McKinley, runners-up of the Oahu Interscholastic Association, advances to today's semifinal game against the University High-Farrington winner, 8 p.m. at Kaimuki.

"It was the best performance we've had in a while," said McKinley head coach Bob Morikuni. "We played how we should be playing."

The Tigers (11-6) set a quick pace early, hitting their first three shots to take a 6-2 lead. Seabury Hall (11-5), Maui Interscholastic League champion, had turnovers on its next four possessions and never recovered. Kasen Dudley's three-pointer ended a 7-0 McKinley run, but the Tigers used a 10-2 run to finish the first quarter.

Julius Borje's layup off the assist from Nainoa Lessary with under two minutes to play in the first half extended the McKinley lead to 33-12.
