Brad Keselowski overcame an early pit-road speeding penalty Saturday to win the rain-delayed NASCAR Xfinity Series at ISM Raceway.
Keselowski took the lead from Christopher Bell off a pit stop with 32 laps left and pulled away in the race that was delayed two hours because of light rain at the mile oval southwest of Phoenix.
Keselowski was caught speeding during the caution period following a rain delay of 1 hour, 35 minutes. The 200-lap race was delayed again for 25 minutes just before the end of the first 45-lap segment.
Keselowski has 37 Xfinity victories, also winning the 2014 fall race in Phoenix. The Cup driver has won his last two Xfinity starts, taking the Richmond event last year.
Justin Allgaier, the pole-winner and defending race champion, finished second — 0.530 seconds back. He won the first 45-lap stage.
Kyle Busch was third. He took the second stage, holding the lead on a one-lap shootout after the second delay.
Bell was fourth, and Jamie McMurray took fifth in his first series start since 2013.
