Serbian Laslo Djere defeated titleholder Lorenzo Musetti of Italy to reach the semi-finals of the ATP Hamburg Open on Friday.

World number 57 Djere won in straight sets 7-5, 6-3 against the 2022 Hamburg Open winner and third seed, who came into the match as the favourite.

The 28-year-old, who has won two previous titles on clay, will face the winner of China's Zhang Zhizhen and German Daniel Altmaier in Saturday's semi-final.

In the other half of the draw, Hamburg-born fourth-seed Alexander Zverev faces Luca Van Assche while top seed Casper Ruud takes on Arthur Fils.
