Cole Custer holds off Kyle Busch to win Fontana Xfinity race

Custer held off the all-time Xfinity Series wins leader Busch over the final 14 of 150 laps to earn his first Xfinity Series win of the season and first at his hometown track, Auto Club Speedway.

The win is the third of Custer’s career and he becomes the first series regular to win at Auto Club since Scott Riggs won the event in 2002.

"This win means a ton," Custer said. "To start the year off with a new crew chief and new engineer, they just did a great job. We've just been trying to work through everything and we've gotten a little frustrated with ourselves.

"We wanted to run better than just top-fives and today we accomplished that. We had a great car. Just a great job overall. I'm so pumped - I've never won this early in the season so I'm going to be a little more relaxed then in past years."

In the process, Custer also denied Busch the opportunity to collect his 200th career NASCAR win on Saturday.

"Lack of grip there at the end," Busch said after the race. "We just didn't have the speed we needed with (Custer). Earlier in the day we were better than a lot of guys and at the end, we weren't. Our Supra was fast, just not fast enough at the end."

Christopher Bell finished third, Tyler Reddick was fourth and Custer’s teammate, Chase Briscoe, completed the top-five.

Rounding out the Top 10 Austin Cindric, Brandon Jones, Ryan Preece, Justin Allgaier and Justin Haley.
