Murray getting stronger

Defending champion Andy Murray admitted his confidence is growing after he moved effortlessly into the fourth round at Wimbledon.

Murray crushed the improving Roberto Bautista Agut 6-2 6-3 6-2 in just over 90 minutes, and he was even more impressive than his previous wins over David Goffin and Blaz Rola.

His Spanish opponent was in the form of his life and won the grass-court tournament in Holland last week.

"It's good to get it done in straight sets," said Murray.

"He's the best opponent I've played. He's obviously seeded and coming in with confidence from winning a tournament last week.

"It was a step up. There were a few things I could have done better but it's been a good first week. Now I can rest up and be fresh for Monday."

Looking ahead to the tussle with Anderson, who at the age of 28 has reached a career-high 18th place in the world rankings, Murray said: "He's a tough opponent.

"He's made improvements this year. He's a big guy with a big game. I'll have to return well if I want to win."

Murray also launched into a series of jokes about brother Jamie, who was in doubles action at the same time - and was being watched by the Murray clan.

"It's a shame we're on at the same time," he added. "None of my family came to watch me so I'm obviously the number two son.

"My brother's the priority - he's number one son - he's always had the preference, that's why I'm so competitive since I've been a kid, but it's good that we both won."
