Matteo Berrettini exits Wimbledon after testing positive for the coronavirus.

WIMBLEDON, England — Matteo Berrettini, a finalist at Wimbledon last year, withdrew from this year’s tournament on Tuesday after testing positive for the coronavirus.

Berrettini’s announcement of his withdrawal came only about two hours before he was to take to the court for his first-round match against Cristian Garin and was the latest blow to a Grand Slam tournament that was already shorter than usual on stars and has been stripped of ranking points for this edition by the men’s and women’s tours.

Berrettini, who was undefeated on grass courts this season and seeded No. 8 at Wimbledon, was one of the leading contenders for the men’s singles title. His withdrawal came one day after another player, Marin Cilic, the No. 14 seed from Croatia and a 2017 Wimbledon finalist, also withdrew after testing positive.
