Australian Open 2013 Day 2 - in pictures

Andy Murray crushed Robin Haase 6-3, 6-1, 6-3 during an entertaining game of tennis. "It was a good start," Murray said. "Nice to win in straight sets. It took a little while to get used to the breeze. I've come close here a few times, so to finally get a slam [in New York] was great and I'll try to focus on the second part of my career now."
