Jeff Olschowka's reign in the street stock division at Marysville Raceway Park came to an end Saturday night, after he spun on the 18th lap while running third.

Olschowka, of Yuba City, had won the previous four street stock main events on the quarter-mile clay oval, but Robert Mull of Marysville took the checkered flag with a pass of race leader Craig Eubanks of Yuba City coming out of turn four on the last lap.

Tony Richards of Paradise, who started on the pole in the wingless sprint car main event, won, leading all 20 laps in a race that was slowed a couple of times by yellow flags. Several cars slammed into each other after the finish line right at the start of turn one, while a couple of cars flipped.

Ryan McDaniel of Marysville won the modified feature race.

Fourteen-year-old Trevor Canales of Roseville won the micro sprint 600 main event, holding off Kenny Allen of Chico.

Josh Hiatt of Stockton won the NorCal dwarf cars main event, passing Dan Weger of Grass Valley on the inside of turn two on the last lap.

Bill Knoop of Hallwood, the series points leader in the street stocks, spun in turn two on lap five of the main event. He was in third place at the time, but the spin shuffled him to the back of the field and eventually to the pits and out of the race.

Olschowka ran a good part of the 20-lap race in third or fourth place but with two laps to go, he spun in turn two, dropping him to the rear of the field.

Eubanks, who led the street stock feature since the third lap, was looking to take the checkered flag coming out of turn four when Mull slipped inside and sent Eubanks into the wall at the start of the front stretch.

Mull wobbled to the finish line for the win, followed by Corey Hall of Sutter.

Unofficially, Olschowka finished fourth while Knoop was ninth. Knoop led Olschowka by 20 points coming into the night's program and should still maintain his lead in the points standings when the results are made official on Tuesday.

Randy McDaniel of Marysville, who won the first of six modified races at Marysville, was running second for several laps until be passed Mitch Murphy of Susanville on lap nine. McDaniel's place at the top was short-lived as on the next lap he dropped off the pace, fading to the back of the pack and eventually the pits.

Ryan McDaniel passed Shawn Natenstadt of Fernley, Nev., with two laps to go and held on for the win.

Mason Myers of Browns Valley won the wingless sprint car B main event. Twenty-eight cars started the night in the wingless sprint class.

Heat race winners were Olschowka and Knoop in the street stocks, Brett Youngman of Grass Valley, Cody Myers of Lincoln, Taylor Simas of Orland and Terry Shank Jr. of Santa Rosa in the wingless sprints, Ryan McDaniel and Natenstadt in the modifieds, Matt Peterson of Wilton in the micro sprint 600s, and Kevin Bender of Rocklin, Brett Barstow of Ballico and Weger in the NorCal dwarfs.
