Jordan Richartz homered twice and drove in a career-high five runs and Alan Baldwin added a solo homer of his own as Hawaii crushed Pepperdine 15-8 in the opener of a four-game series at Eddy D. Field Stadium in Malibu, Calif.

UH (5-5) homered three times in a game for the first time since March 13, 2011 against Portland. Richartz became the first Rainbow with a multi-homer game since Collin Bennett hit two against Sacramento State on May 11, 2012.

Eric Ramirez added two hits and four RBIs and Kaeo Aliviado singled and scored twice to extend his hitting streak to six games. UH won its first road game of the season for the first time since 2009.

Matt LoCoco became the first UH player to get hit with a pitch three times in one game as Pepperdine hit six UH batters total.

UH finished with 13 hits.

Tyler Brashears (2-1) allowed five runs (three earned) on eight hits in five innings with no walks and four strikeouts to earn the win. Reliever Michael Perri (0-1) recorded only one out and gave up four runs on three hits to take the loss for the Waves (4-5).

Recent Punahou graduate Bo Coolen, son of UH softball coach Bob, pitched a scoreless ninth inning in his collegiate debut with one walk.

Konawaena alumnus Kolten Yamaguchi started at catcher for Pepperdine and was 0-for-5.

Hawaii trailed 5-2 in the sixth inning when Baldwin led off with his first career home run. Ramirez gave UH a 6-5 lead with a two-run single and Richartz followed with a three-run homer to make it 9-5.

Hawaii scored seven runs in the sixth and five more in the eighth, which was capped off by Richartz’s two-run blast to left.

The series continues Friday at noon.
