Match ends, St. Mirren 0, Dundee United 0.
Manager Jim Goodwin was pleased but frustrated as his St Mirren side's search for a first Scottish Premiership win of the season continued after a stalemate with Dundee United.
The Paisley side are now five without victory, with only Livingston and Ross County below them in the division.
Goodwin was left aggrieved after Eamonn Brophy had an effort ruled out when Curtis Main was penalised for a push.
"I thought we had a decent goal chopped off," he said.
"People will say Curtis was grappling with the defender, and he is, but the defender was also grappling with Curtis. He's got too much strength for him and it's a brilliant finish from Brophy.
"And that's the fine margins we're playing to unfortunately. On another day that goal might stand and we're standing here with three points instead of one."
Both sides went close to finding a winner, with the home side's Richard Tait having an effort well saved, and United's Marc McNulty hitting a post.
The visitors - who remain in seventh - might be left to rue injuries that forced off defenders Liam Smith and Ryan Edwards.
Goodwin gave 16-year-old Dylan Reid his first start, while Australian right-back Matt Millar and Wolves loanee Connor Ronan made their debuts.
But as the first half wore on, the hosts began to look the more likely to be cut open, with Peter Pawlett at the centre of most of United's good play.
The midfielder drove down the left and knocked the ball to Ian Harkes, whose shot was saved but deflected towards goal, and defender Joe Shaughnessy had to be alert to head it off the line.
Then Pawlett played a one-two with Harkes to open up space for himself, but blasted over with the goal gaping.
Brophy volleyed the ball into the net from close range for St Mirren after the break, but the referee ruled it out and penalised Main for a foul in the build-up.
Main headed over a minute later, while at the other end Louis Appere broke clear and forced Jak Alnwick into a save.
And then United really should have taken the lead when McNulty burst through but he delayed his shot then eventually clipped it off the outside of a post.
The hosts were finishing the stronger, though, and it took a brilliant save from United goalkeeper Trevor Carson to keep the scores level when he palmed over Tait's powerful effort.
Man of the match - Eamonn Brophy
What did we learn?
Goodwin made a bold call by starting 16-year-old midfielder Reid, but the youngster looked composed. His side have scored just three goals in five league games, though, and another blank in front of goal will worry the manager.
United too often this season have passed up gilt-edged chances and they did the same in this one, with Pawlett and McNulty in particular failing to hit the target.
That lack of clinical edge cost them a point against Hearts before the international break, and three points in Paisley.
What did they say?
St Mirren manager Jim Goodwin: "I'm a little frustrated, but I've got to be happy with another clean sheet - that's two back-to-back against good opposition [St Johnstone and Dundee United].
"People may look at the result and see a boring 0-0 but I don't think for the fans here it was that way. I thought it was a decent game with two attacking teams."
Dundee United manager Thomas Courts: "We certainly created a lot of good chances and had some good combination play. We inherited a team that didn't create a lot of chances last year so it's a bit of a breakthrough for us.
"Hopefully the killer instinct is the next part for our team."
St Mirren are next in action on Saturday away to Hibernian (15:00 BST), while United face city neighbours Dundee in their first derby meeting of the season on Sunday 19 September (12:00).
