The 24th seed won 7-5 3-6 7-6 (10-8) 6-4 to reach the last four, thrilling his large contingent of supporters in New York.
He goes on to face top seed Rafael Nadal, who earlier beat Russian teenager Andrey Rublev.

Top seed Nadal is now also guaranteed to keep hold of the number one ranking ahead of Federer.
