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.

Tennis legend Roger Federer looked shell-shocked as a tearful Dimitrov walked over to the chair umpire to shake his hand. Sinner later said: "I don't take this as a win at all, this is just an unfortunate moment for all of us to witness.

The 34-year-old Bulgarian won the first two sets 6-3, 7-5 and was tied with Sinner 2-2 in the third when he went down with the injury.
