“Absolutely relentless.” Those were the words commentator John McEnroe used to describe Rafael Nadal today. Nadal defeated Roger Federer 7-5, 7-6 (3), 5-7, 6-1 in the final of the French Open this afternoon to win his sixth title in Paris, equaling Bjorn Borg’s all-time record. The 25-year-old Spaniard improved to 45-1 at Roland Garros, while winning his 10th Grand Slam championship. Nadal won four successive French titles from 2005-2008 and a fifth in 2010. Nadal’s only loss in Paris came in 2009 in the fourth round at the hands of Robin Soderling. The win guarantees Nadal holding onto the No. 1 spot in the ATP Rankings on Monday. Had Federer won, No. 2-ranked Novak Djokovic would have climbed to the top of the rankings. Djokovic had his 43-match winning streak snapped by No. 3-ranked Federer on Friday in the semifinals. Nadal was almost bounced from the tournament in the first round, when he had to rally to defeat American John Isner. “A big personal satisfaction, especially when you started [the tournament] without playing your best,” Nadal said. “Finally, I was able to play my best when I needed my best. [The French Open] always is the tournament where I feel that I have more chances to win. This is my biggest chance of the year [to win a Grand Slam]. I know if I win this tournament, my season is fantastic. I then can play with more confidence and less pressure.” Federer started fast, breaking Nadal in the second game, and raced to a 5-2 lead in the opening set before the wheels started to come off for the Swiss star. Rafa faced a break point in the next game, but saved it when Federer’s backhand drop shot was ruled just wide. A forehand return into the net and a Nadal backhand winner gave the Spaniard the game. Rafa broke Federer’s serve three straight times to take the first set and a 2-0 lead in the second. Federer got the break back in the eighth game to even things up at 4-4, but gave it right back. With Nadal serving at 5-4 and 40-40, play was suspended by rain. Upon resumption, the Spaniard proceeded to drop serve. Two holds forced a tiebreaker, which Nadal won handily. Federer served out the third set after getting a key break in the 11th game. The cruncher for Federer came in the fourth game of the fourth set, when Nadal broke at love. Another break and the match was history. Despite the loss, Federer battled valiantly. “As it often happens, he’s the best on clay,” Federer said. “He proved it once again.” Nadal improved to 17-8 against the former world No. 1, including 6-2 in major finals.
