United defender Mark Connolly heads the ball against Killie counterpart Clevid Dikamona and subsequently screams for a penalty for handball. Referee David Munro waves play on.

Here's your chance to rate the players in all four of today's Premiership matches.

Finally a goal in Perth and it's a deserved one for St Johnstone.

Former Scotland winger Craig Conway drives on the left and crosses low for substitute Stevie May to slide in for his first goal of the season.

Hamilton Academical: Fulton, Hodson, Odoffin, Want, McMann, Winter, Mimnaugh, Trafford, Martin, Callachan, Ogkmpoe.

Substitutes: Gourlay, Hamilton, Templeton, Fjortoft, Moyo, Munro, C Smith, Owolabi, Johnson.

Rangers: McLaughlin, Tavernier, Goldson, Helander, Barisic, Jack, Davis, Hagi, Barker, Kent, Roofe.

Substitutes: McGregor, Bassey, Patterson, Kamara, Stewart, Balogun, Arfield, Morelos, Jones.

With still no goals in Perth, St Johnstone manager Callum Davidson throws on fit-again striker Stevie May in place of Michael O'Halloran to see if he can end the impasse.

Benjamin Siegrist keeps United in it.

A low ball across the face of goal is just behind Nicke Kabamba, who swivels and directs an effort towards the bottom corner. Goalkeeper Siegrist turns the striker's effort around the post.

It's all United here, with Calum Butcher repeatedly threatening. Luke Bolton looking bright too.

Still not much to trouble goalkeeper Danny Rogers, though.

Stuart Kettlewell makes two changes as he rearranges his team to cope with the loss of left-back Carl Tremarco. Defender Josh Reid and winger Josh Mullin come on for striker Billy Mckay and right-back Connor Randall.

County are down to 10 men. Left-back Carl Tremarco, already on a booking for a clumsy challenge in the first half, clips the heels of Nicky Devlin as he runs towards goal and is booked again by John Beaton.

Tremarco looks gutted, clearly feeling there wasn't much contact, but it looked clear-cut.

Much better from United now.

Calum Butcher's effort is blocked and falls to Nicky Clark. The striker touches the ball down brilliantly before blazing over. Maybe he should have hit the target.

St Mirren replaced Kyle McAllister with Cammy MacPherson in midfield before the break and then introduced Dylan Connolly in place of striker Jon Obika at half-time. Now manager Jim Goodwin has been forced into their third change, with centre-half Marcus Fraser hobbling off and recent signing Kristian Dennis coming on.

That goal on the stroke of half-time will have enraged United head coach Micky Mellon. He's made a change in midfield to try to get his side back into the game.

Peter Pawlett goes off, Louis Appere comes on.

A second goal on the stroke of half-time has changed the complexion of this game.

It took a wonderful ball in from Calum Waters to unlock the United defence, who have looked solid for the most part. Nicke Kabamba still had a lot to do and headed the ball into the net emphatically.

United have struggled to create chances, failing to register a shot on target in the opening 45 minutes, although Mark Connolly missed a great opportunity just at the end of the first half.

Moments later, a wonderful flicked header by Greg Kiltie set up Eamonn Brophy to double Killie's advantage.

That's gutting for Dundee United.

Mark Connolly had just missed a glorious chance to equalise with a free header at the back post.

Kilmarnock go down the other end, Greg Kiltie flicks a ball on to Eamonn Brophy and the Scotland striker controls it well while holding off a defender and finishes past goalkeeper Benjamin Siegrist.
