Marc Warren pulled off what he described as the 'shot of his career' to move into fourth place, but only one shot off the lead after two rounds of the Commercial Bank Qatar Masters.

Warren muscled his way towards a fourth Tour success, in posting a seven-under-par 65 in ideal scoring conditions on the Doha Golf Club course in Abu Dhabi.

Austrian Bernd Wiesberger (66) and the South African pair of George Coetzee (67) and Branden Grace (68) share the lead on nine-under.

Warren is tied with Korean Byeong-hun An (69) and Argentina's Emiliano Grillo (69).

The Scot began his round from the 10th and made the turn in two-under with three birdies and a bogey.

The current world No.71 then ignited the fireworks by making eagle the par-five first hole.

He said: "That three-wood shot of 279 yards and probably my limit with the club, was probably the best shot I've ever hit in my career.

"I made a few birdies over my front nine, but that eagle to start my back nine was a real momentum changer as I then played the inward half in 31 and five-under thanks also to four birdies and just one bogey.

"My best shot prior to the eagle today was in winning the 2006 Scandinavian Masters when I remember having to carry a 267-yard shot from off the deck on to the green down the last hole to win my first Tour event."

The Callaway 3-wood, despite sporting a new shaft, was the same club Warren used to capture last year's Made in Denmark title.

Paul Lawrie birdied his opening hole, but was left ruing a second-hole double bogey in a score of 73 to drop to four-under.

Scott Jamieson was left lamenting a poor last few holes after moving to seven-under through 13 holes, but then playing the last five in four- over that included a 17th-hole double bogey.

And Scotland's top-ranked Stephen Gallacher will play all four rounds - despite a 75 - to make the cut right on the one-under mark.
