After a steal by Walker Whitworth, Henderson scored again to give Ada its first lead since the third quarter at 53-52 with 2:05 left.
Seminole’s Xavier Freeman scored after missing two previous shots but pulling down both rebounds to give the Chieftains a 54-53 advantage with 1:51 remaining.
After Henderson missed the front end of a one-and-one, White drained two free throws with 36 seconds remaining to give Seminole a 56-53 cushion. But Henderson drained a 3-pointer off an assist from Whitworth with 18 ticks left to knot the score at 56-56. Henderson would lead the Ada offense with 17 points.
White would drive to the basket with :05 showing and went to the free-throw line after Henderson attempted to draw a charge. He made the second of two free shots to break the deadlock.
After an Ada timeout, David Forbes took the inbounds pass and handed the ball off to Whitworth, who was streaking down the far sideline. The Ada sharpshooter got a good look at a 3-point shot at the buzzer, but he couldn’t connect as Seminole hung on for the dramatic victory.
A fast-paced first quarter saw both teams sizzle from the field, hitting 7-of-12 field goals apiece. Seminole led just 18-17 late in the first quarter, but Seminole big man Jayce Cravens scored eight unanswered points of his own to put the Chieftains on top 26-17 with just under seven minutes left in the second period. Cravens led all scorers with 21 points to go with nine rebounds.
Anderson said giving up that many points in nine minutes of game time has to stop.
“That’s not acceptable," he said. “The only word I can think of to describe that game was disappointing. It’s obvious we can score, and we haven’t had that problem all that much all year long.
