Murray wary of Dimitrov threat

Andy Murray will take nothing for granted when he faces Grigor Dimitrov in the third round of the Miami Open next week.

The Scot eased past Denis Istomin in straight sets earlier on Sunday, but now faces a tougher assignment against the Bulgarian.

“Dimitrov is obviously a top-quality player,” the 28-year-old told

“He had a good win today, a tough win, against [Federico] Delbonis. We played here once before; I managed to win that one. I played a bunch of tough matches against him. I think the last one was in Cincinnati where he had a match point.

“He had a bunch of chances to win that one and I managed to turn it around. I know I’ll need to play good tennis and be a little bit more disciplined than I was tonight.”

A little-known Dimitrov memorably knocked out Murray in the quarter-finals of Wimbledon in 2014, but the two-time grand slam winner has defeated him three times since.

Murray added that he was happy the way he was striking the ball in the Miami heat, but perhaps needs to make better decisions when it comes to shot selection.

“When you’re break points down and trying drop shots or going for big shots from the wrong position, it makes it tough,” said the world number two.

“But I was hitting the ball cleanly. It’s just the shot selection tonight could have been better, I think.”
