Tennis: "I didn't know what happened" - Zverev on playing through earthquake

Alexander Zverev said he and his opponent Dominik Koepfer had no idea an earthquake struck in the middle of their Mexican Open semifinal match in Acapulco on Friday. With Koepfer serving in the second set of Zverev's 6-4 7-6 (5) win, the stadium started rattling causing television cameras to shake, but the two continued to play on. Zverev said he only realised an earthquake happened by the reaction of the crowd. Mexico's National Seismological Institute said the quake had a magnitude of 5.7 and the epicentre was 60 kilometres southeast of the city of San Marcos, located inland from Acapulco near the Pacific coast.
