Ryan Blaney became the youngest driver to win a race in the 18-year history of the Camping World Truck Series by taking Saturday night's American Ethanol 200 at Iowa Speedway.

Blaney, the 18-year-old son of NASCAR veteran Dave Blaney, claimed his first victory in the series in just his third start. He grabbed the lead with 50 laps remaining and then held off the field in four late-race restarts.

The ninth and final caution for an incident involving James Buescher set up a four-lap shootout to the finish. Rookie Ty Dillon challenged Blaney but came up 0.168 seconds short.

Blaney drove the No. 29 RAM for Brad Keselowski racing.

"This is pretty incredible," Blaney said. "I have to thank Brad Keselowski for this opportunity. (Crew chief) Doug (Randolph) made some great calls there at the end. This is pretty unbelievable, so hopefully we can get a few more (wins) here."

Blaney broke Kyle Busch's record of being the youngest winner in the series. At age 20, Busch scored the victory in the May 2005 truck race at Charlotte. Blaney's father attended the race. He is competing in Sunday's 400-mile Sprint Cup Series race at Chicagoland Speedway.

"He did such a great job, and thanks to everybody that has helped him all along the way," Dave Blaney said. "He does so good, because he catches on so quick. It was fun to watch."

With his second-place finish, Dillon grabbed the points lead. The 20-year-old grandson of NASCAR multi-team owner Richard Childress holds an eight-point lead over Timothy Peters, who finished 19th.

"I wanted it bad there at the end," Dillon said. "I was coming, but Ryan Blaney is an amazing driver. I'm glad we didn't have to race against him all of this year. He's a great guy, and he really deserves this. I'm really proud of him."

Todd Bodine finished third, followed by Johnny Sauter and Cale Gale, who is also a rookie in the series this season.

Nelson Piquet Jr., Drew Herring, Jeff Choquette, Matt Crafton and Miguel Paludo completed the top-10.

Parker Kligerman started on the pole and led the most laps with 107, but Kligerman crashed 20 laps from the finish and ended up placing 23rd.
