NEWTON, Iowa – Austin Dillon knows that Saturday night's NASCAR Nationwide race in Iowa might be his best shot yet at a victory.
But it's not necessarily because Dillon is running so well. It's mostly because Kyle Busch is staying at Pocono Raceway.
Dillon, who took over the Nationwide points lead last week despite going winless through 19 starts, headlines a field almost exclusively made up of Nationwide regulars.
Brad Keselowski is the lone Sprint Cup driver scheduled to be in the field.
NASCAR's top series runs Sunday in Pennsylvania. Busch, who has won eight Nationwide races in 15 tries in 2013, won't attempt the Pocono-Iowa double-dip like he's done in the past.
