One of NASCAR’s most famed crew chiefs of the last few decades is returning to the top of the pit box.
Jeff Hammond will be the crew chief for Clay Greenfield in the NASCAR Gander RV & Outdoors Truck Series in 2020, the team announced Tuesday, Jan. 28.
Hammond will lead the part-time team’s efforts in what’s currently planned to be an eight-race schedule, beginning next month at Daytona International Speedway.
“It’s like coming full circle to be able to return to the top of the box for such a first-class team and a hungry driver like Clay Greenfield,” Hammond said in a team release. “I believe this Rackley Roofing No. 68 is going to turn some heads and prove that we’re a team to respect!”
Added Greenfield, “We are thrilled to have a legendary crew chief like Jeff join our team and help take us to the next level. With the addition of Jeff combined with equipment upgrades Rackley Roofing has allowed us to make, we are poised to have the most successful season in CGM’s history.”
After coming to prominence as the championship-winning crew chief for Darrell Waltrip beginning in the ’80s, Hammond transitioned to a television analyst role beginning in the 2000s, last crew chiefing in the NASCAR Cup Series for Chad Little in 2000.
Greenfield will again be sponsored by Rackley Roofing during his Truck Series campaign, which could expand past eight races.
In 46 Truck starts, he has two top 10s while generally entering anywhere between two and six races each season the last few years for his self-owned team, particularly at Daytona and Talladega Superspeedway.
