WIMBLEDON, England (AP) — Andy Murray beat Ivan Ljubicic 6-4, 4-6, 6-1, 7-6 (4) under the Centre Court roof Friday to reach the fourth round at Wimbledon.

Murray was erratic at the start and end of the match and dropped the second set against the unseeded Croat.

The fourth-seeded Briton picked up his game in the third set and when he led by a break in the fourth, he felt confident enough to flick a winner between his legs in the seventh game.

He was visibly annoyed when he failed to serve out the match at 5-4, but came through the tiebreaker, winning on his second match point.
