MACAU: Former world number one Pete Sampras beat long-time rival Andre Agassi at an exhibition match in Macau Sunday, the first time that the retired American champions have faced off in seven years. Sampras, 38, lost the first set 3-6 but rallied to take the second 6-3 and then finished off the 39-year-old Agassi in 10-8 tie-breaker at The Venetian hotel in the southern Chinese gambling enclave. The pair, who played against each other 34 times in their professional careers, last met at the 2002 US Open. Sampras won the match to grab a record 14 Grand Slam titles -- later surpassed by Swiss Roger Federer.
