World No.4 Andy Murray moved into the second round of the Australian Open to meetFrench man Edouard Roger-Vasselin on Thursday. In the first round on January 17, he defeated American teenager Ryan Harrison.

The 19-year-old Harrison displayed some excellent forehands and second serve to clinch the first set 4-6.

In the first set Murray looked a bit slower than usual. He finished the set with a count of 17 unforced errors.

Murray managed to win 4-6, 6-3, 6-4, 6-2 in three hours and 12 minutes on a humid afternoon.

"I thought he was good. He serves well. He's quick. He does everything pretty solid. There wasn't one thing in particular that was incredible, but there weren't too many holes in his game, which, you know, if you want to be a good player, you can't have any," Murray spoke about his American opponent in a post-match interview.

The 24-year-old Scot is expected to put up a good show as he meets the French man in the next round. He has a good record against French players.

World No. 1 seed Novak Djokovic who defeated Murray in the final 2011, needed only 92 minutes to beat Italian Paolo Lorenzi 6-2 6-0 6-0 in the first round.
