The American had never beaten Federer in five previous meetings, but he completely outplayed the Swiss and won in just over an hour.

He won the opening three games and had a break point for 4-0 as he dominated the first set, before breaking at the start of the second.

A Federer comeback seemed certain but there was nothing there, and although he saved two match points at 5-1 down he could not deny Fish an incredible win.

"I have a great record against him and I have always controlled matches against him," said Federer.

"Today was different, a tough result. He came up playing very, very well.

"He took everything on the rise and hit winners. I just couldn't get to his second serve and that was the disappointing part of today."

Federer revealed last week that he was diagnosed with mononucleosis (glandular fever) at the start of the year but claimed to be getting back to full fitness in Indian Wells.

In the first semi, Nadal could not match last year's final win over Djokovic.

The Spaniard took a 6-2 head-to-head record into the match and grabbed an early break, but Djokovic levelled at 2-2 and broke again for 5-3 with a net cord, serving out the set with an ace.

Nadal was struggling on serve and he lost the last four games as Djokovic dominated.
