According to the Twitter feed of Buster Olney, "teams are being aggressive in pursuit of Randy Wolf, who is one of the best of FA starters not named Lackey."
Wolf threw 214 1/3 innings with a 3.23 ERA in 2009, though it is worth noting that it was his first 200+ inning season since 2003.
For comparison, John Lackey, who is the very best free agent starter who is named Lackey, pitched 176 1/3 innings at a 3.83 ERA. Wolf is 33, Lackey is 31.
