The Pirates have some tough roster decisions coming up next week, and will need to create some room on their 40-man roster in order to bring up all of their best options. Some of the guys who are good candidates to get called up include Vance Worley, Radhames Liz, Pedro Florimon and Travis Snider. None of those guys are currently on the 40-man roster.
The only problem with creating 40-man spots is that there aren't many candidates to come off the roster at the moment. There is currently one spot open on the roster, but the Pirates would need at least three more spots to add the three guys above.
