MELBOURNE, Australia -- Alex Michelsen produced the biggest win so far of his fledgling career to upset 2023 runner-up Stefanos Tsitsipas, the No. 11 seed, in the first round of the Australian Open on Monday.

The 20-year-old unseeded American overcame nerves on his serve in the fourth set before clinching a 7-5, 6-3, 2-6, 6-4 win over Tsitsipas, a 26-year-old from Greece who has a career-high No. 3 ranking and has reached two Grand Slam finals.

Joining Michelsen in the second round will be fellow American Frances Tiafoe, who required five sets to get past France's Arthur Rinderknech 7-6 (2), 6-3, 4-6, 6-7 (4), 6-3.

Tiafoe, the No. 17 seed and a former Australian Open quarterfinalist, vomited at the end of the fourth set before wrapping up the victory in 4 hours and 8 minutes. He advances to his fifth straight Australian Open second round.

Michelsen, who had never beaten anyone seeded higher than 32 at a Grand Slam, started playing tennis around age 3 and practiced most days as a kid with his mother, Sondra, a school teacher who played college tennis.

"Yeah, I'm sure she's watching right now," Michelsen told the crowd on John Cain Arena, one of the three main show courts at Melbourne Park. "Yeah, we hit a million balls from the baseline every day. We'd go like 30 minutes up the middle, then we go across each way for like an hour and a half.

"I mean, we would just go out there and she would never miss a ball -- she's incredible. But no chance I'd be here without her, so thanks, Mom. Love you."

The No. 42-ranked Michelsen reached the third round last year on his Australia debut before losing in the first rounds at Roland Garros and Wimbledon and in the second round at the US Open.

He became the second unseeded American man to defeat a top-11 seed in the opening round in Melbourne, joining Patrick McEnroe, who defeated Boris Becker in 1995.

Michelsen played with freedom against Tsitsipas, taking big swipes with his service returns -- including three in one game late in the fourth set that helped earn him a vital break.

He got a bit tense on serve, surrendering two hard-earned breaks in the fourth set, but stayed composed in the last game. He finished the match with eight aces and eight double faults, but hit 46 winners and had only 40 unforced errors.

"First of all, I was just trying to stay super composed out there. I knew it was going to be a battle in the end," he said. "[The serve] started to let me down a little bit in the fourth, but super happy. It's all about the mindset."

Tsitsipas also lost in the first round of last year's US Open.

"My whole role was to try to go deep into the Australian Open. I knew the first thing I had to consider was not play doubles," Tsitsipas said. "I guess karma hit me, I was not able to deliver or play the way I was hoping to. ... The whole purpose was just to save up on some energy and be fresher hopefully in the deeper draw of the tournament."

Saquon Barkley looked to be off to the races, headed for a last-minute touchdown that would have had no impact on the outcome of the Philadelphia Eagles' 22-10 win over the Green Bay Packers on Sunday but would've cashed a lot of tickets for the betting public.

More bets were placed on Barkley to score a touchdown against the Packers than were placed on any other player in Sunday's three NFL playoff games at multiple sportsbooks.

Barkley to score a touchdown was the third-most popular leg of all NFL parlays Sunday at ESPN BET, and he appeared destined for the end zone after breaking free on the Eagles' final drive.

With Philadelphia leading 22-10 with 1:09 to play, Barkley took a handoff over left tackle and burst through the Packers' defense and into the clear, before electing to slide down after picking up the first down.

Eagles quarterback Jalen Hurts took a knee on the last play to run out the final seconds and secure the win.

Barkley said after the game that it "wasn't tempting" to try for a touchdown.

"It's first down you win the game, so it's get the first down and get down," he said. "Don't matter."

Barkley, who was a -190 favorite to score a touchdown at ESPN BET, finished with 119 yards rushing and no touchdowns.

PHILADELPHIA -- Eagles wide receiver A.J. Brown was spotted reading a book on the sideline during the second half of Philadelphia's 22-10 wild-card-round win over the Green Bay Packers on Sunday, and that generated some questions.

