German veteran Philipp Kohlschreiber produced one of the shocks of this year’s US Open men’s competition with a 6-7 (1-7) 6-4 6-1 6-3 win over fourth seed Alexander Zverev in the third round.
Zverev, 21, made 52 unforced errors against his compatriot and converted only three of 13 break-point chances.
He capitulated in the third set and failed to hold a break in the fourth.
Kohlschreiber, 34, will now play Diego Schwartzman or Kei Nishikori.
The German world number 33, who beat a top-five player in a major for only the second time, said: “It’s an awesome feeling, the crowd was amazing.
“I think it was a really entertaining match. I’m very pleased with my performance.
“I returned very well. The short slice worked – he wasn’t moving too well to the net. Lucky me today.”
Elsewhere, Australian John Millman, 29, will play five-time Roger Federer after reaching a Grand Slam fourth round for the first time with a 6-4 4-6 6-1 6-3 win over Mikhail Kukushkin of Kazakhstan.
Millman, who has trained with Federer in Switzerland, said: “I’ve got a lot of respect for Roger. I’ve got a lot of respect for his team.
“He’s got an aura about him. Definitely a player I’ve looked up to throughout my career.”
Portugal’s Joao Sousa surprised Lucas Pouille, the French 17th seed, with a 7-6 (7-5) 4-6 7-6 (7-4) 7-6 (7-5) win. The world number 68 will face either Wimbledon champion Novak Djokovic or French 26th seed Richard Gasquet in round four.
