Leaders Queen of the South remain unbeaten in the Championship after a frustrating day in Dumbarton.
The visitors struggled to find a cutting edge without top goalscorer Derek Lyle, who picked up a thigh injury in the warm up.
Dumbarton's Robert Thomson's clipped the post with a header and Darren Barr missed a close-range chance.
The hosts threaten again after the interval when Sam Stanton drove a shot into the side-netting.
The Dumfries side had been averaging two goals a game in the league but found openings hard to come by.
Josh Todd had the first sight of goal for Dumbarton in the eighth minute when he won the ball in midfield and drove forward but dragged his effort wide.
Stephen Dobbie teed up Kyle Jacobs but his shot was narrowly wide before the former saw his shot blocked and Steven Rigg pulled the rebound wide.
After Thomson grazed the woodwork Barr should have put the hosts ahead but put the ball over the crossbar after a long throw from Daniel Harvie caused havoc in the Queens box.
Dobbie curled an early shot wide in the second half before Alan Martin had to be sharp to stop Rigg's header.
Lyndon Dykes then sent another header wide for Queens as both sides had to settle for a point.
