Drama and upsets mark the early rounds of the Terra Wortmann Open in Halle, one of the key ATP 500 grass-court events ahead of Wimbledon. In the round of 32, Alexander Zverev delivered a clinical performance, dispatching American Marcos Giron 6-2 6-1. Karen Khachanov also advanced comfortably, beating Belgium’s Zizou Bergs 7-5 6-3.
The real surprise came as the round of 16 got underway. Stefanos Tsitsipas, a top seed in the draw, was knocked out by American youngster Alex Michelsen in straight sets, 7-6(5) 7-5. The match was tightly contested, but the 19-year-old held his nerve in the key moments to claim a statement win.
There were no such troubles for Daniil Medvedev, who eased past Quentin Halys 6-2 7-5 to book his place in the quarterfinals.
Up next, Lorenzo Sonego will take on home favourite Zverev, while Jannik Sinner is set to face off against the unpredictable Alexander Bublik.
