Tomic offers tame response to Murray

World No 3 Murray clinched two breaks of serve in each set en route to a 6-3 6-1 victory against an out-of-sorts Bernard Tomic.

The 20-year-old Australian has undoubted potential and has been touted for a bright future but, after a solid start, he offered next to nothing and by the end was barely running for the ball.

Murray, benefiting from his winter training camp in Florida, said: “I just tried to make loads of balls. I don’t know if he was tired or struggling with the humidity, but he was playing pretty low percentage tennis. With the conditions like they were, that played into my hands.

“I think both of us obviously play with quite a lot of variation and there are definitely some similarities. He probably hits the ball flatter than me off both sides and can probably generate more power. But I probably move a bit better than him.”

Jo-Wilfried Tsonga toiled to a straight-sets victory over Victor Troicki in difficult conditions to advance to the third round.

In rising heat and with a blustery wind unsettling both players, the sixth seed prevailed 7-6 (8/6) 6-3.

Andreas Seppi, 16th seed, came through a strength-sapping match to beat Aljaz Bedene 7-5 5-7 7-5 while Sam Querrey, seeded 17th and playing his first match as the top-ranked American, came from a set down to beat Poland’s Lukasz Kubot 4-6 6-3 6-3.

In the women’s third round, seventh seed Petra Kvitova and ninth seed Caroline Wozniacki were knocked out, while Venus Williams pulled out of the tournament citing a lower back injury –following world No 3 Victoria Azarenka, who withdrew on Friday due to an ankle problem.

Three-time Miami winner Williams, 32, withdrew shortly before her match with fellow American Sloane Stephens, meaning the 16th seed advanced by walkover.

Belgian 30th seed Kirsten Flipken saw off 2011 Wimbledon champion Kvitova 6-0 4-6 6-1, and former world No 1 Wozniacki was beaten 6-2 6-4 by world number 73 Garbine Muguruza.

Venus’s sister Serena Williams, the top seed, was a 6-3 6-3 winner against Japan’s Ayumi Morita.
