Oscar De La Hoya vs. Julio César Chávez II, billed as Ultimate Revenge, was a professional boxing match contested on September 18, 1998 for the WBC welterweight championship.

[4] De La Hoya would defeat Whitaker to capture the title and then go on to successfully defend it three times before a rematch with Chavez was announced in April 1998.

The bout was contingent on both De La Hoya and Chavez winning their tune–up fights against Patrick Charpentier and Ken Sigurani respectively, which both men did, officially putting their rematch on.

The fight's eighth and final round was action-packed, as both fighters traded shots and threw a combined 173 punches with De La Hoya landing 45 to Chavez's 38.

However, as in the first fight, Chavez took a brutal beating and was forced to quit on his stool due to all the damage he had received through the entire contest.
