The No. 2 seed, Murray reached the quarterfinals for the 22nd time in his past 23 Grand Slam tournaments.During the changeover right before the last game, it suddenly began to rain, and play was delayed only slightly before the shower passed. The new retractable roof at Arthur Ashe Stadium was not closed.I played extremely well. Tactically, played a good match, Murray said. And I served very well when I was behind in the games. Got a lot of free points with my serve, and that was important.He was credited with one serve at 141 mph, which he said would be the first of his career that topped 140.I served one at 145 in San Jose, but the next day, Murray said with a smile, they recalibrated the gun because it was completely wrong.The 2012 champion at Flushing Meadows will face No. 6 seed Kei Nishikori in the quarterfinals Wednesday.

A new venue to be built to replace it.Karlovic, 37, was the oldest man to reach a Grand Slam round of 16 since Jimmy Connors at the 1991 U.S. Open. At 6-foot-11, Karlovic set a tournament record with 61 aces in a five-set win in the first round.Unlike Murray and Nishikori, two-time major champion Stan Wawrinka had a tougher road to the quarterfinals.Wawrinka blew a lead and smashed a racket, but he eventually pulled out a four-set victory to reach a fourth straight US Open quarterfinal.After saving a match point in a five-set win in his last outing, Wawrinka was cruising against 63rd-ranked Illya Marchenko, who was playing in his first Grand Slam round of 16. Serving for the match in the third set, the third-seeded Wawrinka was broken and then lost a tiebreaker.After going down a break early in the fourth set, Wawrinka took his frustrations out on his racket. He proceeded to win the next four games to regain control on the way to a 6-4, 6-1, 6-7 (5), 6-3 victory Monday.Marchenko had dropped the first set of his third-round match against 14th-seeded Nick Kyrgios but won the next two as the Australian struggled with a hip injury that eventually forced him to retire.Wawrinka next faces 2009 US Open champ Juan Martin del Potro, who beat Wawrinka at Wimbledon this year.Del Potro is back in the quarterfinals after Dominic Thiem retired in the second set of their match.The eighth-seeded Thiem took a medical timeout to have trainers look at his right knee after the sets fifth game. He returned to the court for one point before deciding he couldnt go on.Thiem said his knee started hurting three days earlier, and he speculated it was the indirect result of blisters on his feet -- he needed to alter his gait to compensate. Late in the first set Monday, it started getting worse. He didnt want to take any risks with a knee injury and planned to get an MRI.I couldnt bend it too much the last three days, he said. So I was all the time a little bit handicapped.Del Potro had won the first set 6-3 and was up a break in the second.Thiem, who turned 23 on Saturday, has had a breakthrough year, reaching the French Open semifinals and cracking the top 10. But the long season was starting to wear on his body.Del Potro knows all about that. He missed the tournament the past two years after surgeries on his left wrist. But his stunning run to the Olympic silver medal signaled that he is a contender again.Del Potro got a huge break Monday when he spent only 72 minutes on court. He has played just 10-plus sets through four rounds, but still expects to be the underdog.[Wawrinka] will be the favorite to win in that match, del Potro insisted, before adding: But anything can happen in this event for me. I got the power from the crowd in every match.At No. 142, del Potro is the lowest-ranked US Open quarterfinalist since Jimmy Connors in 1991.Information from The Associated Press was used in this report.

SAN ANTONIO -- Former Spurs forward Tim Duncan made an appearance at the teams training camp workout Wednesday, just two days after coach Gregg Popovich joked he would fine the future Hall of Famer $2,500 for each day he was absent.But even with Duncans surprise appearance, his role within the organization remains a work in progress.When I got done arguing with him about why hes been fined for not showing up the last few days, we got that out of the way first. Most people under contract are required to show up for their jobs, Popovich said jokingly. He said he didnt have a contract. But I told him I thought we had a verbal contract, and I thought that was just as good as written. Were having a tough time right now, the two of us, trying to get him straight. Hes always been tough to manage, especially so now that hes retired.One of the cornerstones of San Antonios five NBA championships, Duncan announced his retirement in July after 19 seasons with the team. He served as a spectator as the club scrimmaged Wednesday and could be seen conversing with former teammates as they took part in an after-practice shootaround.Popovich mentioned Monday that Duncan would remain involved with the team and joked that he would be the coach of whatever he feels like. Popovich said there is no room for Duncan on the bench during game situations and joked that hes too smart for that anyway.The coach was unsure whether Duncan would take part in some road trips, saying the organization just want[s] to let it kind of morph into its own sort of thing.Spurs general manager R.C. Buford said the plan is to let Duncans role evolve. Duncan lives fairly close to the teams practice facilities, and his car customization business, BlackJack Speed Shop, is less than five minutes from the clubs practice site.ddddddddddddLike Popovich, Buford said Duncans role will be whatever he decides it to be. But first the club would like Duncan to adjust to life after basketball, while finding the niche in which hes most comfortable.I think hes learning about life after playing, Buford said. And he can impact us in so many ways. I think we need to sit back and get a better understanding of how he feels like he wants to fit in and what works for his family. Then well figure it out from there. But the gym feels better when hes in it.New acquisition Dewayne Dedmon agreed.Oh, definitely, Dedmon said. He was one of the best to ever do it. So its always a plus when he comes around.Dedmon said he has already received some coaching tips from Duncan, who told the new Spurs center that I need to talk more, communicate more on defense. Ill be doing that next time. He says a couple of words to you, lets you know what you need to do.Given the fact the Spurs brought in 12 new players among the 20 on the roster, several of the new acquisitions plan to absorb as much information as possible about the clubs culture from Duncan, who played a significant role in creating it.He has as much knowledge about being in the NBA as anybody who has ever played the game, said David Lee, an 11-year veteran and two-time All-Star who joined the Spurs in August after spending the 2015-16 season with the Dallas Mavericks. He has a great feel for the game, perhaps the best of all time. Thats someone Im definitely going to listen to whenever he has something to say. ' ' '
