Here are the pitchers rumored to be on our radar.
Kuroda - 127 IP, 3.19 ERA, 1.22 WHIP, 3.77 FIP
Jiminez - 122 IP, 4.20 ERA, 1.34 WHIP, 3.48 FIP
Bedard - 90 IP, 3.00 ERA, 1.11 WHIP, 3.59 FIP
Harden - 23.1 IP, 4.63 ERA, 1.24 WHIP, 4.83 FIP (ineffective in 2010)
I think Bedard would be the best fit of cost vs. need even though he's kind of a dick and struggles to stay healthy.
