Jimmy Connors and Wimbledon and the U.S. Open
Everyone knows that Federer passed Jimmy Connors for most Grand Slam semifinals at this year's Wimbledon with 32 Grand Slam semifinals. However, 9of Federer's semifinals are at the Australian Open, which Connors only played twice and 7 are the French Open, which Connors often skipped.
Federer has been 16 U.S. Open and Wimbledon semifinals, this is tied for third most all time. Sampras has 17. Amazingly, Connors was in 25 U.S. Open and Wimbledon semifinals. Even as a Federer worshiper, I can not imagine Federer exceeding this achievement. Quite awesome from Jimbo.
