After prematurely being awarded his 11th world title earlier in the week by the Association of Surfing Professionals, Kelly Slater made it official on Sunday.

Slater outlasted Gabriel Median and Miguel Pupo with a score of 17.17 in his heat at the Rip Curl Pro Search San Francisco at Ocean Beach, securing the title which he thought he had already wrapped up on Wednesday.

After crowning Slater as champion, the ASP Tour acknowledged a miscalculation in its tiebreakers on Friday and said Slater needed one more heat win to official eliminate Owen Wright from contention.

Slater is the oldest season champion in ASP history. He was the youngest champion in 1992 when he won at 20.
