Rea was recalled from the Cubs' alternate camp site Thursday, Patrick Mooney of The Athletic reports.
EDGE Analysis
Rea will replace Dillon Maples on the roster and in the bullpen. The right-hander spent all of last season with Triple-A Iowa, posting a 3.95 ERA and 1.36 WHIP across 26 starts (148 innings). He'll likely provide length out of the bullpen for the Cubs.
