Cole Custer won his first NASCAR Camping World Truck Series race Saturday night, taking the weather-delayed 200-mile event at Gateway Motorsports Park.
Custer, 17, took the lead on a restart on the 155th lap of the 160-lap event.
Spencer Gallagher was second. Veteran Johnny Sauter finished third.
Custer, a native of Ladera Ranch, Calif., passed Tyler Reddick to take the lead for good at the 1.25-mile oval. He started from the outside of the front row with a practice speed of 136.591 mph; the qualifying event was rained out earlier in the day.
The start of the race was delayed 1 hour, 57 minutes by rain.
Matt Crafton, the series leader, finished 21st, but remained 12 points ahead of Reddick, who finished eighth, in the series standings after the eighth of 22 races.
Erik Jones led more than half the race before a late accident doomed him to a 23rd-place finish. Brandon Jones, who skipped his high school graduation ceremonies at Lake Norman High in Lake Norman, North Carolina to compete, finished 12th.
