Hawaii tied it in the bottom of the inning when Breland Almadova scored on an error by the Pilots, who couldn’t come up with a two-out ground ball up the middle by Zack Swasey.

Portland had runners on second and third with two outs in the ninth when Jeff Van Doornum couldn’t scoop a low throw by Matt Harrison at first, allowing both men to score.

Chet Thomson followed with an RBI single to give the Pilots a 10-7 lead.

Kolten Wong, who made his first collegiate start at catcher, finished 4-for-5 with two doubles and two RBIs.
