So far, so good in Kyle Larson’s first Chase for the NASCAR Sprint Cup.

The No. 42 Chevrolet driver holds the final transfer spot to the Round of 12 by five points over his Chip Ganassi Racing teammate Jamie McMurray heading into Sunday’s Citizen Soldier 400 Chase cutoff race at Dover International Speedway (2 p.m. ET on NBCSN).

Larson finished 18th in the Chase opener at Chicagoland and 10th last Sunday at New Hampshire, but still has some work to do.

“It’s better to be 12th than 13th,” Larson said of his Chase position. “I have a five-point lead on the next guys and I just have to be smart, pay attention to where they are on the race track and just points race really. Hopefully I can transfer to the next round.”

Past history indicates Larson shouldn’t have much trouble on Sunday. He placed runner-up at Dover in the spring and owns two top-five and four top-10 finishes in five starts there for a career average finish of 6.2.

“We always seem to run really well at Dover, so that’s a positive,” Larson said. “We came close to winning there earlier this year. There are probably some things I could’ve done different to get the win. I’m excited to go back. Hopefully our race car has even more speed than it did earlier in the year so I can try to get a win and advance.”
