A familiar story line had another grim ending for the Hawaii baseball team in Saturday’s 3-2 loss to Cal Poly in San Luis Obispo, Calif.

Before 1,741 at Baggett Stadium, the Mustangs won the first two of this three-game series. Since the Rainbow Warriors’ inaugural Big West season in 2013, the Mustangs have won all seven series between the teams, holding a 16-4 edge.

On Saturday, the ’Bows made too many mistakes and offered too little support for starting pitcher Aaron Davenport. The ’Bows failed to parlay 10 hits into more runs. The ’Bows have scored four or fewer runs in five of the past six games in which they amassed double-digit hits.

“That’s kind of been a little thorn in our side the last few weeks,” UH coach Mike Trapasso said. “We get 10 hits and two runs, and we’ve only scored in one inning (in each) of two straight games.”

The ’Bows stranded 11 runners, including two in the ninth when Michael Clark induced Ethan Lopez to fly out for his second save in as many days.

“We haven’t been pitching well, and then we do, we don’t pick it up in other phases,” Trapasso said.

The ’Bows gifted two runs to the Mustangs. With two outs in the second inning, third baseman Dallas Duarte fielded a grounder but threw past first baseman Alex Baeza, allowing Tate Samuelson to score the game’s first run.

With the score tied at 2 in the fifth, Samuelson drew a two-out walk and went to second on Conagher Sands’ single. Then Nick DiCarlo lofted a towering fly that was airborne for seven seconds. The ball landed between left fielder Daylen Calicdan and shortstop Lopez as Samuelson scored the tie-breaking run.

“The ball has to be caught,” Trapasso said. “We misplayed two balls in the outfield. We made two errors on the infield. In reality, we made four errors, home-town scoring besides the point. Those were errors on plays that had to be made and they cost us two runs. You couple that with scoring only two runs, and scoring in only one inning two games in a row, and that makes it hard. The reality is we should have won that game, 2-1.”

The ’Bows wasted one of Davenport’s best outings in recent weeks. The freshman right-hander allowed three runs — two earned — in six innings. Davenport added the change-up to his menu of fastballs and curves.

“We really utilized the change-up more than he ever has,” said Trapasso, who calls the UH pitches. “That’s a pitch you’ve got to be able to throw against these guys. He’s normally fastball (and) curveball. For him to grow as a pitcher and be the guy we think he is, he needs to be a three-pitch guy. And the change-up is the pitch you’ve got to be able to throw. … Aaron deserved a better fate. I think we sabotaged him on defense today.”

The ’Bows were not whole on Saturday. Duarte tweaked an ankle on Friday, necessitating his move from second base to third. “Dallas is going to stick his nose in there and give you his best effort,” Trapasso said.

Lopez played short in place of Maaki Yamazaki, who continued to experience discomfort in his right (throwing) arm. Yamazaki started at designated hitter, going 2-for-4 with a walk. That meant Brennen Hancock, the usual designated hitter, was left off the lineup card.

“We had to choose between (Hancock) and Maaki,” Trapasso said. “Maaki was getting on base, but not having both in the lineup, you’ve seen what happened to us.”
