Americans will comprise half the semifinals of the Hamburg Open, as No. 6 seed Tommy Paul defeated Germany’s Daniel Altmaier 6-2, 7-5, and lucky loser Aleksandar Kovacevic extended his run in a three-set win over Argentina’s Camilo Ugo Carabelli on Thursday.
One day after upsetting top-seeded Felix Auger-Aliassime of Canada, Kovacevic outlasted Ugo Carabelli 6-4, 6-7 (10), 6-2 in two hours and 43 minutes. The marathon second-set tiebreaker featured Ugo Carabelli saving one match point on his way to forcing the third set. But Kovacevic finished with nine aces and a perfect 7-for-7 mark in saving break points.
Kovacevic will face Peruvian qualifier Ignacio Buse, who topped Frenchman Ugo Humbert 6-3, 5-7, 6-3. Paul, seeking his second tournament title of the year, will square off with Australian third seed Alex de Minaur, who breezed past Italian seventh seed Luciano Darderi 6-0, 6-3.
