Hawai'i swept a doubleheader from snake-bit Chicago State in extreme fashion, 20-3 and 3-2, yesterday.

The Rainbows (13-6) had a season-high 25 hits in the opener with Jon Hee batting 5 for 7 with four RBIs. But the Cougars (0-10) couldn't hold an early 2-0 lead in the scheduled seven-inning second game, allowing two of the runs to score on wild pitches.

The closest game of the series at Les Murakami Stadium was watched by 878, who also saw UH coach Mike Trapasso ejected in the top of the fifth inning with the score tied at 2 in the second game after vehemently arguing an out call at first by one umpire that was overturned by another.

"You don't change the call," Trapasso said. "Somebody argues your call, don't go running over to another umpire to over-rule your call. Get the call right the first time. I don't know if (first baseman Kris Sanchez's foot) was on the bag or off. We're back in high school again. You don't go running to the next guy because you're afraid someone's arguing with you. That's ridiculous."

Starter Mark Rodrigues gave up two runs and five hits with one strikeout in 4 1/3 innings. He hit Trenton Sanders to start the fifth. Bryan Packard dribbled out to the pitcher, allowing Sanders to take second. That's when Trapasso pulled Rodrigues for Tyler Davis.

"He didn't have any command today," Trapasso said of Rodrigues. "Because the game was close and we were down and tight, I wasn't going to mess around in a seven-inning game, so we just went with Tyler."

Luke Grow hit a low liner to Sanchez, who had to make a low stab at it. Cougars' coach Vern Hasty argued to no avail that Sanchez trapped the ball. Jonathon Wilson then hit a grounder to third baseman Justin Frash, whose throw to first forced Sanchez to stretch for the ball. First base umpire Dan Farnsworth called Wilson out and the Rainbows departed the field. The Cougars' coaches claimed that Sanchez was pulled off the bag. Farnsworth conferred with home plate umpire Ozzie Ortiz, who signaled that Sanchez was pulled off and safe. Sanders then raced home where no one was covering, setting off Trapasso's loud argument.

When play resumed, Sanders was ordered to return to third. With runners at the corners and Kyle Kupiec at the plate, Davis faked a move to third and fired to first to nail Wilson to end the inning. Davis said he learned the move from a teammate on his summer team in Santa Barbara.

"He taught that move to everyone on the team and it worked like every time we used it," Davis said. "It looks like you're going straight to the plate when (the runner is looking in from) first base."

Davis (2-0) went 2 2/3 scoreless innings, allowing two hits.

In the bottom of the fifth, Robert Vargas (0-3) walked Ryan Asato and Jorge Franco on eight pitches. They advanced on Derek DuPree's sacrifice. With the infield drawn in, Nate Young's ground out to the pitcher held the runners. But Vargas' first pitch to Frash was wild, allowing Asato to score the go-ahead run.

Vargas had the Cougars' best outing of the series, going six innings, allowing three runs, five hits and two walks with one strikeout. He allowed UH's first run on a wild pitch and the tying run on Macdonald's sacrifice foul fly to right.

The Cougars took a 2-0 lead in the second on Mid-Pacific graduate Chris Goya's two-run triple, his first hit of the season after starting off 0 for 17. He and Kupiec were each 2 for 3.

Hasty said it was the fifth time this season his team has given up a lead.

"That's too bad, but in a way it could be a positive because I know we're capable of getting on roll and winning some games," Hasty said.

Trapasso was not pleased with UH's performance in the second game.

"We didn't play well," he said. "We slept-walked through and we were lucky to win. We need to come out tomorrow and play better."

Hawai'i scored in every inning but the third in the opener. CSU starter Mike Wieda (0-3) was tagged for nine runs (eight earned) in 4 2/3 innings.

Hawai'i's Joshua Schneider (2-1) pitched seven innings, allowing a run and seven hits with no walks and four strikeouts. Jeff Soskin gave up a run in one inning and third-year sophomore Harrison Kuroda also gave up a run in one inning in his collegiate debut.

Hawai'i freshman left fielder Kevin Macdonald was 4 for 5 with five runs. Frash, Eli Christensen and Asato each had three hits. All of Asato's hits, including two doubles, came off the bench. He had doubled in four successive at-bats dating to Thursday's game, when he also came off the bench.

Freshman Vinnie Catricala made his starting debut at third base, batting 2 for 6 with two RBIs, while second-year freshman Kevin Fujii made his first collegiate start at catcher, batting 2 for 5 with two RBIs.

Sanchez hit a two-run home run in the sixth, his fifth homer of the season.

The series concludes with a 1:05 p.m. game today. Matt Daly (0-0) will start for UH, while CSU will use Sean Freeman (0-0), who is making his first start of the season.
