Even though the stakes may not be as high as in their epic clashes of the past, Andre Agassi and Pete Sampras' match this Sunday will be anything but a friendly exhibition. The two American greats, who had one of tennis' great rivalries, will play each other in the southern Chinese gambling enclave Macau. “It's going to be competitive tennis – obviously not quite as cutthroat as it once was - but I still feel we can both play quite well,” Sampras said Thursday. “As much as its an exhibition, there's still a lot of pride. Our egos are pretty big. Once the first point starts, I'm going to want to beat him. Whenever I stepped out against Andre when we were playing, it was like a heavyweight fight. That's one thing I miss.” Both have been brushing up on their game in recent months, ensuring their will not be too much rust for Sunday's showdown. Sampras, 38, played on the ATP seniors tour last year and Agassi made a one-time appearance at a seniors event in Arizona earlier this month, where he won two matches before losing to fellow American Todd Martin in straight sets in the final. Agassi, 39, has been playing consistently in recent months and Sampras said he's been practicing against juniors in Los Angeles. The former world No. 1s have 22 Grand Slam titles between them – eight for Agassi and 14 for Sampras. Agassi is one of six men in history to win all four majors and won Olympic gold in Atlanta in 1996.
