FONTANA, Calif. — Home state hero Kyle Larson held off Joey Logano to win Saturday’s Service King 300 NASCAR XFINITY Series race at California’s Auto Club Speedway.
A late-race yellow flag negated Larson’s lead and sent the field pit side for fresh rubber. Larson’s crew kept him out front and he controlled the restart with four laps remaining and held off Logano’s last-lap charge for his first victory of the season aboard the No. 42 Chip Ganassi Racing Chevrolet.
Larson claimed his sixth XFINITY Series victory by 0.127 seconds over Logano. It was Larson’s second victory at the two-mile oval.
“I wish that last caution wouldn’t have come out because it would have been a bit easier for me,” said Larson, who won the pole for Sunday’s Monster Energy Cup Series race. “I didn’t think we would be here yesterday. I was really struggling during practice yesterday, but we really hit on it for the short run today.
“I hope it gives us some good momentum,” Larson added. “Start from the pole tomorrow and hopefully be right back here tomorrow.”
Logano finished second in his No. 22 Team Penske Ford.
“I vote for two races at Auto Club Speedway,” Logano said. “I’ll be the first to say that. What an awesome race track. It’s so much fun. You can run anywhere you want. The racing is great. There is tire falloff. There are bumps. There’s everything here. It’s the perfect race track. I wish we came here more often because it’s the best race track we go to, so I’m excited about racing tomorrow. I’m mad about not winning today is the best way to put it.”
Kyle Busch, who won the first two segments of the 150-lap race, was third in another JGR Toyota. Erik Jones finished fifth in a third JGR entry.
Fifth went to William Byron aboard a JR Motorsports Chevrolet.
There were 18 lead changes among six drivers and seven yellow flags, which ate up 43 laps.
Sadler leads the standings by 17 points over Byron.
