Andy Murray claimed his biggest scalp in almost four years as he shocked Alexander Zverev in New York.
In his second competitive match of 2020, the Scot beat the world No 7 in three sets 6-3, 3-6, 7-5 in the second round of the Western and Southern Open, a warm-up event for next week’s US Open.
Murray is ranked 134 as his plots his way back to the top level after years of hip problems.
Monday’s match with Zverev was just his second against a top-10 opponent since the 2017 French Open — the tournament where he suffered the hip injury which led to two operations and threatened to end his career.
But, against the 23-year-old German, Murray showed he is fit and can still beat the best as he saw off his highest-ranked opponent since his victory over Novak Djokovic in the final of the ATP World Tour Finals in 2016.
Murray broke Zverev in the fourth game of the first set and went on to take it in 49 minutes.
Zverev rallied in the second set and, after squandering earlier chances, eventually broke Murray and then served out to take the match to a decider.
Zverev’s second serve is his Achilles heel and he fell apart completely at the end of the final set.
He hit three double faults when serving for the match at 5-4 and then another two as Murray broke again to seal a terrific victory.
British No 1 Jo Konta thrashed Belgian Kirsten Flipkens 6-2, 6-0 to set-up a last-16 match against Vera Zvonareva.
