Overview
- Larson won the Enjoy Illinois 300 in double overtime after a race that set a season and track record with 18 cautions and two late red flags.
- The win snapped Larson’s 51-race winless streak and vaulted him from seventh to second in the 10-race Chase standings, closing to nine points behind leader Denny Hamlin.
- Mechanical failures, notably catastrophic brake and rotor problems, and a series of late multi-car wrecks produced nine DNFs overall and knocked five Chase drivers out of contention.
- Hendrick Motorsports supplied the top results with Larson first, Alex Bowman second and William Byron fourth, and Larson’s four-tire stop late in the race beat Joey Logano’s two-tire call.
- NASCAR will review the brake failures as teams prepare for the Bristol Night Race on Sept. 19 with the Chase tightened and strategy and reliability now central concerns.
