The Cal Poly baseball team’s night to remember was Hawaii’s nightmare to forget.

Alex McKenna had four hits, including a solo homer in the second inning, to lead a 14-hit attack and senior left-hander Trent Shelton pitched the first complete game of his collegiate career in the Mustangs’ 16-0 rout on Friday night.

From the opening walk to an eight-run, 13-batter ninth, everything went the Mustangs’ way. They also drew 10 walks, were plunked three times and benefited from four Rainbow Warriors errors.

“It was our worst loss in 17 years, and it’s all on me,” UH coach Mike Trapasso said. “It was the worst coaching job I’ve ever done. Obviously, I didn’t have the guys ready to play. It was a horrible coaching job.”

In dropping to 22-18 overall and 8-8 in the Big West, the ’Bows ran their scoreless streak to 19 innings. They have lost four of their past five games.

The ’Bows entered short-staffed, with three pitchers who combined for 29 starts — Neil Uskali, Dominic DeMiero and Logan Pouelsen — ailing and unavailable to pitch this weekend. UH’s wish was starter Jackson Rees would pitch effectively and economically to spare the bullpen.

But Rees was ousted after four innings, allowing six runs, six hits and three walks.

“The ball got away from me,” Rees said. “I found the (strike) zone, they hit it. I didn’t find the zone, they didn’t swing at it. They were clearly on their game today. Hitting-wise, it was the same as last year. It seemed like they saw my ball really well, saw it out of my hand. Maybe I’m tipping something. They figured it out.”

And the ’Bows could not solve Shelton, who allowed five hits and a walk. It was the best pitching performance for Shelton, who started his career at Oregon State.

Shelton said he gained control of a two-seam fastball and a slider. “They were rolling over (the slider),” Shelton said. “And look at the plays we made tonight. We had great defense. I relied on them, and they made every play. That was great.”

The most highlight-worthy came on Alex Baeza’s hard smash up the middle. Shelton deflected the ball with his glove. Second baseman Scott Ogrin made a bare-handed pickup, then fired sidearm to first baseman Tate Samuelson for the out.

“It was a great crowd and great energy,” Shelton said.

It did not take long for the Mustangs to reduce the ’Bows’ golden rule — do not walk the first batter of the inning — to fool’s gold.

Rees issued walks to the first two Mustangs in the first inning. McKenna scored the game’s first run on Samuelson’s single down the left-field line. Two outs later, it was 3-0 after Kyle Marinconz and Samuelson came home on Bradlee Beesley’s single to right-center.

The Mustangs added a run in the second when McKenna’s opposite-field drive ricocheted off the right-field pole for his fifth home run of the season.

In the fourth, the Mustangs loaded the bases when Beesley singled, Elijah Skipps walked, and Ogrin singled. Beesley scored on a double-play grounder, and Skipps came home when third baseman Eric Lopez threw wide at first on McKenna’s infield single.

In the fifth, Nick Meyer reached when he was struck by a pitch, went to second on a balk, and scored when Beesley lined a single off the glove of second baseman Dustin Demeter.

With two outs in the seventh, Skipps walked and Ogrin was hit by a pitch. Dylan Doherty followed with a run-scoring double to left-center.
