Arizona starter J.C. Cloney twirled a four-hit shutout (six strikeouts, three walks), and second baseman Cody Ramer reached base four times and scored twice.
Cloney's outing was particularly big since the status of Wildcat ace Nathan Bannister (forearm) is uncertain for the CWS final. So the bullpen got a much-needed night off.
The run-suppressing nature of TD Ameritrade Park in Omaha was apparently in the late innings, as a pair of Coastal Carolina deep drives that looked good off the bat wound up dying at the track.
The win puts Arizona on the brink of their second national championship in the last five years.
The two teams meet in an elimination game for Coastal Carolina tonight. Game 3 if necessary is Wednesday.
