Inverness kept the deficit on Celtic to five points after a 1-0 home victory over St Johnstone.

A close-range effort from Billy McKay decided the contest after four minutes, as both teams cancelled each other out in the remainder of the game.

The score was McKay's 10th league goal of the season and ensured he would remain at the top of the Premiership's goalscoring charts.

Motherwell remainwithin touching distance in third place after a 2-0 win away to Kilmarnock. Strikers John Sutton and Henri Anier were on target in the 55th and 88th minutes respectively, to take their tally to 11 league goals between them.

The result leaves Kilmarnock in the relegation play-off places and above only Hearts, who required a last-minute strike from Ryan Stevenson to earn a 2-2 draw at home to 10-man Ross County.

Melvin De Leeuw put the visitors ahead for a second time in the opening stages of the second half after Graham Carey's 23rd-minute strike was cancelled out almost straight away by Callum Paterson.

The Staggies were reduced to 10 men when captain Richard Brittain was shown a second yellow card and Stevenson equalised with two minutes of the game remaining. David Smith's cross was layed off by Danny Wilson and the forward forced the ball home from inside a congested six-yard box.

The drama was not over, however, as Paterson crashed a header off the bar from a Smith free-kick.

Two Gary Mackay-Steven goals helped Dundee United to a 4-1 defeat of nine-man Partick Thistle.

Jackie McNamara's men won the contest at a canter, with further goals coming from Andrew Robertson and Brian Graham, after Aaron Muirhead had scored from the penalty spot in the 57th minute for Partick, who had Conrad Balatoni and Stuart Bannigan sent off.

In the lunchtime kick-off, Terry Butcher enjoyed a positive start to his Hibernian reign with a 0-0 draw in his first match in charge at St Mirren.

The new Easter Road manager may not have had a win to celebrate at the end of the goalless Scottish Premiership encounter at St Mirren Park, but he would have taken some satisfaction from ending a run of four straight defeats endured by the Edinburgh side before he took over the job at Hibs.
