Clay Greenfield Bio
Clayton Michael Greenfield, known professionally as Clay Greenfield, is an American professional stock car racing driver and team owner. Born on June 3, 1984, in Clarksville, Tennessee, he has competed across several NASCAR national series and regional touring divisions, building a reputation as a persistent part-time competitor. He last drove part-time in the NASCAR Craftsman Truck Series, piloting the No. 95 Chevrolet Silverado RST for GK Racing.
Early Life and Background
Clayton Michael Greenfield was born and raised in Clarksville, Tennessee, a city in the middle part of the state with a strong military and motorsports presence. He attended Clarksville Academy, the same private school that has produced several athletes from the region. Growing up in the South, Greenfield was exposed to short tracks and grassroots racing events that have long served as a starting point for many stock car drivers.
His early interest in racing led him toward stock car competition, the most popular form of auto racing in Tennessee and the surrounding states. Like many young drivers, he began his career in local and regional series, working his way up the ladder while balancing the demands of school and racing. These formative years gave him the experience needed to eventually move into NASCAR-sanctioned events.
Path to NASCAR
Before reaching NASCAR, Greenfield built his foundation in the UARA-Stars Series, a regional late model touring series based in the southeastern United States. The series served as a proving ground for aspiring drivers, and his time there helped him develop the race craft and consistency required to attempt bigger events.
In the mid-2000s, Greenfield expanded into the ARCA Racing Series, where he made several qualifying attempts. His ARCA debut came at Salem Speedway in 2004, driving for Wayne Peterson Racing, and he finished twelfth, which was the team’s best race result since 1998. These early ARCA outings gave him valuable experience on intermediate and short tracks, setting the stage for his eventual jump into NASCAR national series competition in 2010.
Clay Greenfield Career
Early Career (2010-2012)
Clay Greenfield made his NASCAR debut in 2010, driving for Team Gill Racing in the Camping World Truck Series at Martinsville Speedway. Over the following three seasons, he competed in 22 Truck Series races, gradually learning the demands of NASCAR’s national tour. His best result during this period came at Daytona International Speedway in 2012, where he finished tenth, a strong showing on one of the sport’s most challenging tracks.
In 2011, Greenfield also made his debut in the NASCAR Nationwide Series, finishing 35th at Atlanta Motor Speedway behind the wheel of the No. 71 for Rick Ware Racing. The start gave him a brief taste of the second-tier national series, even though his time there was limited.
NASCAR Craftsman Truck Series Breakthrough (2013-2020)
Greenfield began the 2013 Truck Series season in impressive fashion, posting the fastest time in practice for the season-opening event at Daytona International Speedway. Although he finished 26th in the race, the performance showed that he could compete with established teams. Later that season, he ran additional events with Norm Benning Racing, including a memorable qualifying battle at the Mudsummer Classic.
After several years away from the Truck Series, Greenfield returned in 2020 for a part-time schedule. That year also marked a significant change for his program, as he convinced Fox NASCAR commentator and two-time Cup Series champion crew chief Jeff Hammond to come out of retirement. Hammond served as crew chief for Greenfield’s No. 68 entry for the races in which it was entered. The partnership added credibility and experience to his part-time effort.
GK Racing Era (2021-Present)
In 2021, Greenfield was due to run the full Truck Series season but faced sponsorship limitations, allowing him to compete in only a handful of races. He failed to qualify at Daytona, Nashville, and Gateway, but he did qualify for Darlington, where he scored an impressive nineteenth place finish. Later in the year, he joined Spencer Davis Motorsports for the UNOH 200 at Bristol Motor Speedway, continuing his run of team-hopping to stay on track.
More recently, Greenfield has been associated with GK Racing, where he has driven the No. 95 Chevrolet Silverado RST. As a driver and team owner, he has continued to enter races on a part-time basis, balancing the business side of racing with the demands of competition. His current role reflects a long-term commitment to staying involved in the Truck Series on his own terms.
Driving Style and Strengths
Greenfield’s track record shows a driver who performs well on superspeedways and flat tracks, with his best Truck Series finish coming at Daytona. His experience across regional series, ARCA, and the Truck Series has made him a versatile competitor. The partnership with veteran crew chief Jeff Hammond in 2020 highlighted his ability to lean on experienced personnel to improve his results.
Notable Races and Milestones
Among the highlights of Greenfield’s career are his 2012 tenth place finish at Daytona, his fastest-practice run before the 2013 Daytona opener, and his 2020 return to the Truck Series with Jeff Hammond calling the shots. His 2021 nineteenth place run at Darlington also stands out as a strong performance given his part-time status.
Clay Greenfield Career Wins
Clay Greenfield has competed across multiple stock car racing series throughout his career, including the UARA-Stars Series, ARCA Racing Series, NASCAR Nationwide Series, and NASCAR Craftsman Truck Series. While he has not secured victories at the national NASCAR level, he has posted several respectable finishes, including a top-ten result in the Truck Series at Daytona in 2012.
NASCAR Craftsman Truck Series Highlights

He has continued to enter races on a part-time basis, working with multiple teams including Team Gill Racing, Norm Benning Racing, Spencer Davis Motorsports, and GK Racing.
Other Wins and Performances
Outside of the national NASCAR series, Greenfield competed in the UARA-Stars Series and the ARCA Racing Series, where his twelfth place debut at Salem Speedway in 2004 marked the best result for Wayne Peterson Racing since 1998. While specific regional wins are not clearly documented in available records, his consistent presence in the Truck Series demonstrates his dedication to the sport.
Clay Greenfield Family
Family Background and Racing Lineage
Public information about Clay Greenfield’s immediate family and any racing lineage is limited. He attended Clarksville Academy in Tennessee, suggesting roots in the local community, but specific details about parents or relatives involved in racing have not been widely documented.
Personal Life
Greenfield resides in the Clarksville, Tennessee area and continues to balance his roles as a driver and team owner in the NASCAR Craftsman Truck Series. Further details about his personal life, including marital status and children, are not publicly confirmed in available sources.
2025 Season Performance
Clay Greenfield’s 2025 plans have not been formally announced in widely available sources. As a part-time competitor and team owner with GK Racing, he has historically entered selected Truck Series events when sponsorship and equipment allow, and 2025 is expected to follow a similar pattern. His focus remains on the No. 95 Chevrolet Silverado RST program.
Given his history of late-season entries and team partnerships, any 2025 schedule is likely to include superspeedway and short track events where he has historically performed well. His past results at Daytona and Darlington suggest these types of tracks could remain priorities if he returns to competition this year.
As the season develops, Greenfield’s outlook will depend heavily on sponsorship agreements and the readiness of his GK Racing team. His experience and persistence have kept him active in the Truck Series for more than a decade, and he is expected to continue pursuing select races when opportunities arise.
