Andy Murray maintained his record of never having lost before the third round at Wimbledon with a 6-3 6-3 7-5 victory over Tobias Kamke on Court One yesterday.

The 24-year-old stamped his authority on the second-round match from the off and cruised through the first two sets before Kamke made a contest of it in the third.

However, the German eventually cracked and Murray served out for victory, to set up a meeting with Ivan Ljubicic tomorrow.

The fourth seed felt there was room for improvement, saying: "I served well. The rest of it is going to need some work. It was quite tricky with the wind and he was hitting the ball really hard and flat, which made it difficult to get into a rhythm.

"I felt like I was a little upright, I didn't move that well. It was a good workout for me and I'm glad to get through in straight sets."

The home hope had given his supporters a scare by losing the opening set of his first-round clash to Daniel Gimeno-Traver but he could not have made a better start yesterday.

As if Kamke was not a big enough underdog, the German had to contend with an overrule on his first serve and then a tumble before two double-faults handed Murray a break.

Murray had a couple of chances to break early in the second set but could not take them, and he dug himself out of a hole of his own making in the seventh game after a double fault handed his opponent a first break point.

Kamke was made to regret that missed opportunity later when he fired a forehand wide to hand the Scot a break, and some big serving helped him move two sets in front.
