Marsh ran in the second spot until he spun in Turn 4 on Lap 33, bringing out the fourth of five caution flags.
Marsh was credited with a seventh-place finish.
Jason Atkinson appeared headed for a top-five finish, swapping the fourth spot with Crabtree several times over the final 15 laps when he broke a suspension part and pulled into the infield pit area.
Cordy Horn recorded his first career win at Anderson Speedway in the Mel Kenyon Midget Series feature, leading the entire distance.
Horn started on the pole position thanks to the four-car inversion, with Grant Galloway chasing him for most of the race. Galloway was passed by fast-qualifier Spence Bayston coming off the fourth corner on the final lap to claim the second spot.
Galloway finished third, followed by Cole Fehr and Jessica Bean.
