 This is Sports on Radio Iowa. I'm Todd Kim. Joseph Newgarden will try to keep his winning streak alive at the Iowa Speedway this weekend. The back-to-back Indy 500 champion has won six times at the Iowa Speedway, including both ends of an IndyCar twin bill last year. The first of two races this weekend is Saturday night's Hy-Vee Homefront 250. Newgarden says the partial repaving in both sets of turns will make it a different track this weekend, and this afternoon's practice runs will be even more important.
