Typically, teams have a 7-man bullpen and a four man bench. Add that to your 5-man rotation and nine position players, and you have a 25-man Major League roster.
The Toronto Blue Jays could take a road less traveled. MLB.com’s Gregor Chisholm reports that four pitchers are out of options and would have to be passed through waivers before being sent to the minor leagues. Esmil Rogers, Todd Redmond, Luis Perez, and Jeremy Jeffress are all players who could very likely be claimed off of waivers by another team, but the Blue Jays aren’t ready to let go of those assets just yet.
If all members of the projected rotation stay healthy, which most teams will tell you is not something to bank on, then having an extra member in the bullpen would be a way to keep those four names in Toronto. Chisholm also says that the only two players with options were far too valuable in their roles to consider sending them to the minors to create room for the others. Those two are Steve Delabar, winner of the 2013 All-Star game Final Vote, and Aaron Loup, the setup man who has posted a sub-3.00 ERA in his first two big league seasons.
