Per Rich Thompson's Twitter:
Sad to see Sean Rodriguez heading to Tampa Bay, good luck to him he is an exciting player
Assuming the account is legitimate, and it seems as such, the Rays will receive the 24-year-old Rodriguez alongside Matthew Sweeney and Alexander Torres. We talked about Rodriguez earlier as the potential PTBNL and his mighty fine looking statline. The scouting reports on him are simple. He's probably not a shortstop, but has a good bat and should work at most defensive positions.
Welcome to the organization Sean.
Update: Per a Rays press release, they have acquired Rodriguez and he will report to Durham. Presumably until the 'second wave' of call-ups.
