Wait, what
Syndergaard NOT involved, per DiComo:
Gotta be a 3-way trade.
Mets don't have a top 50 prospect.
I can't imagine Mets would trade McNeil or Alonso.
The other bad thought I had is it could be a Baty or Allan as a PTBNL like the one guy the Pirates traded as a PTBNL in the Archer deal (Swaggerty?)
