Argentine Juan Martin del Potro finally got off the schneid against No. 1-ranked Roger Federer this afternoon, defeating the hometown favorite 6-4, 6-7 (5), 7-6 (3) in the finals of the Swiss Indoors Basel. Del Potro had lost seven straight matches to Federer, including six this year. The big Argentine improved to 3-13 lifetime against the top-seeded Swiss, while winning his second consecutive title and fourth of the year. Del Potro, No. 8 in the world, won last week in Vienna, and at Estoril and Marseille earlier this season. Federer, appearing in his ninth Basel final, has won the tournament five times. “It was an unbelievable final, the match was really close,” Del Potro said. “After six losses, it was a big win for me. I was fighting all the time. I got lucky in the end, but I felt that I played a really good match.” The second-seeded Del Potro played rock solid in the opening set, winning 20 of his 25 service points and not facing a break point. He broke Federer in the fifth game, when the Swiss netted a routine backhand, and maintained his advantage to win the set in just 35 minutes. Federer tightened up his game in the second set, as both players held serve with relative ease — each facing but one break point — to force a tiebreaker. The Swiss Maestro got the only mini-break in the tiebreaker at 1-1 and finished out the set on serve to even things up at a set apiece. Del Potro saved three break points in the third game of the final set, before clinching the game with an ace. He saved another break point in the seventh game, closing it out again with an ace. Down 5-6 and 15-30, Federer served three straight aces to force another tiebreaker. Del Potro got his second mini-break of the decider to seal his 13th career title in two hours and 44 minutes. “Overall, I played pretty well,” Federer said. “He got off to a better start and made the best of it. He was better than me in the first set. It was close in the second and he didn’t play a very good tiebreak. I had my chances in the third and couldn’t take them. I tried to take it to him but it wasn’t enough today.” Federer served 18 aces to 10 for Del Potro. The Argentine was 1-2 on break points, though, while Federer was 0-5.
