Saints had to settle for a point after Hibernian battled back from 2-0 down to draw 2-2 at Easter Road.
Two goals in four minutes from Conor McCarthy and Tony Andreu had St Mirren deservedly ahead inside the first 20 minutes.
But Hibernian hit back before half-time thanks to goals from Scott Allan and in-form Christian Doidge.
The Buddies started strongly in the capital and earned their reward on 14 minutes when McCarthy scored his first St Mirren goal to put Saints ahead. The Irish defender was presented with a free header inside the Hibees box to bullet home from a Cammy MacPherson corner kick.
Saints were worthy of their lead but the home side looked to respond quickly with Martin Boyle forcing Vaclav Hladky into a decent stop at his near post on 17 minutes.
But just a minute later Saints doubled their lead. McCarthy send a terrific cross-field pass to Ilkay Durmus who brought the ball down well and raced away from David Gray to make his way into the Hibernian box. The winger laid the ball back to Tony Andreu with the Frenchman sliding home to make it 2-0.
Hibernian pulled a goal back on 25 minutes through Scott Allan. The midfielder drove forward into the Saints half before switching wide to Boyle on the right side. Allan continued his run into the box to meet Boyle low ball across to stroke home.
The Buddies were still looking strong with Durmus firing over from range on the half-hour mark, while Hibs goalkeeper Ofir Marciano had to be alert to push away a MacPherson free-kick and a low ball in from Morias. Andreu shot over after the latter's opportunity fell to him on the edge of the area.
Frustratingly, Hibernian found a leveller just two minutes before the interval. Saints couldn't clear their lines allowing Stephane Omeonga to flight the ball into Doidge who headed beyond Hladky from close range.
St Mirren could have gotten the second-half off to the perfect start when, just six minutes in, Marciano spilled a Durmus cross into the feet of Andreu but the Frenchman couldn't get the shot away with the Hibernian goalkeeper managing to gather.
Jim Goodwin made a double substitution on 64 minutes when Jamie McGrath & Alex Jakubiak came on in place of Andreu & Morias. It came just seconds after Morias had nodded agonisingly wide from a MacPherson free-kick.
Hibernian substitution Paul McGinn, who yesterday completed his move from Saints to the Hibees, almost came back to haunt the Buddies on 70 minutes when he rose the highest to head a free-kick goal-ward with Hladky doing well to push wide.
Hibernian were almost gifted a goal with 15 minutes remaining when Sam Foley's attempted header to Hladky was pounced upon first by Boyle, but the Saints defence did well to get back and deflect the forward's effort wide.
Three minutes later Allan almost grabbed his second directly from a corner. The midfielder's ball in from the left looped over Hladky but crashed off the Saints bar.
That was the closest either side would come in the final stages of the match with Saints taking a point back to Paisley.
