St Mirren and Motherwell had to settle for a 0-0 draw in a feisty Clydesdale Bank Premier League encounter.
The home side had by far the best of the first half and Darren Randolph pulled off a wonderful save to deny Gary Teale after sustained pressure.
However, third-placed Motherwell found their stride after the break and only an incredible stop from St Mirren goalkeeper Craig Samson prevented the visitors from leaving with three points from a bad-tempered clash.
Teale impressed for St Mirren on the right wing and almost fired his side ahead on the half hour mark. Teasing and tormenting Steven Hammell, he cut inside and his deflected shot nearly looped in - with Randolph pulling off a fine stop.
The visitors had offered little in attack but had a strong penalty claim turned down in the 37th minute when Marc McAusland appeared to foul Nicky Law. Referee Craig Charleston waved away the appeals.
Tempers were frayed and Douglas Imrie earned a booking for a challenge on Shaun Hutchinson before the break, much to the disgust of the home fans.
Motherwell began the second half with more purpose and Hutchinson headed over from Hammell's corner seconds after the restart.
That was a let-off for Saints, who then had goalkeeper Samson to thank for keeping the score level in the 50th minute. Michael Higdon met Henrik Ojamaa's cross with a bullet header, but Samson produced a wonderful point-blank stop.
Motherwell were a team transformed after their lacklustre first-half display and continued to press, with Tom Hateley curling a free-kick narrowly wide. St Mirren could not get up the park and Samson was again called into action when he pulled off a fine fingertip save from Ojamaa's curling effort in the closing stages.
There was one final chance for St Mirren when Teale found Paul McGowan at the edge of the box, but he fluffed his shot. Incredibly, Motherwell then raced up the park in injury-time and almost won it when Chris Humphrey's attempted cross crashed off the bar with Samson beaten.