What was the book? Why was he reading it during the game? Was it a sign of frustration because he had just one catch for 10 yards on three targets?

Brown answered them one by one after the victory.

The book is "Inner Excellence" by Jim Murphy, written to "train your mind for extraordinary performance and the best possible life." Brown said he brings the book to every game; this is just the first time cameras caught him reading it, he said. He has highlighted passages that he said help bring him a sense of peace. And no, he wasn't reading it because he was discontented.

"I wasn't frustrated at all. I figured that's what y'all probably thought," Brown said. "Why do you always think I be frustrated? Dang. I like to read."

Brown went on to social media to further explain why reading during games works for him.

"I use it to refocus and lock in despite what may transpire in the game good or bad," he wrote. "People tend to create controversy when they don't know the truth."

The workweek was not without its challenges. Brown was limited Wednesday and missed Thursday's practice as he managed a knee issue. He acknowledged he entered the game against the Packers "banged up" but spoke optimistically about the injury afterward, saying, "I definitely feel like I'm turning the corner. I came out of the game healthy."

With Eagles quarterback Jalen Hurts missing the past two games because of a concussion and both Brown and DeVonta Smith (back tightness) sidelined for parts of the week, the passing game struggled to get into rhythm against the Pack. At one point, Hurts went 90 minutes between completed passes. He managed only 39 yards on just 6-of-13 passing heading into the latter stages of the third quarter before going 3-of-3 for 61 yards on a scoring drive, which was capped by a stiff-arm-fueled 24-yard catch and run for a touchdown by tight end Dallas Goedert.

"I'm pretty sure he wishes he could get some plays back. I'm sure we all can say that," Brown said of Hurts. "But for the most part, he handled the game. He didn't have any turnovers. We got the win, most importantly."

The Eagles will host the divisional round of the playoffs next weekend. It's safe to say Brown will have a copy of the book at the ready.

"I've never seen him read [on the sideline]; I've seen the book in his hands," Hurts said. "Everybody has a different thing and finds their flow in different ways. That's how he chooses to do it."

TAMPA, Fla. -- Jayden Daniels ran for a critical first down to set up Zane Gonzalez's 37-yard field goal that clanged off the right upright and went through as time expired, and the Washington Commanders beat the Tampa Bay Buccaneers 23-20 in an NFC wild-card game Sunday night for the franchise's first playoff win in 6,945 days.

Daniels, playing with a bandage beneath his right eye after his face was bloodied, became the third rookie quarterback in three years to win a playoff game.

The Commanders (13-5) will face the No. 1 seed Detroit Lions (15-2) in the divisional round.

Baker Mayfield and the Buccaneers (10-8) missed several opportunities and the veteran quarterback committed a costly turnover in the fourth quarter. The Bucs couldn't get 1 yard on two tries from the Commanders' 12 and settled for a field goal to tie the score before Washington's winning drive.

"It just comes back to me, just timing it up correctly. First one all year that happened on, so, obviously timing of it not great being backed up," Mayfield said of the fumble. "Defense had just done a hell of a job getting us the ball. Another fourth-down stop and yeah, unfortunate, but that falls on me."

Daniels threw for 268 yards and two touchdowns, joining C.J. Stroud and Brock Purdy as rookie QBs to win playoff games in the past three seasons.

"It means a lot," Daniel said during his on-field, postgame interview on NBC. "Our fans are over there waiting for us. They've waited a long time for this feeling, so I'm just so happy for them."

Washington hadn't won in the postseason since beating the Buccaneers in Tampa Bay 17-10 in a wild-card game on Jan. 7, 2006.

"He came in humble, he does the work, and he has a lot of fun," Commanders linebacker Bobby Wagner said of Daniels during his interview on NBC. "It's fun to be here ... definitely because I'm playing with him."

The Buccaneers opened the season with a 37-20 victory at home against the Commanders in Daniels' first game. Daniels went on to have an outstanding season, was selected to the Pro Bowl and helped Washington improve from 4-13 to 12-5.

