MADISON, Ill. -- The feud between Carl Edwards and Brad Keselowski -- dormant since Atlanta in March -- erupted like an angry volcano at Gateway International Raceway.

In a drag race to the finish line, Edwards sent Keselowski hard into the outside wall on the way to winning Saturday night's Missouri-Illinois Dodge Dealers 250 Nationwide Series race at the 1.25-mile track. As Edwards took the checkered flag two car lengths ahead of runner-up Reed Sorenson, Keselowski careened into the inside retaining wall and took a vicious shot from Shelby Howard's Chevrolet just short of the finish line.

Less than a lap earlier, Keselowski had bumped Edwards in Turn 1 in an attempt to take the lead after a restart on Lap 199 of 200. Edwards' Ford and Keselowski's Dodge raced side-by-side for most of the final lap. With Keselowski edging ahead as the cars approached the stripe, Edwards turned Keselowski's Dodge, igniting a multicar pileup on the frontstretch.
