Ryan Hunter-Reay ended Penske Racing's domination at Barber Motorsports Park by holding off Scott Dixon to win the IndyCar Series race on Sunday.
Penske drivers Helio Castroneves and Will Power had won IndyCar's three previous races at Barber, but Hunter-Reay beat both for the pole.
The defending IndyCar champion ran a steady race, holding strong in one intense battle for position with both Penske drivers, to claim his first win of the season.
Dixon finished second for the fourth consecutive year on the Alabama road course.
Castroneves was third and Charlie Kimball was a career-best fourth. Power was fifth.
AJ Allmendinger ran seventh for most of his IndyCar debut but finished 20th after stalling his car during his final pit stop.
