Dimitrov, Zverev, Nishikori reach round 3rd at Roland-Garros

Grigor Dimitrov bt Jared Donaldson 6-7 (2/7), 6-4, 4-6, 6-4

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.

Alexander Zverev bt Dusan Lajovic 2-6, 7-5, 4-6, 6-1, 6-2

Alexander Zverev staged a fightback to win a five-setter with Dusan Lajovic.

German world number three Zverev found himself in deep trouble when trailing by two sets to one against Lajovic, but the Serbian ran out of gas as it finished 2-6, 7-5, 4-6, 6-1, 6-2.

The 21-year-old, a winner of three Masters titles, is yet to reach a Grand Slam quarter-final and was knocked out in the first round at Roland Garros last year.

But Zverev moved into round three for the second time, where he will play Bosnian 26th seed Damir Dzumhur, as he looks to become the first German man to win the title since 1937.

Kei Nishikori bt Benoit Paire 6-3, 2-6, 4-6, 6-2, 6-3

Japan's Kei Nishikori also staged a comeback to edge out Frenchman Benoit Paire on Philippe Chatrier court, winning 6-3, 2-6, 4-6, 6-2, 6-3 in his first Grand Slam event since Wimbledon last year after recovering from a wrist injury.
