“We played pretty well defensively,” Grain Valley coach Randy Draper said. “Struggled offensively for a while, then got going.”

The Eagles led 12-7 after one quarter and extended the advantage to 28-10 by halftime with a 16-3 run in the second quarter.

Keely Hill dominated the board with eight rebounds as the Eagles (8-3) advanced to Wednesday’s 6 p.m. semifinal against Odessa.
