Canada’s Felix Auger-Aliassime rallied for a 4-6, 7-6 (2), 7-6 (4) victory over qualifier Egor Gerasimov of Belarus in the second round of the Cologne Championship on Wednesday.
The fifth-seeded Auger-Aliassime, who received a first-round bye, broke Gerasimov when the world No. 87 was serving for the match up 6-5 in the second set at the ATP Tour 250 hard-court event.
Auger-Aliassime, ranked 22nd in the world, is coming off a run to the final last week at the Cologne Indoors.
The Montreal native struggled on second serve Wednesday, winning only 51 per cent of those points, but he saved six-of-10 break points.
In the quarterfinals, Auger-Aliassime will face the winner of a match between Jan-Lennard Struff of Germany and Yoshihito Nishioka of Japan.
No. 3 seed Denis Shapovalov of Richmond Hill, Ont., will play a second-round match on Thursday against Gilles Simon of France.
Also Wednesday, top-seeded Alexander Zverev overcame Australia’s John Millman 6-0, 3-6, 6-3.
Zverev hit 10 double-faults but held his nerve to win his fifth straight match in Cologne after winning last week’s Cologne Indoors.
The two back-to-back competitions were added to the provisional schedule following the suspension of the season due to the coronavirus pandemic.
Zverev next faces eighth-seeded Adrian Mannarino, who beat Serbia’s Miomir Kecmanovic 6-3, 6-3.
Also, Spain’s Alejandro Davidovich Fokina beat Steve Johnson of the United States 7-6 (3), 6-3 in the second round.
