Tsitsipas’s shoe issues

The Tsitsipas victory was marked by his third straight game with a delay to change left shoes, having said he damages the laces when he slides incorrectly. “There’s nothing I can do about it,” he said. “The only thing is probably change my footwork, stop doing that.” Russian third seed Daniil Medvedev advanced to the semi-finals by defeating Croatian sixth seed and 2014 US Open champion Marin Cilic 6-4, 7-6 (9/7).

Medvedev, chasing his fifth career ATP title, took the only break at the start and never faced a break point. “I managed to do what I had to do, hold my serve and win the tie-breaker,” Medvedev said. “I’m really happy with my level of play.” Next up for Medvedev will be 122nd-ranked German lucky loser Peter Gojowczyk, who outlasted British 13th seed Kyle Edmund 6-3, 4-6, 6-3. Gojowczyk, who only made the event after Australian Bernard Tomic dropped out with a finger injury, won his only title in 2017 at Metz. In the accompanying WTA event, Taiwan’s 31st-ranked Hsieh Su-Wei lost to Catherine McNally 6-4, 6-3.
