Manager Walt Weiss said he found out about Morales on Friday afternoon and there wasn't time to get another starter to town. The team's Triple-A affiliate is down the road in Colorado Springs, but the Sky Sox are in Sacramento for a series.
Weiss is hoping Belisle can last three innings and then turn things over to the bullpen. Weiss said he's going to ''improvise a little bit.''
The Rockies may have Morales available as a reliever on Saturday.
