Boston Red Sox second baseman Dustin Pedroia said he is "not sure" whether he will play baseball again because of his chronically injured left knee.

Pedroia, 35, discussed his injury at Fenway Park on Monday, shortly after the Red Sox transferred him to the 60-day injured list.

Flanked by manager Alex Cora and president of baseball operations Dave Dombrowski, Pedroia said he will shut down his recovery indefinitely in order to ponder his future.

"(I am) at a point right now where I need some time," he said. "That's what my status is. ... Right now I know I need a break from the everyday stresses I've been dealing with."

Dombrowski referred to Pedroia as a "Boston legend" and said there is no timetable associated with his return.

Pedroia acknowledged that "walking is tough" for him on some days but said he does not plan to undergo another knee surgery.

Pedroia said "time will give me the right answer if my knee can do this."

The 2008 AL MVP had surgery on Oct. 25, 2017, and played in just three games last season. This year, he's played in only six games, getting two singles in 20 at-bats.

Pedroia re-aggravated his left knee in a game at Yankee Stadium on April 17 and was put on the 10-day IL with left knee irritation.

He has started and stopped rehab assignments a few times before he removed himself from a game at Double-A Portland last Friday due to soreness.

Indians manager Terry Francona, who was with the Red Sox from 2004-11 and won a World Series titles with Pedroia in 2007, talked with the second baseman earlier Monday. Cleveland is in Boston for a three-game series.

"He came over this morning for about a half hour," Francona said. "I think he's in a pretty good place. I think, I don't want to speak for him, but I think he knows he emptied his tank. He didn't leave any stone unturned. He probably gave more than he should, and his body is feeling it now. I don't think he has any regrets -- nor should he."

Pedroia said the time away will help him think about his future.

"I'm going to go home for a little bit to be with my family, kind of get away for a little bit and then we'll figure it out from there," he said.

He did say he'd be there when the team needs him -- via video chat.

"You can always FaceTime," Cora said, smiling.

"I FaceTime a lot," Pedroia said. "In our hitters' meetings when I was away last year."

Pedroia's knee troubles began in April 2017, when then-Orioles star Manny Machado took out Pedroia with a hard slide at second base.

Pedroia has a $15 million salary this year and is owed $13 million in 2020 and $12 million in 2021, with $2.5 million a year deferred without interest.

Bill Buckner, the longtime major leaguer whose error in the 1986 World Series for years lived in Red Sox infamy, died Monday. He was 69.

"After battling the disease of Lewy Body Dementia, Bill Buckner passed away early the morning of May 27th surrounded by his family," his family said in a statement. "Bill fought with courage and grit as he did all things in life. Our hearts are broken but we are at peace knowing he is in the arms of his Lord and Savior Jesus Christ."

Buckner played 22 seasons in the majors, was an All-Star once and won a batting title in 1980. But it was a ball that went through his legs at Shea Stadium on a cool Oct. 25 night in 1986 that made for one of baseball's most shocking moments.

Boston, looking for its first World Series title since 1918, carried a 5-3 lead into the bottom of the 10th inning of Game 6 against the Mets. New York tied it with two runs, then brought Mookie Wilson to the plate.

Wilson worked a 3-2 count off reliever Bob Stanley, and then, with a runner on second base, bounced a slow roller up the first-base line on the 10th pitch of the at-bat. Buckner ranged to his left, went down to snag the ball behind the bag and watched it roll through his legs and into right field. Ray Knight scored to give the Mets a 6-5 can-you-believe-it win. They took Game 7, too, a gut punch to a Red Sox team a strike away from a long-awaited title just 48 hours earlier.

"We had developed a friendship that lasted well over 30 years. I felt badly for some of the things he went through. Bill was a great, great baseball player whose legacy should not be defined by one play," Wilson said Monday in a statement released by the Mets.

Buckner's Red Sox teammates said he wasn't to blame, noting Boston wouldn't even have been in the World Series without his efforts that season.

"No one played harder than Bill. No one prepared themselves as well as Bill Buckner did, and no one wanted to win as much as Bill Buckner," right fielder Dwight Evans later said.

But many in Red Sox Nation didn't see it that way.

