Canada’s Auger-Aliassime retires with knee injury at Shanghai Masters

Shanghai, Russia - Daniil Medvedev secured a spot in the quarter-finals of the Shanghai Masters on Wednesday, defeating Stefanos Tsitsipas in straight sets 6-4, 7-5. The Russian 30-year-old did not face a single break point during his victory over the 28-year-old Greek tennis star. Medvedev, the fifth seed, expressed satisfaction with his performance, stating that he managed to apply pressure on Tsitsipas in the first set.

The second set was a different story, described by Medvedev as "very tight." The match concluded in one hour and 24 minutes.

This was the sixteenth time Medvedev and Tsitsipas faced off on the Tour, with Medvedev currently leading their head-to-head record with 11 wins. Medvedev won the Shanghai Masters in 2019. Before Wednesday's match, rising Spanish star Rafael Jodar had also advanced to the quarter-finals, defeating Botic van de Zandschulp 6-7 (4/7), 6-4, 6-2.

Jodar received a code violation in the second set for swearing at a ball boy in Spanish while requesting a towel. He will face Casper Ruud in the next round. Fourth-seeded Felix Auger-Aliassime suffered an injury during his match against Tommy Paul, retreating due to pain in his left knee. Ruud, ranked 24th, noted that Auger-Aliassime's trouble seemed to begin in the fourth game of the first set.

Auger-Aliassime required a medical timeout after the fifth game, starting the next game down 1-4 with a white strapping around his left knee.
