Scottish Premiership Review: Motherwell thrash fellow strugglers St Mirren, Ross County win

A 5-0 thrashing at Motherwell left St Mirren staring at Scottish Premiership relegation, while Ross County beat St Johnstone 1-0.

Motherwell demolished bottom-of-the-table St Mirren 5-0 to leave their opponents' Scottish Premiership survival prospects looking increasingly remote.

Lee Erwin blasted home a pair of emphatic left-footed strikes set up by Lionel Ainsworth to give the hosts a clear advantage and the game was virtually over as a contest when Scott McDonald converted from close range on the stroke of half-time.

John Sutton got in on the act with his own double during the second half, concluding a damaging evening for Gary Teale's St Mirren, who are now 10 points behind Motherwell in 11th following a fourth consecutive loss.

Ross County are three points better off than Motherwell in 10th after securing a vital victory of their own, 1-0 at home to St Johnstone.

A tense encounter was settled when Liam Boyce headed home Jamie Reckord's cross six minutes from time, extending County's remarkable resurgence to seven wins in an eight-match unbeaten run.
