A LACKLUSTRE St Mirren fell to their first home defeat since January, losing 1-0 to Dumbarton at the Paisley 2021 Stadium on Saturday.

Saints never got going, and matters were made worse for the hosts when Stelios was sent off for leading with his elbow when challenging for a header minutes before the break.

Tom Walsh, one of the five ex-Saints players in their starting line-up punished the Buddies on 80 minutes, meaning Saints slipped to second place in the Scottish Championship with Dundee United winning.

Jack Ross made one change to their weekend win at Livingston, Cammy Smith picked up a groin injury on Friday, with Stelios replacing him.

Dumbarton were attacking from the off, and signalled their intent from the start with a long range effort being tipped wide by Craig Samson two minutes in.

The visitors were dealt a blow six minutes in, when Mark Stewart was replaced after picking up a hamstring injury.

Saints first shot came from Kyle Magennis, the youngster dribbling past several Sons players before firing wide from outside the box.

In a quiet first half with few chances, the defining moment came two minutes before the break.

Stelios led with his elbow on an aerial challenge with Sam Wardrop, leaving Andrew Dallas with little choice but to send off the Cypriot.

And unlike in their midweek victory over Livingston, there was no second half comeback from St Mirren.

The Buddies improved slightly in the second period, but playing with a man less meant they had to take more risks at the back.

Walsh and Stuart Carswell had chances early on in the second period, before Lewis Morgan whistled over an effort from just outside the box on 63 minutes.

The away side had their best chance so far when Ally Roy was played in by Calum Gallagher, but the Hearts loanee fired wide when in one-on-one with Samson on 73 minutes.

Dumbarton’s goal was what they deserved after edging Saints for much of the 90 minutes.

Froxylias playing in Walsh, who drifted past Adam Eckersley before cutting inside and firing into the net on 80 minutes.

The only nervous moment for the Sons came in injury time, when goalkeeper Scott Gallacher, who had little to do all day, spilled a cross, but it was eventually scrambled to safety.

St Mirren will be looking to bounce back away to Brechin City on Saturday, kick-off at Glebe Park is at 3pm.
