What won the race: Topping Cole Searing for the second straight night at Fiesta City Speedway, Tyler Peterson of Hickson, N.D., led the final six laps for a $3,000 victory and Structural Buildings WISSOTA Challenge Series sweep. Peterson, notching his sixth career series victory, matched Searing with his third triumph of the season.

Quotable: "That's our motto, man, never give up. It's always lapped traffic that makes the race good. I've been (touting) since the beginning of the year. It makes or breaks a race for you," Peterson said. "I was concerned about my tire. Man, I didn't know how hard we'd go in that rubber over there, but we just kept it to the floor and made the right moves in lapped traffic."

Key notes: Peterson notched his 184th career multidivision feature victory. ... In Friday's weekend opener, Peterson used a last-lap pass after series points leader Cole Searing slowed with a flat left-rear tire. … A dozen drivers completed 40 laps. ... Twenty cars were running at the finish. ... Josh Zimpel scratched from the scheduled 26-car feature.

On the move: Cory Crapser of Chippewa Falls, Wis., started 19th and finished seventh.
