Cassville then committed back-to-back turnovers, which allowed the Mustangs the opportunity to take the lead. Buttram sunk two free throws with 1:03 remaining to give McDonald County the lead for good.
The Wildcats missed three 3-point attempts in the final 53 seconds, and the Mustangs hit enough free throws at the charity strip to solidify the win.
