What won the race: Fourth-starting Jimmy Mars of Menomonie, Wis., earned $7,000 Sunday at Oshkosh in the sixth annual George Scheffler Memorial for his first Corn Belt Clash victory. Mars took the lead from last year's race winner Chad Simpson on the 25th lap and deftly handled traffic the rest of the way in the 50-lapper. Teammate A.J. Diemel briefly slipped by, but Mars kept him in check while Simpson finished third.
