Corey Day holds off Jesse Love to win NASCAR O'Reilly Series race at Charlotte

Allgaier won the final race off pit road and held the lead until there were 18 laps to go, when he slipped and hit the wall in turn 2, allowing Love to take the top spot. Day then passed Allgaier for second, though the final caution of the night re-racked the field one more time and gave Day the shot he needed. 

Day rebounded after he incurred a pit road penalty early in the race for driving through too many pit boxes.

"The 2 got really loose from what I could see in front of the 7," Day told the CW. "I think that messed them both up. That was enough for me to get a good run off of it and take my run. It hink if I don't do that, then I don't win a race. What a job by my guys. I screw up... to have the car to do that... just so cool."

Day has made up 85 points in the championship over the last two races and is third in the standings, seven points behind leader Sheldon Creed with four races to go in the season. Love is second in the standings and two points back of Creed, while Allgaier is fourth and 15 points behind Creed for the top spot.
