Robbie Thomson’s brilliant penalty save triggered the turnaround that saw Cowdenbeath come from behind to claim a crucial win.
Now the young keeper is backing the Blue Brazil to stay ahead in their battle to beat the drop.
The Fifers were already trailing to Scott Taggart’s opener when the Sons were awarded a penalty for a trip on Garry Fleming.
However, Thomson came to the rescue with a great diving stop before Darren Brownlie and Kudus Oyenuga secured an unlikely win to open up a three-point gap over third bottom Alloa.
Thomson said: “Colin Marshall told me he knows where he puts them so I just went for it and I got a strong hand on it.
“I had to because he hit it well.
“When you make a save like that it gives the team a bit of momentum so I’m just happy to help the boys out.”
Both sides squandered chances before Dumbarton went ahead before the break when Scott Linton’s long throw-in created havoc in the visiting defence and Taggart rifled in the loose ball.
Thomson made his vital contribution on 62 minutes when Fleming was upended and Scott Agnew struck the spot-kick to the keeper’s bottom left-hand corner.
But Thomson threw himself full length to claw it round the corner and within 10 minutes his team were ahead.
Colin Nish set up the equaliser with a long cross which was headed on by Lewis Toshney for Brownlie to hammer high into the net.
A carbon copy of Dumbarton’s opener brought the winner when the home side failed to clear Thomas O’Brien’s long throw and Oyenuga was on hand to volley home.
Blue Brazil boss Jimmy Nicholl said: “The penalty save was fantastic it was a crucial, crucial save.”
l Hearts head coach Robbie Neilson admits he will be happy to keep on grinding out wins until the end of the season after a 1-0 triumph over Livingston extended their lead in the Scottish Championship to 20 points.
Neilson said on the club website: “Rangers losing added a bit of pressure.
“The boys were all aware that we had the chance to extend the lead even further.”
