Overview
- Chase Elliott executed a decisive last-lap pass on Brad Keselowski to claim his 20th career victory and secure his place in the next round of NASCAR’s inaugural In-Season Challenge.
- A 23-car pileup early in Stage 2 brought out a red flag and eliminated top seeds including Denny Hamlin, Joey Logano and William Byron from tournament contention.
- Lightning-delayed qualifying saw Joey Logano on pole before rain and storms forced multiple cautions and stoppages during the 260-lap Quaker State 400.
- EchoPark Speedway’s shorter superspeedway layout intensified pack racing risks and strategic pit calls as changing conditions disrupted the field.
- With the field cut in half, the Cup Series now shifts to the Chicago Street Race for the Challenge’s Sweet 16 round.
