Two mistakes on your part, One mistake on mine.
1) Tom Pyatt is listed twice on my roster. This should put me at 100k of cap left.
2) Brian Flynn is listed as both in my minors and as an IR relief for Erskine. Keeping him on as an IR relief will keep me at exactly 20 players for my minor roster cap.
3) So I seem to have forgotten a player in my paperwork and I am over the minor cap by 1.2M. To fix this, I am going to release Chris Philips from his IR contract and call up Steve Oleksy as his IR replacement. I should have 300k of cap left in my minor league roster.
