An extra four minutes on the court was a minute amount time for Academy of the Pacific.

Having spent an entire season with the same core of players on the floor, the Dolphins were accustomed to lots of playing time. Last night, the extra four minutes in overtime signified another chance to prove the Dolphins belonged in the Hawaiian Airlines Boys Basketball Division II State Championships.

"We had to play the whole season without (much) subbing," said Micah Dunhour, who had 21 points and 14 rebounds to lead AOP to a 60-57 overtime win over second-seeded Seabury Hall in a quarterfinal game at Kalani. "No one pretty much believed in us ... thought we could make it here. But we played hard."

Four of AOP's starters played the entire 36 minutes last night while a fifth starter played the entire game except for the final second of overtime. The Dolphins (16-3), who have about 100 students in grades 6 through 12 at their 'Ālewa Heights campus, rallied from a nine-point fourth-quarter deficit to advance to play defending champion Kailua (14-4) in today's 7 p.m. semifinal at Kalani. Simon Koch had 17 points and David Daniels added 14 in the win.

Pāhoa (7-9) will meet Kapa'a (12-2) in a semifinal game at Farrington as all four seeded teams lost yesterday.

"We just got to believe in ourselves, listen to our coaches, use our head, know we could win, know we're good enough to play with these kind of guys," Dunhour said.

Seabury Hall (10-1) missed three 3-point attempts with less than 10 seconds remaining, the last attempt by Michael Palmer from the top of the arc as time expired.

Palmer finished with 24 points and Phelan Pagano added 16 for the Spartans. David Dunn had 11 rebounds in the loss and Dylan King had nine points coming off three dunks and a 3-pointer.

Koch hit two free throws to put the Dolphins ahead 59-57 with 31.6 seconds left in OT and Dunhor hit a free throw with 17 seconds for a 60-57 lead.

"That was the only thing I focused on," Koch said of the free throws. "I knew I would make them."

The game was tied at 55 at the end of regulation.

"That kind of determined the pace and coach just wanted us to keep it up and keep putting the pressure on them," Kailua's Jordan DeCorte said of his team's 11-0 start.

St. Joseph rallied behind seven 3-pointers to tie the score at 41 with 6:55 to play.

DeCorte's jumper and 3-point play extended Kailua's lead to 48-44, but Jacob Andrade's steal and layup cut the deficit to 48-46 with 2:34 left.
