It was a day to forget for St Mirren as they were on the end of a 5-0 defeat at the hands of Partick Thistle in the Betfred Cup.
It's a result that puts to an end Saints hopes of qualifying for the next round with one match remaining.
An even opening 10 minutes saw both sides go close but it was Jordan Kirkpatrick, making his first St Mirren start, who forced the first save of the match with a long range effort that Tomas Cerny had to do well to push away from goal.
But the home side were ahead two minutes later. There were suspicions of offside as Blair Spittal's knock down found Kris Doolan inside the area and the striker finished low into the far corner beyond Ross Stewart.
The Jags, buoyed by the opener, were on the ascendancy and should have been 2-0 when Abdul Osman found Chris Erskine who held off the challenge of Gary MacKenzie to race clear on goal. The midfielder will have felt he should have done better when his shot was blocked by the legs of Stewart. Credit to the Saints goalkeeper though who did well to deny the 30 year-old.
However, from the resultant short corner Erskine made amends as he received the ball from Steven Lawless on the edge of the box before playing it back to the winger who drilled the Jags into a two goal lead.
The home side were on top but Saints could have got themselves back into the match when Kirkpatrick slipped in Gavin Reilly on the left hand side after capitalising on slack play from Abdul Osman. The striker broke into the box and would have been disappointed not to make the goalkeeper work as he dragged the ball wide.
Soon after it was effectively game over when Lawless notched his second of the match to make it 3-0. Callum Booth picked out Lawless who finished well from the edge of the box.
Saints' misery was further added to a mere four minutes later when Spittal added his name to the list of scorers. Jack Baird was penalised for a foul around 25 yards out and picked up a booking. Spittal stepped up and curled it neatly into the near post leaving Stewart with no chance.
Half Time: Partick Thistle 4-0 St Mirren
Abdul Osman was giving a yellow card for a poor challenge on Stephen McGinn early into the second half that gave St Mirren a free kick in a good area. Lewis Morgan went for goal but sent the effort wide.
10 minutes later Osman was sent packing after another bad tackle on the Saints skipper. Yet almost immediately after the red card Thistle had further extended their lead. The home side won the ball back from the free kick, Erskine skipped by Darren Whyte before sending an excellent ball across the middle to the onrushing Spittal who slid it into the net.
Saints had a couple of opportunities to get themselves a consolation goal with Cammy Smith drilling a shot wide and substitute Ross Stewart heading just over the bar, but it was Ian McShane who really came closest forcing a tremendous save from Cerny. The midfielder looked set to score his first Buddies goal but the Czech goalkeeper pushed away his effort as it was set to find the top corner.
The game, however, was long since over and Saints will close their Betfred Cup campaign at home to Airdrieonians next week before concentrations turn to the Ladbrokes Championship.
