TALLADEGA, Ala. (AP) — When an engine failure knocked title favorite Martin Truex Jr. from NASCAR’s playoffs, the rest of the top contenders got a little bit of breathing room. Then Brad Keselowski suffered the same cruel elimination when his engine failed Sunday at Talladega Superspeedway. There was suddenly a wide-open competition to earn the final transfer spots into the third round of the Chase, and Denny Hamlin and Austin Dillon raced a tense final two laps in overtime to fill the bracket.
