Gamboa (1-0) pitched 3 1/3 scoreless innings, allowing a walk and hit batsman for the Aggies (7-7, 1-1), a provisional Division I program.

A crowd of 903 attended the three games at Les Murakami Stadium.

"We're not hitting, period," said an angry UH coach Mike Trapasso, moments after tossing a glove and kicking a bucket in the dugout. "We're not hitting. If I ... knew, we'd hit."

The Aggies scored a run in the top of the fourth against UH starter Myles Ioane when Matt Dempsey led off with a single, stole second on a called third strike to Daniel Descalso, and scored on Lukas Kirby's RBI single to right.

Ioane, making his starting debut, went only four innings, allowing the run on four hits and no walks with four strikeouts.

"He was on a 50-pitch count," Trapasso said. "His elbow got sore."

Ioane, a freshman left-hander out of Waiakea High on the Big Island, used 49 pitches, got four grounders for outs, including a double play and three air outs.

Dean Turner (0-1) was tagged for two runs on four hits and two walks with one strikeout in 2· innings of relief. He gave up a run in the fifth when Sean Rooney led off with a single, took second on a sacrifice, and scored on David Huffman's ground single to center that made it 2-0.

The Rainbows tied the score in the sixth, breaking 13 consecutive scoreless innings stretching from Tuesday's 13-inning loss to Sacramento State. Only a bobbled ground ball with one out and a runner on first prevented a possible inning-ending double play allowed UH to score.

Schafer Magana led off with a single, but Isaac Omura struck out. Luis Avila then hit a grounder to shortstop Brandon Oliver, who bobbled the ball, but still got Avila at first, as Magana took second. Matt Inouye's single to center scored Magana and the throw home allowed Inouye to take second, where he scored on Rocky Russo's double to right to tie the score at 2.

The Aggies regained the lead in the seventh. With one out, Oliver singled to right-center and took second when Dempsey bunted out, pitcher to first, against Turner. Left-hander Kyle Thomas was brought in to face the left-handed hitting Descalso, who grounded a single to right to score Oliver. Thomas struck out Kirby to end the inning.

The Rainbows' failure to execute was prevalent throughout the game. Magana led off the eighth by getting hit by a Gamboa pitch. But Omura popped out to the pitcher on his bunt attempt. Avila then grounded into an inning-ending double play.

It was the second failed bunt attempt in the game. In the third, freshman catcher Erik Ammon got his first collegiate hit, a ground single to short. Derek Dupree offered to bunt and missed on the first pitch and eventually struck out. The next two batters made outs, stranding Ammon at first.

Also, 13 of UH's 27 outs were air outs; one was a liner.

In the UH ninth, Ryan Asato drew a two-out walk to put the tying run on base, but Ammon fouled out to the catcher to end the game.

The Rainbows will play South Florida in tonight's scheduled 6:35 start. The Bulls are 1-1 in the tournament.
