An impressive cup performance saw the Saints fans’ team sink their high flying Rangers opponents and book a cup quarter-final berth.
Three goals inside the opening half hour put the result beyond 10M, who hardly mustered an effort on the Saints goal all match despite being the current league leaders.
Neat strikes from Ryan Keenan, Robert Hillcoat and David Wilson means the St Mirren supporters’ side can look forward to a last eight clash with Partick Thistle.
Buoyed by the senior team’s victory the day before, the Saints side headed for Easterhouse confident they could go one better than the last time they faced 10M, the match ending 3-3.
With coach Mark Syme caught up with work, Gordian Mothersole assumed control – and named an attack-minded line up, with Keenan making a welcome return to the starting line-up.
Defender Chris Adam bolstered the defence, returning after injury, while Duncan Johnston was pushed into central midfield.
10M enjoyed the early possession, but were soon feeling flustered as Saints pressed them high up the park.
And the home side were quickly caught on the break as David Christie won the ball in midfield before Hillcoat sent Keenan through on goal. With time to think, the speedy striker coolly slotted passed the Gers keeper.
Just five minutes later and Keenan was at the heart of goal number two for the Mirrenoff. He heaped further pressure on the stretched 10M defence, forcing the keeper to rashly swipe at a clearance, which ricocheted off Keenan and into Hillcoat’s path. Ten yards out and with the goal gaping, the eagle-eyed frontman graciously accepted the tap in.
A two goal cushion soon became three as the 10M keeper conspired to sell the jerseys once more. His hashed clearance from the edge of the box reached Wilson on the half way line.
The quick thinking midfielder showed little hesitation, returning the ball first time fully 45 yards straight into the empty net.
It was little more than Saints deserved for their high tempo approach, and Gers slumped off seeking solace in the half-time oranges.
But having previously let a two-goal slip when the two sides last met, Saints were in no mood for such profligacy on this occasion.
And with Ian Craig, Muir and Fraser Gray clearing their lines a la Will Haining at Fir Park, the 10M strikers hardly had a sniff.
In fact, great wing play from Andy Tucker almost led to further goals for the travelling buddies, who passed up a number of chances to put the result beyond doubt.
Finally, with 20 minutes to go, Saints keeper Craig Muir was called into action, acrobatically tipping over a drive from distance.
Saints aged bench, namely Mothersole and Barry Johnston, entered the fray in the final stages and the experienced duo helped to close out a great team performance.
Next up for the Buddies is a league clash with Ayr United on Sunday, kick-off 2pm at the Elderslie Amateurs FC pitch.
