RIO DE JANEIRO -- Juan Martin del Potro sobbed into Novak Djokovics shoulder, the two opponents locked in a long embrace at the net.Djokovic would walk off the court weeping, too. For one man, it was a victory over the worlds No. 1 tennis player that could resurrect a career he feared was over. For the other, it was a stunning loss that leaves him waiting four more years for a chance at an Olympic singles gold medal.Del Potro, the 2009 US Open champion stalked by injuries ever since, won 7-6 (4), 7-6 (2) in the first round Sunday at the Rio de Janeiro Games. After three left wrist surgeries that had him contemplating retirement, he is ranked just 145th.But when the big Argentine is healthy and smacking his signature forehand around the court, his play is worthy of the gold-medal match -- no matter that his backhand is still a work in progress.Amazing, amazing match for me, del Potro said. I didnt expect to beat Novak tonight, because I know my situation.These two faced off for bronze in London four years ago, with del Potro winning. But when he arrived at Wimbledon in June, he hadnt appeared at a major in 2? years.He would upset fourth-seeded Stan Wawrinka in the second round there, and even though a fatigued del Potro lost his next match, it was a hint that he might yet still have some greatness in him.Del Potro was just 20 when he rallied from a two-sets-to-one deficit to stun five-time defending champion Roger Federer in the US Open final. With the way his forehand rocked Federer that day, more Grand Slam titles seemed certain for the young Argentine.Then came a string of wrist injuries, first to the right, then the left -- which the righty needs for his backhand. He was still slicing often Sunday, but the two-handed shot is beginning to look more comfortable. And with the way he was booming his serves and forehand, del Potro put the pressure on Djokovic from the start.In the second-set tiebreaker, del Petro crushed two straight forehand winners on Djokovics serve to take a 3-0 lead. He made it 5-0 before Djokovic scored a point.Del Potro hit 41 winners Sunday, 29 on his forehand. It would be a forehand off the net cord, however, that clinched victory on his second match point.Djokovic, a 12-time major champion, had more unforced errors than winners: 32-26. The Serb, who will be 33 at the 2020 Olympics, called this one of the toughest losses in my life.Hes still alive in doubles, though, so a gold medal in Rio remains a possibility.At 2-2 in the first-set tiebreaker, del Potro won three straight points to take control. A big forehand that Djokovic couldnt get back gave him three set points, and he converted the second when Djokovics forehand sailed wide.In decisive moments, he just came up with some extraordinary tennis, Djokovic said of the player he described as a good friend of mine.Del Potros Sunday did not start off so auspiciously -- he was stuck in an elevator at the Olympic Village for 40 minutes before Argentine handball players freed him.Argentine player Federico Pizarro heard shouting coming from an elevator and opened the door to find del Potro, who had been trapped there during a power outage.Gonzalo Carou, another one of del Potros rescuers, said the team found the incident funny, but he said it could have been less amusing if del Potros preparations for his match had been disrupted.Its very difficult because del Potro has a very important match, Carou said.It was a hugely difficult match from both del Potros and Djokovics perspective -- each had the misfortune of drawing the other in the first round.It was a raucous atmosphere in the last match of the night on center court, where Argentine fans chanted for del Potro and Brazilians tried to drown out their rivals with cheers for Djokovic.Djokovic started the year with talk of a Grand Slam after he won the Australian Open and French Open. But he was upset in the third round at Wimbledon by 41st-ranked Sam Querrey. The 2008 Olympic bronze medalist seemed to bounce back by winning a hard-court tuneup in Toronto before coming to Rio de Janeiro.He told me really kind words at the end, del Potro said, and I appreciated that.

PHOENIX --The Diamondbacks have turned their current homestand into a study in the art of the walkoff.Three wins this week, three walkoffs.Three lost leads, three recoveries.The latest came Friday, when Brandon Drury scored on a two-out wild pitch after doubling with one out and taking third on a groundout. Drury broke for home when Blake Woods first pitch to Juan Segura was in the dirt.The play wasnt close, and the result wasnt new.Drury hit a walkout sacrifice fly in a 10-9 victory over Altanta on Wednesday, after the Braves tied the game with a four-run rally in the ninth inning.Paul Goldschmidt hit a walkout homer in the ninth inning for a 9-8 victory Monday, the first game of the seven-game homestand, after Freddie Freeman tied the game with a homer in the top of the inning.Cincinnati will attempt to break the trend in the second game of a three-game series Saturday evening, when right-hander Anthony DeSclafani opposes Zack Godley at Chase Field.Any time you pick our teammates up and help the team win games, thats a really good feeling all the way around, Drury said. You have to keep battling and pick your teammates up. Thats what the name of the game is, and were going to keep on do that. I do feel like things are keep turning and we are going to play really good baseball.Arizona has won eight of 13 and 12 of 19 after falling 22 games below .500 the first week of August.Arizona welcomed the return of center fielder A.J. Pollock on Friday. Pollock, an All-Star in 2015, had been on the disabled list after re-fracturing his right elbow in an exhibition game three days before the start of the regular season. He was activated Friday and went 0-for-5, although his slow grounder to second base in the 10th inning drove in Phil Gosselin to tie the game at 3, forcing another inning.Itss like opening day for me, Pollock said.dddddddddddd You have to get all of the first stuff out of the way. It was good to be out there.Pollock received nice ovations each time he batted, and he made a stretching catch to take extra-bases away from Cincinnati second baseman Brandon Phillips on a long fly to right-center field for the second out of the fourth inning.I felt good out there, Pollock said. Physically, it is not an issue any more. It is good to be out there with the team, and to get this win is huge.Cincinnati got another strong outing Friday from left-hander Brandon Finnegan, who struck out a career high 12 in six innings. He struck out the side in the first and fifth innings, and he gave up only three hits. Finnegan struck out eight and gave up one hit in seven scoreless innings in his previous start against the Dodgers.Everything was working for me and I was hitting spots, Finnegan said. It was a good night.Arizona kept Cincinnatis hottest bat, Joey Votto, at arms length in the first game of the series. Votto was 1-for-3 with a single and three walks (two intentional). Arizona intentionally walked him with runners on first and third and two outs in the ninth inning to bring up Adam Duvall with the game tied at 2. Duvall flew out to deep center.Votto was walked with a runner on second base and two outs in the 11th to get to the pitchers spot in the order, and the Reds were unable to capitalize that time either.Votto hit .413 in July and is hitting .418 with 22 RBI in August. He is attempting to become the first major leaguer since 2010 to hit .400 in consecutive months since Josh Hamilton hit .454 in June and .418 in July for Texas in 2010.
