Bye Bye L-Rod
The biggest beneficiary of this move is probably Tommy Watkins, who with his consistent play has likely earned a place on the team for the rest of the season, even after Brian Buscher returns. Had the Twins decided to keep Rodriguez up, I'm guessing Watkins would have been sent down for a week until rosters expanded in September. Rodriguez will probably return in September (there'd be no reason not to call him up again), but this way the option was used on Rodriguez -- a player who isn't that useful for the Twins long-term -- rather than on Watkins, who at least might be useful.
This move comes about four months too late, but I'll take it nonetheless.
