Mason Diaz is an American stock car racing driver whose career included stints in the NASCAR Xfinity Series, the NASCAR Camping World Truck Series, and the CARS Tour before he moved into ARCA competition with Ferrier-McClure Racing, where he most recently ran the No. 44 Toyota part-time in both the ARCA Menards Series and the ARCA Menards Series East. Diaz came up through short-track and regional stock car racing before advancing into NASCAR's national touring divisions, using the Xfinity Series as his primary platform at the national level.[1]
In the NASCAR Xfinity Series, Diaz made six career starts without recording a win or a podium finish, a body of work reflecting a limited, developmental level of participation rather than a full-time campaign. His Racer Rating of 2,560 places him 1,452th among active drivers on a scale where the sport's elite competitors reach figures in the range of 10,000 to 11,500, underscoring the early and largely undeveloped stage his top-level career reached. In the 2026 season he competed in two rounds without a win or podium, finishing 83rd in the standings, and his status is now listed as retired, closing out a career of six Xfinity Series starts and zero championships across his time in the sport.[2]
