Marc Warren, Branden Grace, Emiliano Grillo and Bernd Wiesberger share the lead after the third round of the Qatar Masters.
The quartet sit 13-under, with Warren leading the charge after he suffered just one blemish on a six-birdie round in Doha.
Grace hit two bogeys on the third and fourth holes, but recovered with five birdies, while Grillo ended his day without dropping a shot.
Wiesberger suffered a bogey on the 16th, but he moved himself two shots above the rest of the pack, as Eddie Pepperell, Alejandro Canizares and George Coetzee remain the closest challengers to the top four ahead of the final day.
Justin Rose sits seven shots off the pace after carding a third-round 69 following a first-hole double bogey.
