Defending champion Andy Murray maintained his wining streak and hold over Roger Federer today to charge into the final of the Qatar Open with a 6-7 6-2 6-2 win.

The Scot, who is third seed, frustrated the great Swiss with his tactical nous from the baseline to chalk up his fifth win in six matches against the 13-times grand slam great.

Dunblane-born Murray, who beat world number one Raphael Nadal in his last tournament, will be hoping to retain his title when he takes on American Andy Roddick in the final.
