Relievers available

[Cardinals]

After a few deals, my pen is looking pretty nice, but there's too many cooks in the kitchen as far as righties go. Rivera, Frieri and Hoover are staying put, but I don't need all of the rest of these guys:

Broxton: 3.59 ERA, .240/.312/.383 against, 8.7 k/9, 61% GB
Boxberger: 3.48 ERA, .215/.331/.339 against, 11 K/9, 54% GB
Villareal: 3.53 ERA, .211/.316/.332 against, 10.85 k/9, 36% GB
Brach: 3.61 ERA, .231/.304/.372 against, 9.46 k/9, 41% GB
Freddy Garcia: 3.91 ERA, .251/.308/.385 against, 6.47 k/9, 46% GB -- Av start and relief durability

I'm looking for bench upgrades, prospects and picks. I still need a pretty good RH bat off the bench.

edit: those are sim numbers for '13.
