On July 16, 2011, Walker won the famed Kings Royal race in the World of Outlaws at Eldora Speedway (owned by Tony Stewart) in Rossburg, Ohio, taking home $50,000 for the win. Walker left the Keen team in August 2011 while competing at the Knoxville Nationals in Knoxville, Iowa. It is reported that he left the Nationals and the team due to an inner ear issue which was causing him to experience vertigo and he felt that he was unsafe to drive a race car.
