In celebration of Sunday’s outcome, “bottoms up” would be a fitting cheer for the Hawaii baseball team.

The Rainbow Warriors’ sixth-through-ninth hitters were a combined 12-for-15 — led by left fielder Daylen Calicdan’s 5-for-5 — in a 13-6 rout of UC Davis before 1,121 spectators at Les Murakami Stadium.

By winning twice in this three-game set, the ’Bows won their second series of the season to improve to 13-17 overall and 3-3 in the Big West. The Aggies fell to 10-14 and 3-3.

“It was a series win, which we haven’t had in a while,” UH coach Mike Trapasso said. “It’s been a month since we’ve had one of those. It’s been encouraging and disappointing, but we’ll stick with encouraging.”

For the ’Bows, solid starting pitching, purposeful hitting and a chicken taquito were the key ingredients.

The ’Bows entered with a specific plan against UCD left-hander Chris Brown, whose fastball tops in the mid-80s. “We knew there wouldn’t be power arms,” UH catcher Tyler Murray said of the Aggies’ starting pitching. “We had to change our approach to middle away and working the (center-to-opposite) part of the field. If (Brown) came inside, we were quick enough to get that inside pitch and pull it.”

Calicdan placed singles to right field and center field, and two doubles into the left-center gap and another two-bagger down the left-field line.

“It was trusting the game plan, and not getting away from it,” right-swinging Calicdan said. “Sometimes when you get two hits early, you try to do too much on the next (at-bat) and try to hit it harder. I didn’t try to do that. I stayed on top of the ball. … I shifted my sights to the opposite side of the field and good things happened. I let the (pitch) get a little deeper on me. In case I was early, I still had room for error on (the left) side.”

Calicdan, who now leads the ’Bows with a .319 average, said he was fueled by a pregame peanut butter protein bar and a chicken taquito. “My Sunday meal,” Calicdan said.

After the Aggies closed to 3-2 with single runs in the fifth and sixth innings, the ’Bows answered with a three-run sixth. Those UH runs came when Calicdan, Dallas Duarte, Murray and Tyler Best hit back-to-back-to-back-to-back doubles.

Duarte’s two-run double sparked the ’Bows’ five-run seventh.

Duarte went 2-for-4 with four RBIs, Murray had three hits and a walk in four plate appearances, and Best contributed two hits and drove in two runs.

“When you’re getting production from the bottom of the order, like we did today, you have a chance to win most games,” Trapasso said. “The 6 (Calicdan) and 8 (Murray) holes were on base every single time. You have a chance to blow out guys if that happens.”

Logan Pouelsen was resourceful in his second consecutive start. Two weeks ago, he allowed an earned run in seven innings against Ohio State. On Sunday, Pouelsen allowed three earned runs and spaced eight hits in 62⁄3 innings, but did not issue a walk, to improve to 2-0.

During a pregame warm-up session, “he didn’t miss a spot,” Murray said of Pouelsen, his Huntington Beach (Calif.) High teammate. “He was untouchable.”

In the game, Pouelsen used a two-seam fastball and slider to induce 16 groundouts. “It started with Logan being really good,” Trapasso said. “This was a dogfight going into the sixth inning. He kept us in it. For us to get the three in the sixth inning was really big. We separated from that point on.”

Trapasso said he is hopeful starting pitcher Cade Smith, who was struck on the right thigh by a liner on Saturday, will be available for this coming weekend’s road series against UC Riverside. Trapasso also said first baseman Alex Baeza, who was struck on the face with a helmet that fell off a UCD base runner, has entered the concussion protocol.

“We’ll have to wait and see,” Trapasso said.
