St Mirren set the tone early enough by moving in front before the interval, and that 0-1 halftime score shaped the rest of the night. Aberdeen still had time to respond after the restart, but the visitors struck again in the second half to extend the lead and take firm control of the match.
From there, the summary was straightforward: St Mirren stayed in command, protected their advantage and saw out the win without conceding. Aberdeen, by contrast, were left chasing the game and never found the goal that might have shifted the momentum.
The final score also gave the clearest read on the contest. St Mirren were efficient across both halves, while Aberdeen were unable to turn home ground into an edge. Even before the full stats and highlights are added into the wider match package, the result itself stands out - one goal before the break, one after it, and three points earned with authority.
For Aberdeen, it was a frustrating Premiership outing. For St Mirren, it was a disciplined road performance and a convincing 0-2 scoreline to take away.
