The Phillies had added right-handers A.J. Achter and Dan Otero through waiver claims early in the offseason. Since then, the Phillies added players in trades with Houston and Pittsburgh that had to be added to the 40-man roster, making it necessary to designate both Achter and Otero for assignment.
Achter was claimed by the Los Angeles Angels and the Phillies worked out a "future considerations" deal with Cleveland for Otero.
Both pitchers were slated to compete for spots in what will be a greatly revamped bullpen for the 2016 season. The Phillies have continued to sing relievers with major league experience to minor league contracts with invitations to spring training. There is likely to be a fairly spirited competition for spots in the bullpen among both the incumbents from last year's pen and the newcomers who are looking to return to the majors.
