Jannik Sinner has advanced to the Wimbledon quarterfinals despite hurting his right elbow on a fall and dropping the first two sets, because his opponent, Grigor Dimitrov, had to quit with an injured pectoral muscle.

Dimitrov was playing fantastic tennis, running Sinner around the court and delivering booming serves. Dimitrov won the first set 6-3 and survived a hard-charging comeback attempt from the Italian in the second to take the set 7-5 and put the world No. 1 in a desperate position.

The top-seeded Italian, dealing with an apparent arm injury, had dropped the first two sets to Grigor Dimitrov before the Bulgarian was forced to retire because of injury.
