Cameron Wheeler went 4 2/3 innings, allowing two runs, eight hits and two walks with four strikeouts. Although he left with the lead, he did not go the minimum five innings to get credit for the win. Kramer got credit for his second win of the season in a relief situation where the starter could not reach five innings. He allowed two hits and struck out seven.

Sean Murphy (0-1) allowed six runs, 10 hits and three walks with five strikeouts in six-plus innings for the Cougars (0-8).

The Rainbows took a 1-0 lead in the second. Brandon Haislet led off with a walk, took second on a passed ball, and scored on Kris Sanchez's single off a diving second baseman Alex Hall.

Hawai'i increased its lead in the third. Jon Hee and Justin Frash hit successive singles, and both scored on Haislet's triple to right-center. Sanchez's flair single to right-center score Sanchez to make it 4-0.

The Cougars got a run in the fourth when they had three successive singles to load the bases, setting up Kyle Kupiec's sacrifice fly to right to make it 4-1.

Chicago State cut its deficit in half in the fifth. With two outs, the Cougars loaded the bases with two singles and a walk followed by Murphy's RBI single to left to end Wheeler's night. Jayson Kramer came in to retire Kupiec on a fly to left to end the inning with the bases loaded.

The Rainbows got the run back in the bottom of the fifth. Hee led off with a single, took second when Frash grounded out to first and after Haislet grounded out to short, scored from second on Sanchez's double to left-center to make it 5-2.
