Shelbourne extended their unbeaten SSE Airtricity Men's Premier Division run to five games with a 2-0 win over Sligo Rovers at the Showgrounds, bouncing back from a disappointing European performance mid-week.
Ali Coote and Sean Boyd were the goalscorers as Joey O'Brien's side moved to within three points of Drogheda United in fourth.
A bad night for Sligo was made worse with six minutes to go when goalkeeper Sam Sargeant was sent off as he was judged to have handled the ball outside the box by referee Rob Harvey, although replays suggest it may have been on the line.
Unbeaten in their last five league games, the Bit O'Red were one of the league's form sides coming into this tie.
A win against the 2024 Premier Division champions would have brought Russell's men level on points with Galway United who were beaten on Friday by the league's bottom side Cork City.
Russell lost both Jake Doyle-Hayes and Francely Lomboto this week, with both players departing the club, while Ciaron Harkin joined from Derry City and was named on the bench for this game.
Shels, who had a gruelling trip home from Kazakhstan mid-week where they were in European action, named Milan Mbeng after the French man signed from Cork City.
Cian Kavanagh's miss on ten minutes was the talking point in an otherwise uneventful first-half, with neither side bringing the entertainment that may have been expected.
The former St Patrick's Athletic striker just needed a slight touch to divert the ball past Speel in the Shels goals after Will Fitzgerald's free-kick was knocked on in the direction of Kavanagh in front of goal.
That was as close as either side would come to opening the scoring in the first-half, but Shels found the net two minutes into the second-half.
Coote got a hold of possession in the middle, and pushed his way past a couple of Sligo players before driving into the top corner with Sam Sargeant well beaten in the Sligo goals.
Paddy McClean almost had Sligo back on level terms but the Derry man couldn't keep his header down from Owen Elding's cross as Sligo battled hard to find an equaliser.
John Russell responded to his side's inability to break Shels down by switching up their approach, in truth it was game over on 77 minutes when Boyd added a second for Shels.
As the home side failed to clear the ball from their defence, John Martin picked out the free Boyd in front of goal, and all he needed to do was poke it in past Sargeant for 2-0.
There was further controversy, though, as the home side were reduced to ten when referee Rob Harvey gave Sargeant a straight red card for handling the ball outside the box, but replays show that Sargeant looked to be on the line as he handled the ball.
That result leaves Sligo in ninth place, three points off Galway in eighth, while Shels are just three points off Drogheda United who occupy fourth spot.
