After leading by 17 at the half, Williamstown (14-10) outscored Tucker 16-10 in the third quarter and through foul shots, Tucker turnovers, and 3-pointers, Williamstown was able to chip the Mountain Lions lead all the way down to two in the first few moments of the fourth.
But percentages don't lie and in the first half Tucker made 51.6 percent of its shots compared to just 21.2 for Williamstown including 1-for-14 from 3-point range, many of them open looks resulting in a 36-19 halftime deficit.
Even though the Yellow Jackets roster lists seven seniors compared to just two for Tucker, it was the Mountain Lions that grinded through, making plays when they absolutely had to be made late in the game.
Kenzie Stephanie Betler scored 29 points and grabbed 12 rebounds for the Mountain Lions while Amber Evans had 21 points and 12 boards. In all, Tucker held a 51-37 advantage on the glass.
Kenzie Smith led the way for Williamstown with 19 points and Brooke Cieslewski had 16.
The Mountain Lions will take on No. 1 St. Joseph at 1 p.m. on Friday in a Class A semifinal game.
