Here's some other ones to look into. In general, you want to look at marginal pitchers on teams that have high run support:
Wade Miller (jump all over him if you can get him cheap)
Jose Contreras (currently on DL)
Casey Fossum (currently on DL)
Mark Hendrikson (gets a ridiculous 8 runs per game of support)
Look at Seo. His last 4 starts against the Braves(twice), Seattle
and Texas. 29 ip, 25 hits, 6 earned runs, 6 walks, 12 ks and
3 wins. His ks are low but pitching for the Mets and their sorry
defense, I think he is a keeper. I like Franklin also, I have them
both. K Wood takes care of my Ks
I'd like to second Seo. He was once a top prospect in the Mets organization and he the infamous Tommy John surgery. He seems pretty solid, although he's on the Mets. He used to throw in the mid-90's and now he PITCHES in the high-80's to low-90's. So far, though, I've gotten some pretty good numbers out of him. He seems to be one of those guys that can eat innings and not hurt you too badly on bad days. He won't have the monster game, but he won't have the 8 walk game either.
Plus, he bows to the umps every time they throw him the ball. I think that's cool.
Oh yeah, another good option is to sign any pitcher that's going up against the Rangers. Their lineup looks imposing, but they have a horrible average with guys in scoring position. I, for one, am going to sign and release any halfway decent option going against the Rangers as my 7th pitching position.
