In the final practice for the Velocity Prairie Thunder 250 at Auto Clearing Motor Speedway, it’d be L.P. Dumoulin topping the charts behind the wheel of the No. 47 WeatherTech Canada/Dellemare Dodge with a lap of 14.754 seconds.
The defending series champion had a great run last year in Saskatoon, scoring the victory. He has done well thus far this season, finishing in the top-10 in each of the four races thus far.
Scott Steckly, who led the first practice, was second quickest, only 0.014 seconds off of Dumoulin. He enters this event on a string of top-five finishes after finishing fourth at Sunset, fifth at ICAR and winning at EIR on Saturday night. In six starts at ACMS, he has posted two wins and five top-fives with an average finish of 5.5.
Gary Klutt, who won the season opener at Canadian Tire Motorsports Park, was third quickest ahead of Mark Dilley. Dilley is looking for a good run as he has yet to post a top-10 finish thus far this season. Points leader Jason Hathaway rounded out the top-five.
D.J. Kennington was sixth quickest, followed by Matthew Scannell, Joey McColm, Alex Tagliani and James Van Domselaar.
The NASCAR Canadian Tire Series will qualify for Wednesday night’s  Velocity Prairie Thunder 250 at 7:15 p.m. EST with the green flag scheduled for 9:30 p.m.
