Andy Roddick advanced to the final of the Legg Mason Tennis Classic at Washington, D.C., for the fourth time, beating John Isner 6-7 (3), 6-2, 7-5 Saturday. The top-seeded Roddick is a three-time winner of the event. He will face last year's champion, No. 2 seed Juan Martin del Potro, who defeated Fernando Gonzalez 7-6 (2), 6-3. Roddick and Isner were even through most of the third set until Roddick broke Isner to go up 6-5. "I was getting break points, I wasn't converting," Roddick said in a television interview immediately after the match. "But it wasn't because I wasn't putting returns on the court or putting pressure on him, he was coming up with the goods." Isner had skirted trouble earlier in the set. He faced break point at 4-all before he fought back and closed out the game with his 19th ace. He was not as lucky his next service game, hitting an attempted crosscourt forehand into the net on the second break point. Roddick then closed out the match, finishing with a backhand winner down the line. Del Potro picked up his first career win against Gonzalez in four attempts. The two last met in the 2007 Australian Open. "It was very tough for both of us," del Potro said. "The court was so hot, and after the first set Fernando was so tired. I feel tired, too, but with my serve I had short points." Temperatures in the Washington area were in the mid-80s with moderate humidity for the afternoon match.

Samantha Stosur routed Sorana Cirstea of Romania 6-3, 6-2 and advanced to the final of the LA Women's Tennis Championships in pursuit of her first career singles title. The 25-year-old Australian is known as a doubles specialist, having won 22 career titles, achieved the No. 1 ranking and earned two Grand Slam mixed titles. She's enjoying a strong start to the summer hardcourt season, having reached the semifinals last week at Stanford with a three-set win over Serena Williams. Stosur will seek to end her status as perennial runner-up in today's final, where she will play either Maria Sharapova or 10th-seeded Flavia Pennetta of Italy, who met in a night semifinal. Stosur has lost in four career singles finals, including one last year in Seoul. A victory Sunday could boost the Aussie into the top 15 for the first time from her current ranking of 19th. Stosur lost just four points on her serve in the first set, dominating with three love games. She earned the only break in the second game, also the only one that went to deuce. She won 81 percent of her total service points in the 62-minute match. Stosur served three of her seven aces in the second game of the second set. She then led 2-1 after breaking Cirstea, who committed 25 unforced errors in the match. She went up 4-1 with another service break and closed out the match when Cirstea pulled a backhand service return wide. Cirstea, a 19-year-old Romanian, was bothered by pain from plantar fasciitis in her right foot, the same problem she had in Friday's three-set win over Agnieszka Radwanska of Poland.

Golf

John Rollins doubled his lead in the Legends Reno-Tahoe Open, shooting a 5-under 67 to move four strokes ahead of Ryan Palmer. Rollins, who tied the course record with a 62 on Friday, had three birdies and three bogeys on the front nine, then rolled in a 30-foot eagle putt on the par-5 11th and added two birdies to finish at 16-under 199 at Montreux Golf & Country Club. Palmer started the day five strokes off the lead, but birdied three of the first four holes and shot a 66 to reach 13 under. Joe Ogilvie was another stroke back after a bogey-free 66 that included an eagle and four birdies. Martin Laird (66) was 11 under. He finished birdie-birdie-birdie-eagle, holing a 77-yard approach to the par-4 18th that spun back 20 feet into the cup.

Jennifer Song moved within a victory of becoming the second woman to win two U.S. Golf Association championships in the same year, beating Tiffany Lua 3 and 2 in the U.S. Women's Amateur semifinals at St. Louis. The 19-year-old Song, the U.S. Women's Amateur Public Links winner in June and low amateur last month in the U.S. Women's Open, will face Jennifer Johnson today in the 36-hole final at Old Warson. Johnson beat 14-year-old Alexis Thompson 1-up. Pearl Sinn is the only woman to win two USGA titles in a year, taking the 1988 Women's Amateur and Women's Amateur Public Links. Five men have accomplished the feat. "I am so excited," said Song, coming off her freshman year at Southern California. "Being given this chance to play in the finals is just a great honor for me." Song, from Ann Arbor, Mich., never trailed against the 18-year-old Lua, an incoming UCLA freshman from Rowland Heights, Calif., in hot and breezy conditions on the 6,468-yard, par-71 layout. The 17-year-old Johnson, an incoming freshman at Arizona State, hasn't trailed through five matches and 76 holes.

Soccer

Landon Donovan scored, then jumped into David Beckham's arms, and the Los Angeles Galaxy celebrated their fifth win in six games with a 2-1 victory over the New England Revolution at Foxborough. The display of togetherness came barely two months after Donovan criticized Beckham's leadership and commitment in a book about Beckham's stint with the Galaxy. Donovan scored in the 21st minute, when Alan Gordon's shot ricocheted off Revolution defender Darius Barnes. Donovan volleyed a shot from about 20 yards on the right that curled just inside the far post and past goalkeeper Matt Reis. Jovan Kirovski's goal made it 2-0 in the 52nd minute, and Steve Ralston scored for the Revolution on a penalty kick in the 83rd. The Galaxy improved to 5-0-1 in their last six games, while the Revolution lost for the first time in five games, going 2-1-2.
