The Coronado Mustangs used a half-court shot to get a game to overtime that they eventually won against Keller to punch their ticket to the Regional Tournament.
Coach Dean's Mustangs took on Keller in Abilene on Thursday night for the right to advance.
Coronado trailed by two in the third, but they found Duncan Douglas down low, and he powered in a bucket, to tie it up at 27.
Keller, answered back when Brock Anders got a lay-up to fall to put the Indians up by four.
But the Mustangs hung around, when Devonte Hutchens pulled up, and hit a jumper. Hutchens would prove instrumental in the fourth quarter with his hot shooting from three and his 40-footer to send the game in overtime where the Mustangs would prevail 55-48, they will play DeSoto on Friday at Daniel Meyer Coliseum.
