Defending Sprint Cup champion Kyle Busch will make the first of four scheduled Camping World Truck Series starts this season on Saturday afternoon in the Alpha Energy Solutions 250 at Martinsville Speedway. Busch’s last race in the Truck Series was last fall in New Hampshire, where he finished eleventh. His most recent start at Martinsville came in October 2011, when he ran second to Denny Hamlin – who was also driving a Busch-owned entry. In addition to this coming Saturday’s race on the Virginia half-mile, Busch will drive the Number-18 Toyota in Charlotte on May 20th, Kentucky on July 7th and Bristol on August 17th. Although Busch has not personally won a Truck Series race at Martinsville Speedway, Kyle Busch Motorsports has four victories there … two apiece for Hamlin and Darrell Wallace Junior.
