Piecing this together from all over the place: The initial rosters listed only two Pirates: Brock Holt and Robbie Grossman. It was then announced that the Pirates would send one more position player and four pitchers. Today the AFL Twitter (linked above) reported that the Pirates will also be sending Nate Baker, Mike Colla, and Phil Irwin. Kristy Robinson then reported that Jarek Cunningham was the third position player. Rob Biertempfel took the pitcher announcement to mean that Gerrit Cole would not be going, but Robinson mentioned that the Instructional League roster has a note saying Gerrit Cole will only be in instructs for two weeks before heading to the AFL. Biertempfel then corrected himself and noted that there is still one more spot for a Pirates pitcher that hasn't been announced. So in the end it looks like: OF Robbie Grossman IF Brock Holt IF Jarek Cunningham RHP Phil Irwin RHP Michael Colla LHP Nate Baker RHP Gerrit Cole*
