For 2010, Starr moved to Randy Moss Motorsports as HT Motorsports closed its doors. Starr had 7 top tens and was in the top 10 in points entering the EnjoyIllinois.com 225 at Chicagoland when the team suspended operations due to financial difficulties. Starr picked up a last-minute ride with SS-Green Light Racing in their No. 21 Chevrolet, which was intended to start and park at Chicagoland. However, Starr ran the full race and scored a top-10 finish. Starr eventually took the No. 81 as well as the Zachry sponsorship with him to SS-Green Light and drove for the team the remainder of the season, scoring a 9th-place points finish. Starr returned to the team for the 2011 season, finishing 13th in points. He also competed in a limited number of races in the Sprint Cup Series for Leavine Family Racing in the No. 95. In his 4 starts out of 8 attempts, his best finish of 27th was at Bristol Motor Speedway.
