Donny Schatz charged from the back of the field Saturday night to win the Knoxville Nationals sprint car race in Iowa for the seventh time in eight years.
Schatz earned $150,000 for winning the world's premier sprint car event. Schatz started 21st, the furthest back of any winner at the nationals. Brian Brown was second, followed by Justin Henderson, Paul McMahan and Chad Kemenah.
The race came less than a week after NASCAR star Tony Stewart, Schatz's team owner, broke his leg racing sprint cars in nearby Oskaloosa.
Fellow NASCAR driver Kyle Larson finished sixth.
