Really quick, here are some moves to fix the lineup and defense:
-Sign Infante (plus defender and not bad with the bat at all)
-Sign Baker (platoons with Gose in LF and provides depth at 1B and 3B too)
-Sign Clint Barmes (metrics say he is every bit as good as Brendan Ryan and he's better with the bat)
-Trade Loup for Martin Maldonado (subpar bat but plus defender and excellent pitch framer, he's also not older than dirt like Molina)
-Pick up Lind's option, throw in 2 million (he costs that much to buyout anyway), and trade him for the best prospect we can get
-Dump one of Maicer or DeRosa (can't afford to waste two bench spots, Izturis would require eating salary)
LINEUP
1. SS Reyes (S)
2. RF Bautista
3. CF Rasmus (L)
4. 1B Encarnacion
5. 3B Lawrie
6. DH Melky (S)
7. 2B Infante
8. C Maldonado
9. LF Gose/Baker (L/R) *move Baker up against lefties
BENCH
C-Thole (L)
UT-Baker
SS-Barmes
UT-Pick your poison, DeRosa or Izturis (S)
The defense takes a big step forward here as Infante, Maldonado, and Gose are given everyday roles over the rotating junk at 2B, JPA, and Melky. Barmes is a huge upgrade off the bench over the likes of Maicer, Kawasaki, Boni, etc. It's not all defensive additions, however, as Infante can hit and Baker can hit LHP.
I'll get to the rotation/bullpen later but the rotation will be better even if no moves are made (although I fully expect some to be made).
