Andy Murray produced a brilliant performance to beat world No 7 Alexander Zverev in three sets in the second round of the Western & Southern Open in New York.
Playing in only his second ATP Tour match of the year, Murray came through 6-3 3-6 7-5 to secure his first win over a top-eight player since the ATP Finals in 2016.
Zverev served for the match at 5-4 in the final set but tossed in three double faults - taking his total in the contest to nine - in the face of some aggressive return positioning from Murray.
Murray will next face Milos Raonic, who beat Dan Evans in straight sets.
"It was a big one to get through," said Murray.
"I'm satisfied to get through it against a top player having not played for such a long time and I get another opportunity to compete again tomorrow. This will give me an idea of where my body is at."
Murray looked bright in the early stages and broke to move 3-1 ahead as he regularly stepped up into court to attack the German’s second serves.
Zverev threatened to break back but Murray recovered from 15-40 down to move 5-2 ahead, winning the game with a brilliant forehand winner on the run.
