LAS VEGAS -- Martin Truex Jr. won the opening race of NASCAR's playoffs to earn an automatic berth into the second round.
Truex's victory Sunday at Las Vegas Motor Speedway was his series-best fifth of the season and again cemented Joe Gibbs Racing as the team to beat in this 10-race playoff series. JGR has 14 wins this season.
Truex chased down Kevin Harvick, who was slowed by traffic, to cut into Harvick's lead and eventually make the pass for the win on the outside with 20 laps remaining.
Las Vegas was a brutal opener for a handful of title contenders, including Kurt Busch, who crashed when his tire went flat and he finished last in the field.