"You've got to give him credit, they made plays. I mean, he's been making them all year. You got to give him credit, they made some plays," Tampa Bay coach Todd Bowles said of Daniels and the Commanders. "We had our chances to make some plays that we didn't make, but it was a combination of both. They made plays and we didn't make the plays when we had the chance."

Now, Daniels has the Commanders headed to Detroit to face Jared Goff and the Lions' high-octane offense.

After Tampa Bay's defense held inside the 5 in the opening minute of the fourth quarter to preserve a 17-13 lead, Mayfield gave the Commanders the ball back when he fumbled an exchange on a handoff to Jalen McMillan. Washington recovered at the Buccaneers' 13. On fourth-and-2 from the 5, Daniels connected with Terry McLaurin in the back of the end zone for a 20-17 lead.

Mayfield drove the Buccaneers to a second-and-1 at the Commanders' 12 but they settled for a 32-yard field goal by Chase McLaughlin that tied it at 20-20 with 4:41 left.

The Buccaneers never got the ball back, thanks to Daniels, who calmly led his team downfield. With less than a minute left, he was hit behind the line of scrimmage but scrambled for 4 yards on third-and-2, allowing him to take a knee to set up Gonzalez's winning kick.

Commanders coach Dan Quinn previously passed up short field goals on fourth down twice and the offense failed to convert before McLaurin's scoring catch.

On fourth down from the Buccaneers' 4 less than a minute into the fourth quarter, Daniels threw incomplete. He was pressured and threw incomplete on fourth-and-2 from Tampa Bay's 20 on Washington's first possession of the game.

Mayfield tossed a 4-yard TD pass to Bucky Irving to give the Buccaneers a 17-13 lead in the third quarter. On the previous play, 350-pound defensive tackle Vita Vea was Mayfield's intended receiver, but the QB got sacked for a 2-yard loss.

Mayfield fired a 1-yard TD pass to Mike Evans to tie it at 10 late in the first half.

Gonzalez kicked a 22-yard field goal to give Washington a 13-10 lead on the opening drive of the second half. The Commanders had a first down at the 3 but Tampa Bay's defense held.

After Austin Ekeler ran 2 yards on fourth-and-1 from the Buccaneers' 23 late in the first quarter, the Commanders went ahead a few plays later to complete a 92-yard drive. Daniels, with his face bloodied, tossed a 10-yard TD pass to Dyami Brown for a 7-3 lead.

A holding call on cornerback Zyon McCollum negated a third-down sack by Yaya Diaby and allowed Washington to extend its next drive that ended with Gonzalez nailing a 50-yarder for a 10-3 lead.

McLaughlin kicked a 50-yard field goal on the opening drive. The Buccaneers were 9-1 when they scored first in the regular season.

TAMPA, Fla. -- The Washington Commanders continue to prove one thing this season: They're ahead of schedule. They also know how to win close games.

Washington, which won eight more games this season than a year ago, emerged victorious yet again with a dramatic finish. Zane Gonzalez hit a 37-yard field goal to beat Tampa Bay 23-20 in the wild-card round -- providing Washington with its first playoff win since the 2005 postseason.

It has become a habit this season for a team that loves talking about "winning moments," and coach Dan Quinn said he focused more on late-game situations in practice than he had at any point in his career.

The Commanders ended the regular season with five straight wins -- three occurred on the last play from scrimmage and a fourth ended with Washington stopping a 2-point conversion on the final play.

In Week 8, Washington beat Chicago on a 52-yard Hail Mary pass at the buzzer and, in Week 2, defeated the New York Giants a last-second field goal.

The Commanders, who went 4-13 last season, have won by paying attention to detail. Late-game success enabled them to post a 12-5 record in Quinn's first season. Quarterback Jayden Daniels was a huge key in Sunday's win, but the Washington defense allowed 284 yards, slowing the Bucs' high-powered offense.

Here are the most important things to know from Sunday night for both teams:

Washington Commanders

Pivotal play: For the fourth time in the game, Washington went for it on fourth down. This time it was from the Tampa 5-yard line with 9:46 left. The Commanders had failed on a fourth-and-goal from the 3, but this time Daniels connected with receiver Terry McLaurin for the touchdown and 20-17 lead. It was McLaurin's 11th red zone touchdown catch of the season; he had 11 in his first five years combined. The drive was set up by linebacker Bobby Wagner's fumble recovery at the Tampa 13.

