Sampras predicts Federer will break Slam record

Take it from no less an authority than Pete Sampras: Roger Federer is more dominant than he was and will break his record of 14 Grand Slam titles. Still, Sampras isn't prepared to cede his place in history just yet.

Asked how Sampras in his prime would fare against Federer, the 36-year-old American said it wasn't a fair comparison. "For me, in my prime, I felt unbeatable," Sampras said Friday. "In Roger's days, he's unbeatable. It's really hard to put one guy over the other. Having said that, I think Roger is dominating the game much more than I ever did. I think he's going to go on and past 14 and win 16, 17, 18 majors."

Federer has won 12 Grand Slams titles, two short of Sampras' mark. "I think he's going to break all records," Sampras said. The two tennis greats arrived in the Chinese gambling enclave of Macau for the last of their three-match Asian exhibition series. Sampras, who retired in 2002 after winning the U.S. Open, lost the first two matches in straight sets.
