NY trades:
Joba
Hughes
Tabata
Cano
Kennedy

Boston:
Ellsbury
Buchholz
Lester
Masterson
Lowrie

Minnesota:
Santana

St. Louis:
Eckstein (knows how to win)

NY is able to shift Jeter to SS and Eckstein can move to SS improving D and offense. Santana is the obvious best player in the deal so Boston and NY agree to alternate starts where he pitches for one team and then the other. When facing each other he will start for the home team but can come on in relief for the visiting team.

btw: the best feature of this trade is all boston and ny rookies are gone and we don't have to listen to all these hughes vs. chicken salad sandwhich offers.
