O. J. Mayo, American basketball player

Ovinton J'Anthony Mayo (born November 5, 1987) is an American professional basketball player for UNICS of the VTB United League. He played a single season of college basketball for the USC Trojans while earning first-team All-Pac-10 honors. However, he was retroactively declared ineligible when it was discovered that he had received improper benefits in violation of NCAA rules before he even played a game, and the Trojans vacated all of their 21 wins from the 2007-08 season.

Mayo entered the 2008 NBA draft and was selected by the Minnesota Timberwolves with the third overall pick. He was later traded to the Memphis Grizzlies, with whom he played four seasons. Mayo signed with the Dallas Mavericks in 2012, and then with the Milwaukee Bucks in 2013. In July 2016, Mayo was banned from the NBA for violating the league's anti-drug program. After a two-year hiatus, he resumed his career with Atléticos de San Germán of the Baloncesto Superior Nacional (BSN) in Puerto Rico.
