Roger Federer succumbs to injury and Grigor Dimitrov as he crashes out of US Open
Roger Federer is out of the US Open after he succumbed to both injury and Grigor Dimitrov in the quarter-finals.
Dimitrov, a former world number three, rolled back the years on Arthur Ashe to go toe-to-toe with Federer, eventually winning 3-6, 6-4, 3-6, 6-4, 6-2.
However, the real story emerged after the conclusion of the fourth set, when Federer called for the physio and then, unusually, left court for a medical timeout.
When he returned, he was clearly impeded, with his movement looking especially laboured.
He finished the match, but looked to be going through the motions more than anything before eventually losing the match.

For Dimitrov, it was a first career win over Federer, and will be an emormous boost as he looks to rebuild a world ranking that has taken a battering over the last two years.
He will now face fifth-seed Daniil Medvedev in the semi-final – the third of Grand Slam semi of his career.
