Royals AGM JJ Picollo says here that KC and the Red Sox made a 2-team deal involving Benintendi and Khalil Lee and then Red Sox informed KC they were flipping Lee to the Mets. Red Sox were the middle man; KC and NYM didn't talk directly.
If this is the case, the PTBNL from NYM should be substantial. Otherwise, it's a deal of Lee for Winckowski and something underwhelming. At that point, wouldn't you just keep Lee?
