Alexander Zverev recovered from feeling unwell in the first set to defeat Flavio Cobolli 6-4, 7-6 in the Halle Open tennis quarterfinals.

Alexander Zverev threw up in the middle of his Halle Open quarterfinal match with Italy's Flavio Cobolli before rallying to advance to the semifinal.

After a warm-up and claiming a break in the very first game of the match, the German tennis star rushed off the court in the middle of the second game. While some found it bizarre and funny, some instantly pointed out that the top seed probably wasn't feeling his best.
