Martina Hingis’ Olympic return is off to a rough start, and the Games are still nine days away.
Hingis, the five-time Grand Slam singles champion who is set to go 20 years between Olympic appearances, has lost her slated doubles and mixed doubles partners on consecutive days. Hingis is not playing singles in Rio.
Belinda Bencic became the fourth female tennis player ranked in the top 20, and the second Swiss player of either gender in as many days, to withdraw from the Olympics on Wednesday.
Bencic, a 19-year-old ranked No. 16, is behind in training following a wrist injury suffered at Wimbledon last month, according to her social media.
On Tuesday, Roger Federer withdrew from the Olympics, citing a knee injury.
Whether Hingis will play with another partner hasn’t been announced.
