Overview
- After the Sonoma race, Denny Hamlin leads the 2026 NASCAR Cup standings by a single point over Tyler Reddick, marking the first time Reddick has lost the season-long lead.
- Tyler Reddick suffered an intermittent power-steering failure that left him several laps down and ultimately in last place, though he picked up the fastest-lap bonus.
- Denny Hamlin was spun late in the race, damaged his splitter, and finished 26th but still collected enough points to erase an eight-point deficit and move into the lead.
- Race replays showed Brad Keselowski making contact with Carson Hocevar, which forced Hocevar into Hamlin and caused the spin, and Hamlin declined to assign blame publicly until he reviewed the footage.
- Shane van Gisbergen won at Sonoma and vaulted back into the Chase, while Erik Jones fell to 17th and out of the playoff cutline and Austin Cindric now sits narrowly on the bubble ahead of the run to Chicagoland.
