Input: Question: Who won the 1989 Royal Rumble? Passage:At the 1988 King of the Ring tournament, Bass qualified for the final after beating a young Shawn Michaels but was paid by Ted DiBiase to fake an injury. Bass began a feud with Beefcake in August 1988, gouging Beefcake's head open with his spurs ("Bret" and "Bart") on an episode of Superstars of Wrestling; the attack caused Beefcake to miss his scheduled Intercontinental championship match against the Honky Tonk Man at the first SummerSlam event on August 29. Bass and Honky co-captained a five-man contingent against a team captained by Beefcake and the Ultimate Warrior at the second Survivor Series in November. Bass and teammate Greg Valentine were eliminated by Warrior in succession in the final minute of the match. On the January 7, 1989 Saturday Night's Main Event XIX, Bass lost to Beefcake via sleeperhold in a hair vs. hair match. He competed in the 1989 Royal Rumble (sans hair), Bass' feud with Beefcake was scrapped, and he was used mainly as a preliminary wrestler and left the WWF shortly thereafter.
