Partick Thistle came from behind to beat Airdrieonians in the Scottish Championship, thanks to second-half goals from Daniel O'Reilly and Alex Samuel.
Cole McKinnon put Airdrieonians in front against his former side after just three minutes with a powerful shot from outside the box and Danny Lennon's side deservedly led at half-time as Thistle struggled to find an attacking spark.
That theme continued after the break but, as Airdrieonians tired, Thistle found their stride in fine style. O'Reilly got on the end of an Aidan Fitzpatrick corner to head home the equaliser on 77 minutes, before substitute Samuel reacted quickest to put the hosts in front just five minutes later.
Both sides had opportunities in the closing stages, but Thistle stood firm to take all three points.
Lennon has lost both matches since taking over as Airdrieonians manager and they are still searching for a first Championship win this season.
Thistle have 10 points from their five league matches and are level with leaders St Johnstone, Raith Rovers and Arbroath before the weekend's fixtures.
