Second-half goals from Mikael Mandron and Toyosi Olusanya helped 10-man St Mirren to a 2-0 home win over Dundee in the cinch Premiership.

James Bolton was sent off for the home side late on after Mandron had put them in front but the visitors could not capitalise on the man advantage and conceded a second goal to Olusanya late on.

The victory extended fifth-placed Saints’ advantage over Dundee to nine points albeit having played two games more.

Manager Stephen Robinson went with the same starting line-up that thrashed Hibernian 3-0 at the weekend, with returning Australia international Keanu Baccus named among their substitutes.

Dundee, in turn, made just one change from their defeat to Hearts, with former Saints striker Curtis Main replacing Amadou Bakayoko in attack.

Kick-off was delayed by 30 minutes after the Dundee team bus was caught in traffic on their way to the stadium from their hotel.

It was the home side who had the first real chance, with Mandron’s turn and shot well off target.

Elvis Bwomono then unleashed a long-range effort that similarly flew over the crossbar.

Dundee responded with a Jordan McGhee header that was also off target before Trevor Carson was the first goalkeeper called into action to save Mandron’s low effort at the other end.

Alex Gogic then came close to opening the scoring with a flicked header from Greg Kiltie’s corner but it drifted just wide of the far post.

James Scott launched a shot that nearly sailed over the stand as St Mirren turned up the pressure without giving the Dundee defence too much to worry about.

The visitors almost forged in front on a counter-attack following a St Mirren corner.

Luke McCowan sent Owen Beck running clear from just outside the Dundee box but he was tracked all the way by Hyeok-kyu Kwon, on loan from Celtic, who did well to block the Liverpool loanee’s shot. Beck then pulled his second effort wide.

Saints had the first chance of the second half but Bolton’s header from Caolan Boyd-Munce’s corner lacked the power to beat Carson.

Gogic then headed wide from Kiltie’s free-kick before Baccus’ drive from the edge of the penalty box touched the top of the crossbar before going over.

St Mirren’s pressure finally told after 73 minutes when they went ahead. Mandron’s strike looked to be covered by Carson but the Northern Irishman could only push his shot into the net.

Mandron then passed up a gilt-edged chance to double the home side’s lead before substitute Lewis Jamieson saw his low driven shot well saved by Carson and Kiltie blazed an effort wide at the far post.

St Mirren played out the last five minutes with 10 men after Bolton was sent off for a heavy tackle on Owen Dodgson before Olusanya sprang the Dundee offside trap to score their second goal in stoppage time.