"When that ball went through Bill Buckner's legs, hundreds of thousands of people did not just view that as an error, they viewed that as something he had done to them personally," longtime Boston Globe columnist Bob Ryan once said.

That single moment ended up defining Buckner's career, and even followed him after it.

When he retired in 1990, he and his family remained in Massachusetts. But the taunts and criticism from fans and media remained, forcing them to move to Idaho, where Buckner, an avid outdoorsman, bought a ranch.

When the Red Sox invited him to take part in a ceremony at Fenway Park honoring the 20-year anniversary of the 1986 team, Buckner declined.

But time heals most wounds, and though it took years, the relationship between Buckner and Boston fans eventually warmed.

The first step came in 2004, when the Red Sox finally ended the "Curse of the Bambino" by sweeping the Cardinals in the World Series. For fans, it was a chance to forget about the past and celebrate the present.

The next step came four years later in the Red Sox's 2008 home opener. That previous October, the team had won its second World Series title in four years, and on that April day, they were celebrating it with past and present Boston sports greats. One of them there: Bill Buckner.

From out under a massive American flag draped over the Green Monster, Buckner was introduced to the crowd and walked slowly to the mound amid a standing ovation that lasted nearly two minutes. With tears in his eyes, the left-hander delivered the ceremonial first pitch, a strike to former teammate Evans as the Fenway faithful roared.

"I really had to forgive, not the fans of Boston, per se, but I would have to say in my heart I had to forgive the media," Buckner said of why he decided to return to Fenway. "For what they put me and my family through. So, you know, I've done that and I'm over that."

Buckner, a baseball and football star growing up in Napa, California, was a second-round draft pick of the Dodgers in 1968, going one round after Los Angeles took Bobby Valentine. Buckner made his major league debut as a 19-year-old in 1969, beginning the first of what turned out to be eight seasons with the Dodgers.

Valentine tweeted that he will miss his former teammate.

As I clear my head and hold back the tears I know I will always remember Billy Buck as a great hitter and a better friend. He deserved better. Thank god for his family. I ll miss u Buck!

The Dodgers tweeted "our thoughts and prayers are with the Buckner family."

Buckner was traded to the Cubs in 1977 and enjoyed some of his best seasons in Chicago. He won the NL batting title in 1980, hitting .324. A year later, he was named to his only All-Star team and finished 10th in NL MVP voting. The Cubs dealt Buckner to the Red Sox in May 1984.

"We are deeply saddened by the passing of Bill Buckner, a great ballplayer and beloved member of the Cubs family," Cubs executive chairman Tom Ricketts said in a statement, adding that "after his playing days, Bill served as a valued member of our player development staff and was a fan favorite during his appearances at our Cubs conventions."

In all, Buckner spent 22 seasons in the big leagues, playing first base or the outfield for five teams, including the Red Sox twice; they signed him as a free agent in 1990, but he struggled at the plate in his second stint there and was released before officially retiring. He finished his career with 2,715 hits, 1,208 RBIs, 1,077 runs scored and 174 home runs.

After his playing career, Buckner remained in baseball as a coach, including a stint as the White Sox hitting coach in 1996 and '97, and a return to Massachusetts in 2011 as manager of the independent league Brockton Rox.

He is survived by his wife, Jody, and three children, Brittany, Christen and Bobby, who played baseball collegiately.

PARIS -- Rafael Nadal made light work of qualifier Yannick Hanfmann on Monday, winning 6-2, 6-1, 6-3 to advance to the second round of the French Open.

The 11-time champion at Roland Garros saved four break points in his first service game on Court Philippe Chatrier but was never troubled again by the 184th-ranked German, who was playing for the first time in the French Open main draw.

Nadal later praised the refurbished showcase court where he won his 11 French titles, calling it "very beautiful.''

Frances Tiafoe, at No. 32 the only American seeded in the men's draw, lost 6-2, 4-6, 6-3, 3-6, 6-0 to Filip Krajinovic of Serbia.

After throwing up twice on the court, Tiafoe said he was "very depleted'' for the fifth set. He said he didn't think he had food poisoning because he felt fine before the match.

