I would turn that Giolito "club option" into a player option. I would guess he's looking at a deal similar to Rodon (1 year, 1 year player option) to leave for a better deal if he pitches great after 1 season.
Thinking about this more, I feel like they didn’t want to gamble on both TA and Moncada being productive players and took the opportunity to get out of some potential bad money. Still hoping Moncada gets moved though.
You could sign him to a 2 year deal where he gets very little year 1, and then $8M in year 2. And if I could bet on it, I would bet the Sox come to some sort of agreement like that.
