Federer Finally Loses a Grand Slam Match in Which He Led Two Sets to None

Roger Federer hasn't been winning Grand Slam tournaments lately, but one way he appeared to be unassailable was when he won the first two sets (in a 3-out-of-5 format) in one of the Slam events (Wimbledon and the Australian, French, and U.S. Opens). Before today, in fact, he was 178-0 when ahead two sets to none in a Grand Slam event. That streak is now over, as Federer lost at Wimbledon to Jo-Wilfried Tsonga, 3-6, 6-7 (3), 6-4, 6-4, 6-4.
