Easy progress for Murray

Andy Murray was given an easy ride into the French Open fourth round after opponent Janko Tipsarevic retired injured.

The Scot had just taken the second set to grab a 7/6 (7/3) 6-3 lead when Tipsarevic gestured the match was over, strode to the net and shook hands with his opponent on the Suzanne Lenglen court.

Murray therefore progresses to the last-16 stage for the first time at Roland Garros, where he will play 13th seed Marin Cilic.

The players started off in the baking heat and Murray struggled early on.

He was broken for the first time in the fifth game when he sliced a backhand into the net on the second on Tipsarevic's break points.

The Scot wasted two break-back opportunities in the next and then found himself 5-2 down when the Serbian flashed a forehand past him, after a poor Murray approach shot, to break again in game seven.

Tipsarevic then got sloppy as Murray broke and then held, forcing the Serb to serve out the set. He had two chances to do so but he wasted both of them, and a sloppy forehand long handed Murray another break to make it 5-5.

The pair were both then broken again to take the set it a tie-break.

Murray went 5-3 up and after Tipsarevic sent a backhand wide, Murray emerged triumphant from a lengthy rally on set point to take it 7-3.

Tipsarevic received treatment on his left thigh on the first changeover in the second set, after Murray had broken to go 1-0 up.

The Serb continued - and even went on to break back immediately - but it was clear he was not moving freely by that early stage.

The medics came out again after Tipsarevic had smashed a forehand wide to gift a second break to Murray.

The Scot was now full of confidence and was taking advantage of his opponent's lack of movement, a clever drop-shot putting him 4-2 up.

Tipsarevic, 24, was grimacing at the end of each rally and although he was refusing to give in, Murray was comfortably in charge.

Serving 3-5 down, the world number 24 saw a backhand flash past him to lose the set. He quit immediately, ushering Murray into round four.
