Need ERA help!! Rank pitchers accordingly..WHIR!!

[BiGAnT]

My ERA is literally above 5 and I just traded Tim Hudson (Chris Young, Hudson and Izturis for Kemp). I need pitching help and I have two open roster spots, 1 which is devoted to pitching and the other may wind up being for pitching too (but right now its for an OF).

Randy Wolf
Dice-K
Jair Jurrjens
Brandon Beachy
Freddy Garcia
Zach Britton
Wade Davis
Bartolo Colon
Dustin Moseley
John Lackey
Kevin Correia

Don't need to go through all of them, just want the top few best and which ones you would grab if you had a 15 add/drop limit but are already at 12!! HAHA I'm very impatient so I add/drop wayy too much. Thanks so much!! Just drop your link and everything will be returned!

1B Ryan howard
2B Brandon Phillips
3B Casey McGehee
