Nadal Upset by Czech Rosol at Wimbledon Chasing a drop shot in the second set, Rafael Nadal stumbled and tumbled into the net as his racket went flying to the sideline. It just wasn't his day. Nadal rose slowly to cheers from the Wimbledon crowd but found himself off balance the rest of the way and made his earliest Grand Slam exit since 2005. Nadal was overpowered in the second round Thursday by Lukas Rosol, a Czech ranked No. The 26-year-old Rosol earned the biggest win of his career playing in Wimbledon's main draw for the first time. He lost each of the past five years in the first round of qualifying. As the match stretched beyond dusk, the conclusion came with the retractable roof closed for the final set on Centre Court. The upset on tennis' biggest stage was no fluke: Rosol served brilliantly and repeatedly stepped instead the baseline to hit aggressive groundstrokes, while Nadal found himself pinned deep and on the defensive. Among those shocked by the result was Rosol. "I'm not just surprised; it's like a miracle for me," he said. I never expected something like this. Nadal saved three set points to win the opening set, but his demeanor grew glum as Rosol overtook him. After falling behind in the third set, Nadal grumbled to the chair umpire during a changeover, apparently irritated by Rosol's movements as he awaited serves.

"I was concentrating on myself," Rosol said. I don't know what he was complaining about. Two games later, Nadal bumped into Rosol - and didn't acknowledge the contact - as they walked to their chairs for a break. Rosol exhaled before hitting his final shot, which was his 22nd ace. He fell to his knees, arms up, then collapsed face down on the famous grass. He then rose and shook hands at the net with a frowning Nadal. "I think I was better today a little bit," Rosol said. Rosol became the lowest-ranked player to defeat Nadal in a major tournament. The 6-foot-5, 178-pound Czech lost only 16 points on his first serve, cracked his returns into the corners and won 22 of 28 points at the net. In short, it was a complete performance that had spectators wondering why they'd never heard of him before. Nadal lost despite committing only 16 unforced errors in 276 points. The Spaniard had reached the final in the past five Grand Slam tournaments, and had played in the final of his past five Wimbledons. It was a good day for Americans - Serena Williams, Andy Roddick, Mardy Fish and No. 126-ranked Brian Baker advanced, as did No. 28-seeded Christina McHale and Varvara Lepchenko. Maria Sharapova's old serving problems resurfaced, costing her the second set before she recovered to beat dangerous Tsvetana Pironkova, 7-6 (3), 6-7 (3), 6-0. The Court 1 match took two days and ended three minutes after Williams concluded her victory on Centre Court, beating qualifier Melinda Czink 6-1, 6-4. Defending champion Petra Kvitova, seeded fourth, advanced by beating Elena Baltacha of Britain 6-0, 6-4. Roddick advanced to the third round at a Grand Slam tournament for the first time in 2012 when he beat Bjorn Phau 6-3, 7-6 (1), 6-3. Roddick is seeded only 30th and fended off questions in recent months about retirement before he won his fifth grass-court title last week as a wild card at Eastbourne.
