Washington:Andy Roddick has advanced to the final of the Legg Mason Tennis Classic for the fourth time, setting up a meeting with Juan Martin del Potro.
Roddick beat American compatriot John Isner 6-7 (3), 6-2, 7-5 on Saturday and Argentina's del Potro downed Chilean Fernando Gonzalez 7-6 (2), 6-3, setting up a clash of the two top seeds in the final.
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 4-4 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.
"Every service game I held was just a battle," Isner said. "Eventually he kind of broke me down, got me at 5-5, and that was it."
Roddick only faced two break points in the match, saving both in the third game of the first set.
Both players relied on big serves. Isner had 20 aces and did not double fault, while Roddick had nine aces against one double fault.
Roddick, who entered with a 29-6 record in tiebreakers this year, had a rare tiebreaker loss in the first set. He wasted no time reasserting himself, getting the first service break of the match in the second set's opening game. He broke Isner a second time for a 5-2 lead, and served out the set.
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 around 30 C (mid-80s F) with moderate humidity for the afternoon match.
Serving down 5-6 in the first set, del Potro faced three break points in a game that went to deuce six times. He forced the tiebreaker when Gonzalez's shot landed just beyond the baseline during a lengthy rally, and quickly jumped ahead to take the first set.
The Argentine then broke the fourth-seeded Gonzalez twice to go up 5-0 in the second set.
"It was tough, physically and mentally, after that first set," Gonzalez said. "If you win the set and you're tired, you're still high. ... When you lose that kind of set, the beginning of the next set is really important and he took the big advantage."
Gonzalez's fatigue showed early in the second set when he fell to the court during a point. Gonzalez stayed there for a moment, and when del Potro walked toward the net, Gonzalez smiled and reached out a hand. Del Potro stepped over the net and helped Gonzalez up to the cheers of the crowd.
"I was thinking, 'Lay down with him,'" del Potro said. "But if I do that, we'd never stand up."
Gonzalez had 34 unforced errors, and del Potro had 29 as both players struggled at times in the conditions.
"We didn't play good tennis," Gonzalez said. "We were really tired and we were missing many balls."
