An ensemble pitching effort helped the Hawaii baseball team assemble a 5-2 nonconference victory over San Diego at Fowler Field on the USD campus Wednesday.

In a so-called “staff” game, in which it was predetermined the Rainbow Warriors would use several pitchers, 10 hurlers gave up a combined 11 hits to the Toreros. But the ’Bows turned four double plays, and issued only two walks. After Colin Ashworth, UH’s ninth pitcher, yielded two hits, including a solo homer in the ninth, Dylan Thomas was summoned for the final out.

“Overall, the guys were throwing strikes,” said UH coach Mike Trapasso, appeasing early concerns. In the first inning, Trapasso noticed home plate umpire Joshua Brenner had a narrow strike zone.

“I had a concern it was going to be an interesting game from a pitching perspective just because I thought the zone was really tight,” Trapasso said. “It stayed that way, and it was consistent all night, but it was a tight zone. For us to walk only two guys with the way the zone was, I was impressed with our guys.”

But the ’Bows found the zone on 61 percent of their pitches, and induced 14 grounders. The first eight pitchers — starter Li‘i Pontes to Jeremy Wu-Yelland — pitched an inning. None of them threw more than 18 pitches. Trapasso was hesitant to use his two best relievers, Wu-Yelland and Thomas, but relented after their gentle prodding.

Trapasso recalled: “Both of them came up to me and said, ‘if we don’t throw an inning, we’d like to throw a bullpen (session) because we feel really good and want to throw.’ We went ahead, when the situation presented itself in the eighth (for Wu-Yelland) and ninth (for Thomas). It was a perfect situation for them.”

Trapasso said each of Wednesday’s pitchers will be available for the weekend series against Cal State Northridge. The ’Bows resume Big West play with Friday’s opener.

“Everybody’s good,” Trapasso said. “That’s why we only threw everybody an inning.”

UH shortstop Maaki Yamazaki scored two runs on Ethan Lopez’s RBI single in the opening inning and sacrifice fly in the third.

In the sixth, the ’Bows manufactured their third run when Daylen Calicdan was hit by a pitch, went to second on Dallas Duarte’s groundout, scooted to third on a wild pitch, and scored on Jack Kennelly’s single to left.

The ’Bows added two runs in the ninth on a bases-loaded passed ball and Kennelly’s sacrifice fly.

Kennelly started at second base when Duarte filled in for catcher Tyler Murray, who is suffering from a hamstring ailment.

“I thought Jack Kennelly had a nice game,” Trapasso said. “He really helped us out offensively, and made a couple nice plays in the field. I was happy for him.”

Kennelly also showed grit when he bunted a ball off his nose.

“It knocked him for a loop a little bit,” Trapasso said. “It gave him a pretty good cut on the bridge of his nose. That spot on the bridge of the nose is hard to stop bleeding.”

Kennelly remained in the game, leading to his RBIs.

Yamazaki, Lopez and designated hitter Brennen Hancock each had two hits. Hancock also surprised the Toreros with two steals. He also showed deceptive speed in advancing on a wild pitch.

“He had a good game,” Trapasso said of Hancock, who has hit safely in 14 of the past 15 games. “There’s no doubt he’s a good player.”
