Murray wary of Tomic threat

Andy Murray is wary of Bernard Tomic's unpredictability ahead of their second-round clash at the Miami Masters.

Tomic knocked out Frenchman Marc Gicquel 7-5 7-6 (7-3) in the first round to earn a shot at Murray, who as second seed in Florida was given a bye through to the second round.

They pair have only met once before, in Brisbane last year, and Murray hammered the combustible Tomic 6-3 6-2.

Tomic, 6'5, is one of the most frustrating players on the tour - unplayable one day, appalling the next. His on-court and off-court behaviour makes headlines as often as his victories, and he is generally regarded as a much better player that his current world ranking of 45 suggests.

Murray admits it is hard to know which Tomic will turn up in Miami on Saturday.

"I'll see, obviously, when I play against him. I haven't seen him play that much outside of Australia the last year or so," he said.

"He's a very, very talented player. He makes it tough for everyone. He's got a very unorthodox game."

The conditions are much more to Murray's liking than Indian Wells where he lost to Juan Martin del Potro in the quarter-finals last week.

The Scot admits he struggles in the dry desert heat of California, and is much happier in humid Miami, where he spends his off-season.

"I think it should help," Murray said. "I have trained in these conditions a lot. I find the conditions quite tricky in Indian Wells - they are extremely different from the conditions from here, where I train and practice."
