Baseball America has now updated signing bonuses for all 17 of the Phils' signed draftees. I've updated the table in the top post.
Note that for several players, there are minor discrepancies between the bonuses reported by BA (Chris Collazo) and MLB (Jim Callis or Jonathan Mayo). For consistency, where one of the reported bonuses excluded the $2,500 accounting gimmick, and the other did not, I've opted to show the lower bonus amount (because most of the undisputed bonuses have pretty obviously excluded this $2,500). But there's no guarantee that this is correct.
Still not a lot of information on bonuses paid to UDFA, but it looks like they haven't exceeded $125k on any of them.
About $50k available to sweeten a contract for Braylen Wimmer.
