Changes made to pit crews of Christopher Bell, Bubba Wallace

The teams of Christopher Bell, who holds the final playoff spot, and Bubba Wallace have made pit crew changes for Sunday’s Cup race at Atlanta Motor Speedway.

Bell’s team will have two new tire changers and a new tire carrier.

Bell’s team also has AJ Rosini as the new rear tire changer. Rosini served as a tire changer with Chip Ganassi Racing’s IndyCar team of reigning series champion Alex Palou in select races, including the Indianapolis 500.

Rosini served as a tire changer for Wallace’s team at Richmond, Martinsville and Talladega when the team’s rear tire changer received a NASCAR suspension for a wheel coming off the car. Rosini also served as a tire changer on Kyle Busch‘s team last month at World Wide Technology Raceway and Sonoma as an injury replacement.

Wallace’s team will have Houston Stamper as the new front tire changer and Joe Crossen as the new tire carrier. Both came from Bell’s team. Crossen had been with Bell’s team all season. Stamper had been on Bell’s team since Kansas in May.

The change to Bell’s team marks the sixth different pit crew unit it has had this season. Bell enters Sunday’s race at Atlanta (3 p.m. ET on USA Network) with a 20-point lead on Kevin Harvick for the final playoff spot. Eight races remain in the regular season.
