A dominant performance from Texas starter Taylor Jungmann was nothing new.

Unfortunately for the Hawaii baseball team, neither was its continued struggle in the field.

An error, one of four in the game, led to Texas’ first run, which was enough support for Jungmann, who tossed a four-hitter in a 2-0 victory over the Rainbows last night at Les Murakami Stadium.

Jungmann (2-0) treated a sold-out crowd of 3,720 to his second straight shutout, striking out nine without a walk. In two games, he’s given up nine hits with one walk and 18 strikeouts.

"It’s a great start, definitely," Jungmann said. "Everything was working today. My changeup was good, both breaking balls were moving and I had pretty good command of my fastball."

Hawaii starter Matt Sisto combined with Blair Walters and Michael Blake to give up one earned run in nine innings.

Sisto (0-1) gave up both runs, but only one was earned. Shortstop Matt Harrison had throwing errors in the first two innings, but Sisto pitched out of it without allowing a run.

With one out in the third, Paul Montalbano hit a grounder up the middle that Kolten Wong fielded cleanly. His throw to first was off the base however, allowing Montalbano to take second on the error.

The sixth-ranked Longhorns (4-2) finally made the Rainbows pay, as Mark Payton hit a two-out single to left to score Montalbano. Payton was thrown out trying to stretch the hit into a double.

The Rainbows (2-3), who lost their third in a row, have committed 14 errors in their first five games.

"We have to play well defensively and if we don’t, we will find guys that will," Hawaii coach Mike Trapasso said. "We’ve made more errors in the first five games of the season than I’m used to making in two months. We have to fix it or find guys that are going to make the plays."

Sisto lowered his ERA to 2.19, but took the loss, giving up six hits and no walks with four strikeouts.

"It was encouraging to go up against a top-five draft pick like that and really battle and give yourself a chance to win," Sisto said. "We were a couple plays away from being 0-0 and felt like we were right there."

The Rainbows got their first hit with one out in the fourth when Wong bunted for a single, beating the throw from third baseman Erich Weiss.

Wong, however, was picked off trying to steal second.

Hawaii got its only runner in scoring position in the bottom of the eighth when Zack Swasey and pinch hitter Sean Montplaisir hit back-to-back singles. After a visit to the mound, Jungmann settled down and struck out Breland Almadova on three pitches.

Hawaii didn’t hit a ball to the outfield until Collin Bennett grounded a one-out single up the middle in the fifth.

Texas scored the first legitimate run of the game in the sixth, taking advantage of a leadoff double by Brandon Loy. With one out, UH tried to bring the infield in, but Weiss lined the first offering from Sisto into center to give the Longhorns a 2-0 lead.

UH continued to shoot itself in the foot when Jeff Van Doornum dropped a routine pop fly to open the eighth. Payton dropped a bunt down the first-base line that Van Doornum fielded, but he couldn’t make a throw to first, putting two men on with no outs. Walters, who replaced Sisto to start the seventh, loaded the bases on a hit batter, but got Jacob Feltz to foul out to third to strand three runners.

Walters allowed one hit and no walks with two strikeouts in two innings and Blake pitched a perfect ninth in his first appearance for the Rainbows.

Hawaii will start Connor Little (0-0, 6.75) in the second game of the series today opposite Texas right-hander Cole Green (0-1, 13.50), the reigning Big 12 player of the year.

"Last time I was here was seven years ago and it’s amazing what (coach Trapasso) and the guys have done with this whole environment," Texas coach Augie Garrido said. "He’s put together a tremendous baseball program and what he’s done to energize the community is pretty special."
