NEWTON, Iowa (AP) — Kenny Wallace has made more starts in NASCAR’s second-tier circuit than anyone. Yet he’s arguably known more for his TV work than his driving. Wallace is set for one last weekend in the spotlight before retiring from NASCAR as a driver. Wallace will make his 547th and final NASCAR Xfinity start Saturday night at Iowa Speedway.

Iowa has become known as a showcase for NASCAR’s youngest drivers. But the attention will be focused on the 51-year-old Wallace, the brother of track designer and Hall of Famer Rusty Wallace.
