1ST LEAD: Murray ankle worry after Rotterdam rout of Ancic

Murray ankle worry after Rotterdam rout of Ancic Rotterdam, Netherlands  - Andy Murray dominated Mario Ancic in just over an hour, picking apart the Croatian's game 6-1, 6-2 on Saturday for a place in the final of the ABN-AMRO World Tennis.

The Scot second seed has come good at this edition at the Ahoy centre after losing in the first round on his debut a year ago.

The 21-year-old ranked fourth in the world is in line for a possible second title in as many months this season as he waits for the semi-final between top seed Rafael Nadal and Frenchman Gael Monfils.

But Murray could face a fitness niggle after complaining of problems with his right ankle during the match.

"I know that I felt it about 20 minutes after my match yesterday (quarter-finals). I've iced it and it feels OK now.

"If it's the same later, I guess I'll be fine. But if not, then I'll have to speak to the physio."

The Scot admitted that his game was on fire against Ancic, winner of three of their previous four meetings including two last season.

"I was playing great and Mario was not on his best game. I was hitting the ball well and made very few mistakes," said the winner, now 12-1 this season. "It was tough for him but I'm very happy to come through."

Murray has been quite at home on one of the fastest of the indoor hardcourts, winning all but one of his four matches in straight sets.

He is looking for a tenth career title after lifting five in 2008.

Murray took total control of Ancic from the start, racing away with the opening set in 24 minutes. The Croatian ranked 28th, losing finalist last week at home in Zagreb, managed to temporarily stop the rot as he won the fifth game of the second.

But the Murray juggernaut eventually came through for victory in an hour and a minute.

The second seed advanced on his first match point with a forehand winner deep into the corner. (dpa)
