On Thursday, the New York Mets announced manager Mickey Callaway would not return for a third season. Callaway's dismissal is the fourth managerial firing of the winter. Add in the Chicago Cubs permitting Joe Maddon to become a free agent and both Bruce Bochy and Ned Yost retiring, and there are now seven managerial posts open across the land. "We want to thank Mickey for his consistent work ethic and dedication over the last two seasons and I'm certain these characteristics will serve him well in his next opportunity," Mets general manager Brodie Van Wagenen said. "A decision like this is never easy, however, we believe it is in the best interest of the franchise at this time." Callaway guided the Mets to an 86-win season that featured too many highs and lows to count, from a 46-26 second half to a confrontation with a reporter that precipitated Jason Vargas's banishment to the Phillies. In all, Callaway posted a winning record with the Mets -- which makes it odd that his removal seemed like a matter of when rather than if.
