BROOKLYN, Mich. (AP) Austin Theriault won his ARCA debut Friday at Michigan International Speedway.
The 20-year-old Theriault, from Fort Kent, Maine, is the first driver to win in his first ARCA start since Alex Bowman in 2011. Pole-winner Mason Mitchell led for 65 of the 100 laps but had to settle for second place in the 200-mile race.
Theriault was hired this year to drive three Nationwide Series races for JR Motorsports. He was the 2012 Maine Vintage Race Car Association's Driver of the Year. He made his NASCAR K&N Pro Series debut in 2012 after winning the ''Maine Young Guns.''
Theriault led for 25 laps Friday in his No. 66 Toyota.
