St Mirren kept their European hopes alive as Mikael Mandron's composed finish earned a hard-fought 1-0 win over Aberdeen at the SMISA Stadium.
The striker, who signed a new contract this week, controlled Mark O'Hara cross on his chest and rifled home the game's only goal after an hour.
Aberdeen started well and Jeppe Okkels had a goal ruled out by VAR, but they faded in the second half as they fell to a first defeat in nine games.

St Mirren could have extended their lead deep into stoppage time as substitute James Scott saw his goalbound shot blocked, but a single goal was enough for Robinson's side.
The win moved them to within five points of fifth-placed Dundee United in the last remaining European spot.
