James Blake shocked top seed Lleyton Hewitt to win the Tennis Channel Open in Las Vegas on Sunday.
Blake beat Hewitt for the first time in seven attempts
Blake, seeded fifth, won 7-5 2-6 6-3 to claim his first win against Hewitt in seven attempts.
"I'm happy to finally get a win against one of the best players of all time," said Blake after securing his fifth career title.
Blake is now expected to rise to a career-high 14th in the world when the rankings are released on Monday.
Blake, the fifth seed, had only dropped serve once in 36 games going into the final but was broken four times by Hewitt, including three times in a row to close the second set.
Blake responded by hitting 20 winners in the third set and paid tribute to Hewitt after the match.
"He made me earn it today," said Blake. "He's gotten me in so many close matches and beaten me up so many times."
Hewitt has not won a title for more than a year but was full of praise for Blake.
"He's on a great run," said Hewitt. "Blake has come back as one of the best players out there.
"There are a lot of positives that came out of the last two weeks."
