Henri Anier and Lionel Ainsworth were on target as Motherwell racked up their biggest win of the season against St Mirren.
Stuart McCall went with the same starting 11 which ended ’Well’s mini slump the week before at Ross County.
There were mere seconds on the clock when Anier went close for the first time from Ainsworth’s cross to the near post.
Steven Thompson and John Sutton then traded headers wide, before the home side took the lead on 31 minutes.
ANIER jinked into the box before tying St Mirren captain Jim Goodwin in knots and firing past Marian Kello.
A minute later Sutton played in Ainsworth, but his shot went across the face of goal.
However, three minutes from half-time the on-loan Rotherham man did find net.
Anier found AINSWORTH who played a give and go with Sutton before having plenty of time to slot beyond Kello.
For the second week running ’Well went in at the break two goals to the good, but while they were left to hang on against a Ross County onslaught seven days previously, this time victory would prove more straightforward.
A mix-up in the visitors’ defence almost gifted ’Well a third as Darren McGregor headed away an Ainsworth worth, leaving Kello, who had come for the ball, in no man’s land.
The ball fell to Sutton at the edge of the box and he struck for goal, but Lee Mair got back to clear.
Anier then swept in from the right, but with Sutton screaming for a square pass he elected to shoot and Kello was comfortable at his near post.
Dan Twardzik started his second game since arriving on loan from Dundee and he was asked to pulled off his first save just after the hour mark as a fierce John McGinn shot stung his palms.
However, any thoughts the Buddies might get back in the game were put to rest on 63 minutes as Iain Vigurs swept in a delicious ball from the left and ANIER poked in.
The Estonian was then taken off to a rousing reception from the Fir Park faithful.
The result could have been even more emphatic, but Kello puled off a good stop to deny Stuart Carswell in injury time.
