Dimitrov comes through marathon clash with Donaldson

Grigor Dimitrov came through a gruelling encounter with Jared Donaldson to progress to round three

Fourth seed Grigor Dimitrov clinched a marathon 6-7 (2/7), 6-4, 4-6, 6-4, 10-8 victory over American Jared Donaldson to book a last-32 spot at Roland Garros on Wednesday.

The Bulgarian was pushed all the way by world number 57 Donaldson in a match that lasted four hours and 19 minutes, but grabbed the crucial break in the 17th game of the deciding set as his opponent started to struggle with cramp.

Dimitrov will face dangerous Spaniard Fernando Verdasco next as he looks to reach the fourth round in Paris for the first time.
