The Owen Sound Attack won their 15th game in a row but the Barrie Colts didn't make it easy.
David Ovsjannikov stopped 37 shots by the Attack before Petrus Palmu beat him in overtime to secure a 3-2 win for Owen Sound.
Emanuel Vella made 16 saves for the Attack.
Palmu's game winner came at 1:51 into overtime.
Jason Smith put the Colts on the board just under seven minutes into the game. They held a one goal lead for just over ten minutes until Aidan Dudas tied the game at 1-1 going into the seconds.
Cordell James put the Attack ahead by a point just under four minutes into the second. Zachary Magwood tied the game again just over three minutes later. Neither team would score in the third.
The Attack are now just four points back of London and Erie in the Midwest Division. The Knights and Otters both have 67 points with Erie in second place with three more losses.
The Attack have a chance to narrow the gap further tomorrow afternoon when they host the Knights at the Harry Lumley Bayshore Arena.
