MACAO, Nov. 24 (Xinhua) -- The retired U.S. tennis legend Pete Sampras shocked the present World No. 1 Roger Federer Saturday by 7-6, 6-4 in the Venetian Macao Tennis Showdown, the last stop of their Asian exhibition match tour.

"I guess it's one for the old guys," Sampras joked at the award ceremony. He said at the press conference later on, "I made it competitive and I am serving very well."

"Pistol Pete" displays his trademark serves and volleys Saturday. The former world top player won the first set on a tie-break by 10-8 when neither player could reach a break of serve.

Sampras got the first but vital break of the match at 4-4 in the second set and went straight for the victory by 6-4.

"It's been tough beating my childhood hero, but I am happy he got me at least once, " said Federer. The first two matches in the series of three were won by Federer 6-4, 6-3 in Seoul and 7-6, 7-6in Kuala Lumpur earlier this week.

"Sorry to disappoint you, but I am not coming back, " Sampras said when asked about whether he would return from retirement.

36-year-old Sampras, who retired from professional tennis five years ago, had won a record 14 Grand Slams. 26-year-old Federer, who owns 12 titles, is expected to break the mark in 2008.

The two met only once before on the ATP tour, in the fourth round of Wimbledon in 2001 when Federer defeated Sampras in five sets.

The Asian tour gained worldwide attention and 12,000 seats for the Venetian Macao Tennis exhibition match were sold out in a few days.
