The Cougars had no answer for Rockets guard Nakayla Ehrhorn, who poured in a game-best 38 points, including 25 in the second half to lift Castle Rock to the 1A Trico League road victory.
Ehrhorn, a senior, had 13 of her team’s first-half points and finished with 18 of 26 at the free-throw line and also hit four 3-pointers on her career night.
“She was pretty much unstoppable,” Seton assistant coach Jason Otto said.
Jasmine Morgan led Seton with 16 points.
