In the following weeks, the Rock continued his feud with Triple H and eventually won his fourth WWF Championship, which he won on April 30, at Backlash, after Stone Cold Steve Austin intervened on his behalf. The following night on "Raw", he successfully defended his title against Shane McMahon in a Steel Cage match. On May 21, at Judgment Day, the Rock faced Triple H in an Iron Man match with Shawn Michaels as the special guest referee. With the score tied at five falls each, and with seconds left on the time limit, the Rock was disqualified when The Undertaker attacked Triple H, thus giving Triple H the 6–5 win and the title. The Rock won the WWF Championship for a fifth time at King of the Ring on June 25 by scoring the winning pin in a six-man tag team match, teaming with Kane and The Undertaker against Shane McMahon, Triple H and Vince McMahon, whom he pinned. The Rock successfully defended the championship against Chris Benoit, on July 23, at Fully Loaded. The next month, he successfully defended his title against Kurt Angle and Triple H at SummerSlam. The Rock had another successful title defense against Benoit, Kane and The Undertaker, on September 24, at Unforgiven.
