In a war of attrition that caused a multitude of problems for the majority of Monster Energy NASCAR Cup Series Playoff contenders, Brad Keselowski emerged unscathed with his third straight victory in the series and the 500th triumph for Team Penske in all forms of racing combined.

Sunday’s South Point 400 at Las Vegas Motor Speedway, the playoff opener for NASCAR’s foremost series, went to overtime, lasting five laps longer than the scheduled 267. But Keselowski held the top spot through three tension-laden restarts to beat runner-up Kyle Larson to the finish line by 1.276 seconds on the final two-lap shootout.
