Cambridge, Wisconsin native Matt Kenseth won the Geico 400, finishing just ahead of Joe Gibbs Racing teammate Kyle Busch at Chicagoland Speedway.
Kenseth entered as the top seed in the Chase for the Championship and showed why after two rain delays that totaled 6 1/2 hours. He passed Busch on a restart with 23 laps remaining and padded his lead in the Sprint Cup points race.
Kenseth is in his first season with Joe Gibbs Racing. He won five times in the first 26 races, which is a series best.
The last two Sprint Cup winners started their run by winning at Chicagoland. Tony Stewart did it in 2011 and Brad Keselowski pulled it off last year.
