Indy Pro Series title hopeful Bobby Wilson has been docked five points for improper advancement of his position during the Valley of the Moon 100 at Infineon Raceway.

During the race, Wilson avoided a chicane in the course and drove through a tyre barrier runoff area. In the process, Wilson, who was in second place, passed a lapped car and increased his lead over the third-place car.

Wilson remains in third place in the overall driver point standings, 24 points behind leader Jay Howard. He is one of four drivers eligible to win the championship in the season finale at Chicagoland Speedway next weekend.
