Grigor Dimitrov was in full control on Monday with a chance for one of the biggest upsets at Wimbledon. But a pectoral injury ended his day early, and he was forced to retire while holding a two-set lead over No.

Jannik Sinner is through to the Wimbledon quarterfinals, though not in the way he wanted. Sinner lost the first two sets of his fourth-round match with Grigor Dimitrov on Monday before Dimitrov was forced to retire from the match after suffering an apparent pectoral injury.
