In thinking about our options relative to improving our SP and the DH spot, one could make a case that we are better off trading Aybar for pitching and signing Stephen Drew.
Here is the math:
Drew is probably equivalent to or perhaps provides slightly more value than Aybar. He's a very good defender with good pop who has a solid obp. He'll be just 31 to start the season Aybar will be 30.
It appears that Drew is going to get 3/40 or maybe 4/50.
Let's say Garza will cost you 4/70 or 5/80.
Obviously, it depends what you can get for Aybar, but it would make sesne that you could get a player similar to what Garza is going to be over the next 4-5 years yet younger and cheaper with potentially more upside.
12.5mil for Drew minus 8.5 from trading Aybar plus league min for who Aybar gets you in return adds about 4.5 mil in payroll. Probably a shade more than what Ibanez is going to cost.
Leaving you about 15mil to add a hitter or even another pitcher to further improve SP depth.
To clear more space, you could also move Ianetta for some minor league depth or a pen arm although this would weaken the offense a bit. But that would give you 20mil to spend.
That could bring Choo into the mix or you could then trade Howie for a decent DH, Pitching prospect etc.
The one downside of signing Drew is that he's tied to a pick which the halos have indicated they would avoid, but I have to think that with what Aybar can bring you in trade is probably a bit better for the long term health of the team than signing Garza.
