Doumit on DL, need a catcher

[roundBallJef]

I have both Mauer and Doumit on the DL, and need to pick up a catcher. I used the empty roster spot that Doumit gave me to pick up Alexei Ramirez from waivers. I need to drop someone to pick up a catcher. FA catchers are:

Posada
Pierzynski
Suzuki
Shoppach
Flores
Hundley

My team is:
Albert Pujols
Aramis Ramírez
Derrek Lee
Alexei Ramirez
J.J. Hardy
Khalil Greene
Aaron Hill
Rickie Weeks
Álex Ríos
Grady Sizemore
Adam Lind
Matt Kemp
Carlos Peña
B.J. Upton
Hank Blalock
Ian Stewart
Justin Upton
Billy Butler

DL Ryan Doumit
DL Joe Mauer


Johan Santana
CC Sabathia
James Shields
John Danks
Matt Cain
Rich Harden
Johnny Cueto
Tommy Hanson
Mariano Rivera
Brian Fuentes
Heath Bell

It's a keeper league, so I won't drop Justin Upton. So, who should I pick up, and who should I drop?
Thanks, WHIR

Drop Billy Butler and get Posada. Butler will still be there if you want him when Mauer comes off the DL in two weeks. if you'd rather drop a SP, drop Cueto.

Thansk for your help.
