HONOLULU — Isaiah Stewart had 26 points and 13 rebounds to lead No. 21 Washington over Hawaii 72-61 in the Diamond Head Classic semifinals Monday.
Quade Green added 11 points and seven assists for the Huskies (10-2), who will play Houston for the tournament title on Wednesday. Jaden McDaniels had nine points and 13 rebounds, and Nahziah Carter chipped in with 10 points.
Stewart made 13 of 21 shots from the field. He scored 16 points in the first half and finished with his fourth straight double-double.
Hawaii got within six on Zigmars Raimo’s basket in transition with 5:28 to play, but went scoreless for more than three minutes while the Huskies reeled off an eight-point run to stretch their lead to 59-45 with 2:04 remaining.
Justin Webster had 16 points and Raimo added 15 points with 15 rebounds to lead the Rainbow Warriors (8-4), who shot a season-low 28%.
The Huskies dominated in both points in the paint (40-18) and fast-break points (24-9).
Washington led 37-22 at halftime.
Washington is off to its best start since the 2014-15 season, when it opened 11-0 before dropping its next four games. The Huskies, who have won eight of nine, were picked to finish third in the Pac-12 preseason media poll. They open conference play against UCLA at home on Jan. 2.
Hawaii has yet to reach the title game of the Diamond Head Classic in the 11-year history of the tournament. Hawaii finished third in the 2014 and 2015 editions of the annual eight-team field. The Rainbow Warriors were picked to finish fourth in the Big West in a preseason media poll.
Washington: The Huskies own a 5-2 advantage over Houston all-time. The teams last met on Dec. 24, 2004, which resulted in a 110-63 win for Washington.
Hawaii: Will face Georgia Tech for third place Wednesday. The teams have split four meetings and last met in 1973, when the Yellow Jackets pulled out an 85-82 home win over the Rainbow Warriors.
