They were the third and fourth wins of the season for Philpott, who will move up in the NASCAR Whelen All-American Western Late Models points standings right behind his son, Justin.
Justin has one win this year, but has finished in the top five in eight out of 11 races to put him in second place overall. Vito Ranuio of Modesto leads the Stockton 99 standings in the Western Late Models.
As David Philpott took the wire-to-wire win in the first 50-lap race. Justin and Ranuio looked for a chance to take the lead before they tangled at the end of the race to give David Philpott the win under a yellow flag. Second place was Katie Hagar, Mike Wendt was third, Ranuio fourth and Justin Philpott fifth.
Ranuio took the early lead in the second 50-lap race, but he and Katie Hagar spun out on Lap 17, which gave David Philpott his chance to move to the front. Ranuio was ejected from the race on Lap 27 after race officials blamed him for another crash. Hagar again finished second, Mark Holman third, Justin Philpott fourth and Wendt fifth.
Tracy driver Scott Winters took his second win in a row in the Grand American Modifieds. Persistence paid off for Winters as he worked his way through the crowd and held on through multiple yellow flags to take first place.
