The Buffanblu, ranked No. 2 in The Advertiser's statewide Top 10 poll of coaches and media, finished the regular season at 11-1, a game ahead of the No. 1-ranked Raiders (10-2).

Both teams have secured berths in the state tournament set for Feb. 20-23, but Punahou will also receive a first-round bye in the 12-team field.

Ostrowski, a 5-foot-9 point guard, finished with a season-high 26 points to go along with seven assists, four steals and two rebounds. He scored 18 points and had five assists and all four of his steals in the second half, during which the Buffanblu stretched a 26-20 halftime lead to 41-24 with 1:33 remaining in the third period.

"It feels good, this was a tough game till the end," said Ostrowski, also a two-time All-State receiver who signed a letter of intent Wednesday to play football for the University of Hawai'i. "Even when we were up (by) 15, I knew they could still hit a couple threes and get back in it. I was tired, but we just kept pushing."

Bricen McCartney's 3-pointer cut it to 52-43 with 2:01 left in the game, but Kameron Steinhoff's free throw 30 seconds later pushed the lead back to 10 and Ostrowski connected with Henry Cassiday on a perfect alley-oop play with 1:13 remaining to make it 55-43 and effectively seal the victory.
