Michael Kantor scored both goals for the Wolves (26-23-11), who have dropped back-to-back contests.
Guelph's Garret Sparks made 24 saves for the win as Sudbury's Taylor Dupuis took the loss after allowing six goals on 21 shots. Franky Palazzese replaced Dupuis in the second period and stopped 14-of-15 shots in 24 minutes of relief.
The Storm went 1 for 2 on the power play while the Wolves failed to score on three chances with the man advantage.
I remember the first time at Wrigley Field all of us had the long johns, the turtlenecks and the extra equipment because we were afraid of being cold. Halfway through the first period everybody's ripping everything off and we just ended up wearing what we would normally wear for a game at the United Center.
