a day when rowdy supporter behaviour fell under the spotlight amid other incidents at Melbourne Park.

"I felt like I was at a football match. Obviously it's great to have lots of people there watching and everything but I also think there has to be respect towards both players," said Dart, 28.

"I think a few people were about to be kicked out. I can only really compare it to the Billie Jean King Cup and I don't even think I've had it be like that before.

"I think [the umpire] did as best as she could - maybe there should be a stricter policy in terms of if people are doing something, if they do it more than once they are out, but I don't make those rules."

Dart had struck the first blow in the deciding set before world number 19 Vekic won five straight games to complete her victory.

Elsewhere, the chair umpire had to make several appeals for respect towards the players during Jack Draper's match against Australian Thanasi Kokkinakis on John Cain Arena.

The home crowd attempted to unsettle Draper throughout the four-and-a-half hour contest, but the British number one said the "electric atmosphere" gave him energy and he responded by cupping his ear to the crowd on several occasions.

Canadian Felix Auger-Aliassime's match against Spaniard Alejandro Davidovich Fokina was moved from court eight because the players complained about the noise coming from neighbouring courts.

Boisterous French crowds gathered to watch Arthur Cazaux against Britain's Jacob Fearnley on court six, which has a bar, and on court three, where Ugo Humbert was facing Lebanon's Hady Habib.

"I actually didn't really look at the court before I went on, so when I saw the bar I was thinking it's going to be a pretty rowdy atmosphere," said Fearnley.

"I blocked it out as much as I could. Obviously there was some supporters who were extremely drunk, but it was a great atmosphere, amazing atmosphere."
