Jason Heyward?

I'm new here and I don't fully understand how to post and create fanshots and all so please be patient with me please.I'm a huge Braves fan and I try to keep up with their minor league teams as well as with the Braves.I was looking at some rosters and I seen Jason Heyward on the Danville roster and I haven't seen any reason for him being there.I don't know if he's injuried and is on an injury rehab run or what,I seen his stats at Myrtle Beach and he seemed to be doing just fine.I haven't seen or heard anything about him having a bad attitude or something like that to cause him to be demoted.I got to wondering about this topic.I know that there are fans out there who has access to more info about this team and its players than I do so if anyone out there can help i would greatly apprieciate it,also please give me some tips about this site ,you know how to post and create fanshots and pictures and all you know stuff like that.
