Here’s Brian Cashman commenting on the trade:
Swisher is not here to play CF. Cashman made that clear. He’s here to play 1B. Cashman did not close the door to anything else happening (he never does), but it’s pretty evident that they see Swisher playing 1B and having the ability to play LF or RF on occasion. That would enable them to keep Jorge Posada in the lineup once in a while as the 1B.
Jeff Marquez was on the 40-man roster while Jhonny Nunez would have required Rule 5 protection. Kanekoa Texeira does not require such protection. The side benefit to this move is roster flexibility.
There is no “losing” Wilson Betemit. There is dumping Wilson Betemit.
The White Sox save money on this deal, that’s their upside. Swisher never quite fit there for assorted reasons, mainly Ozzie Guillen using him at the top of the order. Marquez could turn into something. Nunez was a guy they got for Alberto Gonzalez in July. No big loss.
This move allows the Yankees to focus their attention (and money) on starting pitching. Mark Teixeira just lost a lot of leverage.
