The Lady T-Birds beat Evanston 53-50 in overtime to advance to the semi-finals in the State tournament.
Mackenzie Fagenbush led East with 16 points and 9 rebounds.
It was a back-and-four affair with 6 lead changes and 5 ties, but the Lady T-Birds' six points in overtime put East over the top and secured the win.
East's head coach, Rusty Horsley, said his team not only won with skill, they won with heart.
Horsley said, "Really proud of the girls I think it's just grit and toughness. Evanston's a great team, they're very fundamental and they were more fundamentally sound than we were but our kids just showed a tremendous amount of heart."
