Murray storms into French Open last eight

Paris: Second seed Andy Murray reached the French Open quarter-finals for the sixth time on Sunday with a 7-6 (11/9), 6-4, 6-3 win over John Isner of the United States.

Murray, a three-time semi-finalist in Paris, will face either Japan's Kei Nishikori or Richard Gasquet, the last French player standing, in the last-eight.

It will be 29-year-old Murray's 20th appearance in the quarter-finals of the last 21 majors after braving an Isner storm in the first set where he faced down three set points in the tie-breaker.

"It was a very important tie-break to win. I got lucky on his first set point when I guessed right on a short forehand," said Murray.

Isner was bidding to become the first American man in the last-eight in Paris since Andre Agassi in 2003.

Having not allowed Murray a single break point, the 31-year-old squandered three set points in the breaker before the British star pounced to pocket the opener.

Rain forced the pair off Suzanne Lenglen court for an hour with Murray 2-1 ahead in the second set before Isner was broken for the first time in the 10th game which allowed the world number two to take the set.

Murray broke for 3-1 in the third before Isner just clung on saving two more break points in the sixth game.

The world number two wrapped up victory -- and his sixth win in six clashes with the big American -- with his ninth ace of the tie.

Isner, meanwhile, was undone by Murray's superior returning which contributed to his 57 unforced errors.
