Washington is in line to possibly take home the 3A state title, and behind this season’s success is a group effort, but Mazzy stands out. If a big play needs to be made, you can definitely count on her to pull through, and if someone has to take the big shot, she won’t hesitate to be that player. She notched 1k points earlier this month, and she is nowhere near done adding to that total.
