The Eagles (7-5) went 5-5 during their eight-day trip to Arizona.
Gibson, a right-hander from Appleton, Wis., allowed one run on seven hits with no walks and improved to 2-0 this season. Also for the Eagles, Mike Schmidt hit two homers, Dusty Otto went 4-for-4 with a homer and a double and Storm Gram doubled twice.
UW-L's home opener is scheduled for 3 p.m. Wednesday against Saint Mary's (Minn.) but Eagles coach Chris Schwarz said it's unlikely the field will be ready in time because of the recent snowstorm.
