A devastated Grigor Dimitrov retires injured when two sets up on world number one Jannik Sinner in the Wimbledon fourth round.

Jannik Sinner has advanced to the Wimbledon quarterfinals despite hurting his right elbow on a fall and dropping the first two sets.

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.
