An earthquake failed to stop Alexander Zverev from beating fellow German Dominik Koepfer to reach the Mexican Open final in Acapulco.
Koepfer was serving in the second set when the 5.7-magnitude quake struck.
“The lights started shaking and the crowd felt it more than we did,” said world number seven Zverev, who faces Stefanos Tsitsipas in the final.
The tremors hit shortly after British duo Ken and Neal Skupski had beaten compatriot Joe Salisbury and his partner Rajeev Ram to reach the doubles final.
Ken Skupski said the tremor “lasted maybe five seconds” but was “enough to freak you out”.
“I’ve never experienced one,” he said. “I’m hoping that this is the only one that they’re going to have here because obviously there’s a fear of bigger and stronger ones in the coming hours or days.”
