What won the race: Leading all 40 laps, Late Model rookie Tyler Peterson of Hickson, N.D., held off veteran John Kaanta to pick up his second consecutive Structural Buildings WISSOTA Challenge Series victory in Sunday's 11th annual Marilyn Olson Memorial at Casino Speedway, earning $3,000.

Quotable: “Oh man, I didn’t feel like I had a dominating race car,” Peterson said. “It was completely different than it was last night, we just left the car alone and it seemed to work out for us. I knew with John (Kaanta) and especially Chad (Becker), he races here all the time, he’s really fast here right behind me and there were like 90 yellows, I was like they are trying to give this win to Chad. (I had an) awesome car, want to give a big shoutout to my boss Adam for giving me a hell of a race car to work with here.”
