Pete Sampras rolled back the years with a fine 7-6 (8-6) 6-4 win against Roger Federer in the third and final match of their Asian exhibition series.
Sampras ran Federer close in match two before winning in Macau
Sampras, who retired in 2002, won both his break points against the world number one to seal victory in Macau.
"It's one for the old guy," said the 36-year old American afterwards.
Swiss star Federer, 26, had won the previous two matches earlier this week, beating Sampras 6-4 6-3 in Seoul and 7-6 (8-6) 7-6 (7-5) in Kuala Lumpur.
He was quick to praise Sampras, saying: "We delivered a great level of play. The surface was really quick and Pete was playing really well and hardly making any mistakes."
Sampras added: "The quick conditions helped my service games. I got going a little bit today, but it could have gone either way in the first set."
Federer won his 12th Grand Slam title at the US Open in September and is closing in on Sampras's record of 14.
The two met only once on the ATP Tour, in the fourth round of Wimbledon in 2001, when Federer beat Sampras in five sets.