"Throwing up during the match isn't something that normally happens to me ... I threw up again when I went to the locker room after the third set. The fifth-set result obviously came to that because (I) was obviously very depleted and had nothing really in me. It was tough to end like that," he said.

Tiafoe was coming off his best Grand Slam showing, a quarterfinal run at the Australian Open.

In another instance of an American losing to a Serbian in five sets, Denis Kudla was beaten 6-0, 6-7 (7), 5-7, 6-3, 6-4 by Miomir Kecmanovic.

Also, 12th-seeded Daniil Medvedev wasted a two-set lead in a 4-6, 4-6, 6-3, 6-2, 7-5 loss to Pierre-Hugues Herbert of France.

Two-time Wimbledon champion Petra Kvitova has withdrawn from the French Open with an arm injury but hopes to be fit for the All England Club.

The Czech sixth seed, 29, was due to face Romanian world number 84 Sorana Cirstea in the first round on Monday.

"I've had pain in my left forearm for a few weeks and last night an MRI confirmed a grade-two tear," she said.

She hopes to play at Wimbledon, which starts on 1 July, and is due to feature in June's Birmingham grass-court event.

"They [doctors] said for now two to three weeks off, which means no tennis of course, because it's my left forearm," she added.

"I'm going to do some fitness and everything I can do to prepare my body for grass.

"Of course I'm staying positive for the grass season."

Kvitova, who won Wimbledon in 2011 and 2014, has been replaced in the Roland Garros draw by lucky loser Kaja Juvan of Slovenia.

"I'm truly sad not to be able to play here this year," the world number six said. "It is a really tough decision to make."

Kvitova retired with a calf injury from this month's Italian Open in the third set against Greek Maria Sakkari.

But she was nevertheless among the favourites for the title at Roland Garros as one of this year's in-form players.

She has won two WTA titles in 2019 - at Stuttgart and Sydney - and was also runner-up at January's Australian Open and the Dubai Championships in February.

Former Australian Open champion Caroline Wozniacki says she "ran out of steam" in a surprise first-round defeat by Russian world number 68 Veronika Kudermetova at the French Open.

The Danish 13th seed lost 0-6 6-3 6-3 despite winning the first seven games and said her opponent had "got lucky".

"It's definitely frustrating," the 28-year-old former world number one said.

"It hasn't been a great year for me so far, so I'm going to work hard and try and turn it around."

Wozniacki, who wore strapping on her left calf, won 62% of the total points in the opening set but crumbled in the second and was broken three times.

She went 3-0 behind in the decider before losing a first-round match in Paris for only the third time since 2007.

"I think she got very lucky at the start of the second set and took advantage of the opportunities she got," Wozniacki added.

"I ran out of steam in the end and made some unforced errors that I don't usually do.

"She had a few net cords and good shots on some of the important points at the start of the second set."

The Dane, a two-time quarter-finalist at Roland Garros, withdrew from her first-round match against American Danielle Collins at the Italian Open earlier this month because of a calf injury.

It was the second successive tournament Wozniacki retired early from after she pulled out of her opening match at the Madrid Open with a back injury.

She had won just four matches on clay before her meeting in Paris with Kudermetova, who was playing in only her second Grand Slam main draw.

"I hadn't really been able to play or practise for some weeks, then played my first points a couple of days ago and went from there basically," Wozniacki said.

"But my calf now feels good, so that's a positive. I have to try and stay positive and obviously it's not as easy to stay positive when things aren't going your way."

Wozniacki's exit comes after Czech sixth seed and Australian Open finalist Petra Kvitova withdrew on Monday with an arm injury, while Wimbledon champion Angelique Kerber suffered a shock 6-4 6-2 defeat to world number 81 Anastasia Potapova on Sunday.

Kudermetova will now face Kazakh world number 99 Zarina Diyas or France's Audrey Albie, ranked 289th, in the second round.

Elsewhere, Dutch fourth seed Kiki Bertens comfortably defeated French world number 66 Pauline Parmentier 6-3 6-4 on Suzanne-Lenglen.

And Australian Open quarter-finalist Ashleigh Barty, seeded eighth, beat American world number 72 Jessica Pegula 6-3 6-3.
