Match ends, St. Mirren 0, Motherwell 2.
St Mirren have now gone 10 Scottish Premiership games without a win after they were swatted aside by Motherwell.
Goals from David Turnbull and Chris Cadden ended a run of five games without a win for the Fir Park side.
The defeat in Paisley consigns St Mirren to a sixth straight Premiership loss and keeps them second bottom, a point clear of Dundee.
Oran Kearney's side also had Ryan Flynn sent off in the second-half for a terrible tackle on Richard Tait.
The win moves Motherwell up to ninth - one place, but seven points, behind Aberdeen.
Nothing to grasp at for hapless St Mirren
This should have been the game Kearney was waiting for. Six games in the job, the Northern Irishman has yet to win one of them, five defeats from the last five offering a bleak backdrop in Paisley.
However, against a Motherwell team with just one victory in the Premiership and severely lacking in confidence, a glaring opportunity was there to be grasped. In the end, there was nothing to clutch at for Kearney here.
A back three was put in place with an overloaded midfield to try and go toe-to-toe with Motherwell, but the challenge was meek. In defence they were hapless, midfield lost, and non-existent in attack. They were picked off and bullied with ease.
The warning signs were clear early on. A one-two between Liam Grimshaw and Cadden opened up a chasm for the latter to surge through. His drilled cross was then missed by Paul McGinn, only for Curtis Main to let them off the hook.
When the first goal did come, unsurprisingly for the visitors, it was met with stunned silence. A firm but routine shot from Turnbull was let off in the direction of Samson 20 yards out, but the former Motherwell keeper inexplicably allowed the ball to skid under him, as "One Craig Samson" chants emanated from the away end.
A response was needed after the break ahead of a huge 45 minutes for the Paisley side, but they bounced like a breezeblock.
Within two minutes, Cadden again pierced the St Mirren defence with a one-two, but this time Main's return laid the ball perfectly for the winger to curl a low shot beyond Samson from the edge of the box.
There was still plenty time for matters to deteriorate for Kearney. The frustration of the crowd was channelled by Flynn, who scythed down Tait as he rampaged down the left. As the red mist descended, and a red card was raised.
Motherwell deliver while Buddies abysmal - analysis
That's now six defeats in a row for St Mirren, with only two goals scored. Things don't get any easier for Kearney, whose side welcome Rangers on Saturday as the severity of the Paisley side's situation only intensifies.
As poor as Dundee are, St Mirren were abysmal when so much was there for them to take. That draw with Celtic in Kearney's first game in charge is a fading memory.
Motherwell, on the other hand, have delivered what St Mirren simply could not - a performance when it was so badly needed.
The Fir Park club have squandered four leads this season but it never looked likely here. Defeat could have seen them slip to second bottom. Instead, a victory over a beleaguered Dundee on Saturday and Stephen Robinson and his team can, perhaps, begin to lift their heads and gaze upwards.
'We just lacked quality' - reaction
St Mirren manager Oran Kearney: "There's certain things you can ask for and things you can try and get but I think in areas of the pitch we just lacked quality and that's probably the harshest part of it all.
"Fans will go away from that tonight and say that's as poor a performance as we've had but actually I think our players were braver tonight."
Motherwell manager Stephen Robinson: "I never lost belief in any of the players. I get a bit of stick for having some loyalty to a lot of the guys but I know the character we have in the team is always there. It's just trying to get them to believe.
"I try and take the stick, rather than the players. You've got to remember that they're young boys who aren't on millions of pounds. They make mistakes and their decision-making at times can be better."
