Andy Murray says he is in better physical shape entering this year's Wimbledon than he was during his title run at the Championships a year ago.

The defending champion said that he was now "moving well" on grass, having practiced on the surface following his second-round exit at Queen's.

"I’ve practiced with [Jo-Wilfried] Tsonga and [Grigor] Dimitrov, then obviously had a good match here," Murray said at Stoke Park. "I’ve spent a lot of time on the courts and I’m feeling good."

At Queen's, Murray pointed out that his best performances on grass have been during longer periods of play on the surface, like his 2012 grass-court season, which included reaching the Wimbledon final and winning the Olympics. He also had more time to prepare a year ago after withdrawing from the French Open with a back injury.

The 27-year-old underwent surgery following the U.S. Open and says there has been an improvement in his condition.

"Now I’m just happy to not have to worry about it on a daily basis," Murray said. "It’s something I have to always monitor throughout my career and look after but I’m not waking up in the morning worrying about how I’m going to feel. That was the case for a while before surgery."

Murray, who snapped a 77-year British drought in the Wimbledon men's singles with his victory, is the third seed at this year's Championships.
