Hargrove, 18, from Vancouver, British Columbia, qualified his Cape Motorsports with Wayne Taylor Racing car on the pole position with a lap record and finished the 12-lap race almost seven seconds clear of his nearest challenger.
"I am kind of speechless about how the race went," Hargrove said. "The car was just phenomenal; this whole week has been phenomenal. The Cape Motorsports guys have given me an awesome package. Coming into this week I had a lot of confidence from the Cooper Tires Winterfest, and having a win in the regular season means a lot."
Fellow Canadian Garett Grist drove from ninth on the grid to second, passing Danilo Estrela on the final lap for the runner-up spot. Estrela finished third. Eight different teams were represented among the top-10 finishers.
