Motherwell had debutant Lee Erwin to thank for all three points as his goal defeated St Mirren at Fir Park.
The Buddies dominated the first half, but none of their efforts troubled Well goalkeeper Dan Twardzik.
However, it was Motherwell who took the lead when Erwin pounced in the box to bundle the ball home.
And the game swung further in the hosts' favour when St Mirren's Jim Goodwin was shown a second yellow card for dissent, resulting his dismissal.
