Williams worked with AM Racing and driver Brett Moffitt throughout the 2023 season, scoring one top-five, nine top-tens and ending the year 15th in the final standings.
Prior to that, he worked with SS GreenLight Racing and won at Auto Club Speedway in 2022 with Cole Custer behind the wheel.
“I am excited about the chance to continue to lead AM Racing in the NASCAR Xfinity Series,” said Williams in a release from the team.
“The team has accomplished a lot in a short amount of time, but there is a lot more to be desired. We continue to work hard to strengthen our Xfinity Series program, and with Hailie behind the wheel, it presents us an opportunity to continue showcasing our efforts but also put her in a position to not only contend for top-10 finishes but hopefully challenge for a win throughout the year too.”
Deegan has spent the last three years competing full-time in the NASCAR Truck Series. Williams was actually the crew chief in her first and currently only Xfinity Series start, which came at Las Vegas Motor Speedway in 2022. She finished 13th on debut.
The 22-year-old is the daughter of Brian Deegan — the most decorated freestyle motocross rider in X-Games history. She will drive the No. 15 Ford Mustang for AM Racing next year.
“I am looking forward to working with Joe (Williams) next year as my crew chief,” said Deegan. “With Joe’s knowledge and experience with AM Racing, alongside the support from the Ford Performance team, I’m really excited to see what we can accomplish together.”
