Pike pushed its lead to 44-35 midway through the third quarter, but the Arabians never relented. When Buck somehow got a three-quarter court shot to fall at the buzzer, pulling Pendleton Heights within 46-43, it seemed anything might be possible.
Kenton Dunham — one of four Arabians in double figures with 10 points — tied the game 50-50 with a 3-pointer at the 5:02 mark of the final period.
Jalen Morgan — who scored all of his game-high 16 points in the second half — made a traditional three-point play at the other end to ignite a 7-0 run for the Red Devils.
A jumper by Dunham and a 3-pointer by Buck got the Arabians back to 57-55 with 1:09 to play. Buck then tipped a Pike pass at mid-court, and Austin Brizendine pulled it down and sprinted to his basket. He was fouled at the rim and made one of two free throws to make it a one-point game.
Morgan added a pair of charity shots with 13.8 seconds left to put back ahead by three at 59-56, and Pendleton Heights got one final chance. The ball was knocked away on the inbounds pass, however, and Morgan added another free throw with 9.6 seconds remaining to provide the final margin.
Justin Thomas added 14 points for Pike, and Tahjai Teague — whose father, Sean, played at Anderson High School — finished with 13.
Caleb Hardy scored 12 points for the Arabians, and freshman Mark Albers added 11.
Pendleton Heights next will play Anderson in the first round of the Madison County tournament on Monday.
Hahn said games like Thursday night's are just what the Arabians need to get better.
"Obviously, Pike is an elite program," he said. "It gives us an idea of exactly where we're at."
