Motherwell closed to within six points of Scottish Premier League leaders Rangers despite being held to a goalless draw by Kilmarnock.
Motherwell started brightly, with Kilmarnock goalkeeper Anssi Jaakkola denying Stephen Craigan and Chris Humphrey before watching helplessly as a Tom Hateley corner struck the crossbar.
Gary Harkins sent a drive against Motherwell's post and Manuel Pascali found the net with a header from a corner just before the break but the defender was adjudged to have fouled in the build-up.
Jaakkola saved well after the break from Steve Jennings and Michael Higdon, as Motherwell were denied a fourth successive win.
Hibs clinch St Mirren thriller
Hibernian, meanwhile, took all three points as they came out on top in a 3-2 thriller against St Mirren. Hibernian took the lead early on as a mistake from St Mirren goalkeeper Craig Samson allowed Leigh Griffiths to steal the ball off him and score his first goal for the Easter Road club.
However, two goals in two minutes from McGowan gave St Mirren the lead as he first headed home a David van Zanten cross before getting on the end of a Steven Thompson knock-down to drive home his second.
St Mirren held the lead for just five minutes though, as Sean O'Hanlon got on the end of a David Wotherspoon free-kick to send a header sailing past Samson.
Hibernian then restored their lead just before half-time when Garry O'Connor sent the ball up-field to strike partner Griffiths, who drove an angled shot past Samson for his second of the game. Despite sustained pressure from St Mirren in the second half, Hibs held on to claim the three points.
Dunfermline frustrate Inverness
Dunfermline scored a late penalty to record a 1-1 draw that leaves Inverness Caledonian Thistle rooted to the bottom of the table.
Gregory Tade gave Inverness the lead in the 33rd minute when he headed in Richie Foran's cross. And Inverness looked set to leapfrog Dunfermline at the bottom of the table before David Proctor conceded a late penalty that substitute Liam Buchanan converted minutes before the end.
St Johnstone started life without manager Derek McInnes with a goalless draw away to Dundee United that kept the Saints in fourth spot. Rangers are away to Hearts in Sunday's early kick-off match, while Celtic host Aberdeen at Parkhead.