QB breakdown: Daniels did not look like a rookie playing his first playoff game. He completed 24 of 35 passes for 268 yards and two touchdowns. He rushed for another 36 yards on 13 carries. He also made plays he could not make in the season-opening loss to Tampa because of one big change: He kept his eyes downfield when he scrambled. It resulted in key plays, such as a 9-yard completion to tight end Zach Ertz on a third-and-6 from the Commanders' own 12-yard line.

Troubling trend: Cornerback Marshon Lattimore has not played the way Washington hoped in his two games against big-time receivers since being acquired from New Orleans ahead of the trade deadline. He was flagged for three pass interference penalties versus Philadelphia's A.J. Brown on Dec. 22 and one against Mike Evans Sunday night. Evans got open against Lattimore, making him look like a player who had played in just two games since Oct. 27 because of left hamstring issues. -- John Keim

Tampa Bay Buccaneers

The Buccaneers should have gone for it while they had the chance.

They had the opportunity to tie or go for it on fourth-and-3 at the Washington 14-yard line with 4:45 to go and kicked a tying field goal to make it 20-20. ESPN Analytics disagreed with that decision, having their win probability at 46.1% (57.4% chance to convert) if going for it, whereas their win probability with a field goal was 43.6% with a 93.2% chance to make the field goal.

After the Bucs tied it up, Washington strung together chunk pass plays of 21, 18 and 8 yards while eating up valuable clock time, setting up the Commanders' 37-yard winning field goal.

Pivotal play: After a hard-fought goal-line stand at the Tampa Bay 3 that preserved the Bucs' 17-13 lead, Baker Mayfield fumbled a handoff that was recovered by Commanders linebacker Bobby Wagner at the Tampa Bay 13. With Josh Hayes stepping in for injured cornerback Jamel Dean, Jayden Daniels connected with Terry McLaurin on an in-route to retake the lead at 20-17 with 9:46 to go. It was the first time in six games that the Bucs had allowed a second-half touchdown.

Biggest hole in the game plan: The Bucs' defense could not get off the field. The Commanders were 8-of-15 on third down, none bigger than Daniels' keeper around the right side in the final minute. Their zone defense struggled against plays going across the field, including a 30-yard reception by Dyami Brown, and in-routes, such as Brown's 10-yard touchdown and 17- and 18-yard receptions by McLaurin. And then there were the penalties: They had seven for 65 yards.

Most surprising performance: Evans vs. Lattimore is typically a more tightly contested matchup, but this time it was all Evans. The Bucs' top receiver caught all five targets with Lattimore as the nearest defender for 73 yards and a touchdown. It was the second-highest receiving total Evans has had against Lattimore, behind a 115-yard performance in 2018. Evans had seven receptions for 92 yards on the night. -- Jenna Laine

At last some positive injury news with the rare sight of a fit and healthy Wales hooker.

Elliot Dee's timely return from a lengthy ankle problem will be welcomed by Gatland, who is without Dewi Lake, Ryan Elias, Liam Belcher and Efan Daniel.

"It was great to see him out there. He's led with a real competitive edge and has the mentality to play at this and the next level," said Dragons head coach Filo Tiatia.

Sam Parry, a try scorer for Ospreys on Saturday, is the most obvious selection on paper, but only if he can resolve his differences with Gatland after walking out of the Wales camp last summer.

"Parry is a great set-piece hooker and whatever has gone on between them, they've got put it aside for the best of the team, especially given the injuries," said Hook.

Elias may yet be picked, for the latter stages of the tournament, as well as Cardiff's Evan Lloyd, despite his wayward throwing in Perpignan.

Gatland also has concerns over a third tight-head behind Henry Thomas and Keiron Assiratti.

Archie Griffin, Harri O'Connor and Sam Wainwright are all out and Leon Brown has been forced to retire, so could the coach recall Six Nations winner Dillon Lewis, as he did for the summer tour?
