After beating rival Pete Sampras, 29, to win the Mercedes-Benz Cup on Sunday, Andre Agassi joked that the baby that he and Steffi Graf are expecting would beat any future baby from Sampras and his wife of less than a year, actress Bridgette Wilson, 27. “I’ve got a hundred bucks that says my baby beats Pete’s baby,” Agassi, 31, told the crowd at the Los Angeles Tennis Center, as quoted by the Associated Press. Agassi and Graf, 32, are expecting a baby boy in December. The Samprases have yet to start a family. Agassi did go on to boast, “I’ve got genetics on my side,” though Sampras believes his 6-foot-1 height combined with Wilson’s 5-9 stature would be an advantage over the 5-11 Agassi and 5-9 Graf. “The only thing is, if I have a little girl, I could be in trouble,” Sampras admitted.
