NEWTON, Iowa -- Marco Andretti overtook former Andretti Autosport teammate Tony Kanaan on Lap 232 of 250 and went on to a 0.7932-of-a-second victory in the Iowa Corn Indy 250 presented by Pioneer at Iowa Speedway.
Andretti had passed Kanaan on Lap 209, only to have Kanaan return the favor four laps later. Andretti was running second to Dario Franchitti when they cycled through for their final round of service on Lap 184 under caution. Andretti got out first. On a Lap 199 restart, Kanaan overtook Franchitti for second and the charge to the checkered flag was on.
It was the third victory for Andretti Autosport in the five races at Iowa Speedway, including Kanaan in 2010.
Scott Dixon charged from 23rd on the starting grid to finish third and Target Chip Ganassi Racing teammate Dario Franchitti, who led the most laps, was fifth. Rookie JR Hildebrand, the Indianapolis 500 runner-up, passed Franchitti on Lap 242 for fourth place.
Also on June 25, Josef Newgarden, who overtook pole sitter and Sam Schmidt Motorsports teammate Esteban Guerrieri on Lap 26, turned a 0.3574 of a second advantage into a 5.4724-second victory.
Newgarden, earning his third victory of the season, improved his championship points lead from 13 to 46 over Guerrieri, who retired midway through the race with a mechanical issue (steering) and was credited with 12th place.
Gustavo Yacaman, driving the No. 2 TMR-Tuvacol-Xtreme Coil Drilling car, recorded a Firestone Indy Lights-best runner-up finish. Clauson, competing in his third Firestone Indy Lights oval race, was 5.8 seconds back but also finished a season-high third.
