"I felt so fresh," he said. "I didn't feel nervous really at all, apart from at the beginning of the match."
He won with plenty of flair and a succession of spectacular shots. A lunging backhand pass in the corner had fans on their feet. And he erased a break point with an acrobatic leaping overhead, followed by an improbable reflex volley winner after Federer fired at him from point-blank range.
Murray fell behind 15-40 serving in the opening game but rallied to hold, and from 2-all he took charge, winning every game until 5-0 in the second set.
Federer struggled to hold but had many chances to break, including in the third game of the second set. He held six break points but Murray erased them all and won the game on the 20th point on an errant Federer backhand, one of many.
Federer, taxed by his 19-17 third-set semifinal win Friday, couldn't summon a comeback. Murray hurried to the finish line, winning the final set in 33 minutes.
He reached match point with an ace, then hit another at 131 mph to seal the win. He briefly sank toward the turf, then rose to share a warm embrace with a smiling Federer.
"I was very happy for him," Federer said. "It's a long time coming for him, and he did great."
Murray climbed into the player box to share hugs with friends and family. He then leaped back onto the court, and when he threw a final knockout punch, the crowd roared one more time.
