'Struggling' Murray advances at Open

Andy Murray moved into the fourth round of the Australian Open on Saturday with a straight-sets victory over Lithuanian qualifier Ricardas Berankis that was harder than the scoreline suggested.

The number three seed recorded a 6-3, 6-4, 7-5 win in 2hr 12min, but he trailed by a break of serve in the second set and appeared agitated at various stages, hitting his racquet onto the court and yelling at his courtside box.

Murray served for the match at 5-4 in the third set but Berankis, the world number 110, broke back. But the 22-year-old dropped his next service game and Murray made no mistake in his second attempt at closing the victory.

The Olympic and US Open champion will next face the winner of the all-French affair between Gael Monfils and Gilles Simon, to be played later Saturday.

"I was struggling," Murray said. "He (Berankis) was making me feel pretty frustrated. We know each other well and we have practised together. He was making me feel pretty uncomfortable out there."
