The Wolves got a pair of free throws from Macy Gunderson and Mikey Heikens to ice away the victory in the final 60 seconds.
Both teams traded leads in the seesaw battle with CC-E leading at halftime, 22-21, but trailing after three quarters, 30-26.
Harris-Lake Park assistant coach Becca Boda said that the Wolves' defense held CC-E's two standouts, Emily Jobst and Blair Montgomery, in check defensively with a mix of zone and man-to-man.
"We played a triangle-and-2 defense where we had one girl on Montgomery and one on Jobst and we did go back to man as well," she said. "Our defense was pretty good and on offense we drove it to them. They kept fouling us and we hit our free throws. I'd have to attribute the win to us making our free throws in the last minute of the game."
The H-LP defense held the Mavs to 13-of-58 shooting (22 percent), including 3-of-14 for Jobst, 1-of-10 for Heather Busch, and 0-of-11 for Mattie Larson.
Montgomery led with 14 points and 13 rebounds. Jobst finished with 11 points and five rebounds. Four Mavericks finished the game with four fouls and Stevie Scott fouled out.
Noreen Morrow recorded a double-double with 17 points and 13 rebounds, including seven offensive. Mariah Gath chipped in 14 points, three assists and two steals.
The Wolves moved into three-way tie for first place in the Cornbelt with the victory, improving to 3-1. Harris-Lake Park is now 6-3 overall. Clay Central-Everly falls to 2-2 in the league and 6-2 on the year.
