Steven Naismith’s first half goal decided a tight encounter at Fir Park as Motherwell suffered a 1-0 defeat against Hearts.
Stephen Robinson named an unchanged side from the 3-1 victory over Dundee two weeks ago, as the Steelmen looked to follow up on a first league win.
Despite a hugely positive opening half, where Curtis Main went close with a volley and Richard Tait was denied from close range, Hearts took the lead against the run of play.
Uche Impeazu latched on to a Carl McHugh back pass, colliding with Trevor Carson, before Naismith picked up the loose ball and passed the ball home.
It left the Fir Park side a goal down, but also forced an early change as Carson was stretchered off with a painful injury to his ankle.
The second half was a largely frustrating one for Robinson’s men, with all substitutions used after just 60-minutes, Hearts sat in and looked to hold on to their lead.
And despite McHugh’s best efforts to nod home a Gaël Bigirimana cross, the visitors held on to maintain their perfect start to the Premiership campaign.
