Alexander Zverev's quest for a first grasscourt title took an unexpected turn at the Halle Open on Friday when the German second seed was forced to sprint from court to vomit mid-match before rallying to defeat Italy's Flavio Cobolli 6-4 7-6(8).

Daniil Medvedev continued his impressive record against Alexander Zverev on Saturday to deny the German on home grass and reach the Halle final. The third seed prevailed 7-6 (7-3), 6-7 (1-7), 6-4 over the second seed in the semi-final of the Wimbledon warm-up in the west of Germany.

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