The Rock was then entered into the "Deadly Game" tournament for the vacant WWF Championship. The finals occurred at Survivor Series, where the Rock defeated Vince McMahon's associate, Mankind, to win his first WWF Championship. A "double turn" then occurred as the Rock turned heel again after allying with Vince and Shane McMahon as the crown jewel of their stable, The Corporation, after the McMahons betrayed Mankind. On December 13, 1998, at the pay-per-view named after him, , the Rock had a rematch with Mankind for the WWF Championship. Mankind appeared to win the match when the Rock passed out to the Mandible Claw submission move, but Vince McMahon ruled that since the Rock did not tap out, he retained his title.
