I was confused because he mentioned miller
I think he meant Warren
why should GTR not be happy with castro? for 9.5M a year, they got a guy who has an OBP <300
thats about the going rate these days
He can hit close to .300 (with his OBP being just a few ticks higher) with around 15 homers, and has range in the field. The problem is that he does that every second year, and that it comes along with many errors and base running mistakes.
My take on it is that it seems that the Yankees won this trade and most experts would say that. However, in two years (assuming Castro has one good year and one bad one) they can all point out how a 3 and change ERA in the AL east translates to an ERA under 3 in the NL. Also, it is almost certain that Zobrist's OBP will be higher than Castro's.
