His best result at Wimbledon was reaching the semifinals in 2008, beating No. 3 Novak Djokovic en route. He often lost in the first or second rounds in other years, although he made the quarterfinals in 2001, losing in four sets to eventual champion Goran Ivanišević. Safin dismissed his performance in the 2001 tournament as a result of luck. Safin disliked playing on grass. Safin has said: "It's difficult to serve. It's difficult to play-off the baseline because a lot of bad bounces." With Safin's semifinal performance at Wimbledon in 2008, he became the fourth of five active players at the time to reach the semifinals in all four Grand Slams, joining Roger Federer, David Nalbandian, and Novak Djokovic. Other active players have since then joined the list.
