SP Craig Italiano is pwning the Midwest league. 7 - 0, 0.74 ERA, 61 innings, only 35 hits, 5 earned runs, 1 homer, 28 walks, 71 k's, and a 1.03 WHIP
1B Sean Doolittle is hitting .323 with 15 homers and 46 RBIs. He's got a 1.027 OPS
I believe SP James Simmons has been shut down for a little while with "dead arm"...he's not injured, they're just letting him rest and limiting his innings.
SP Vince Mazzaro is doing quite well in AA. 6 - 2 with a 2.44 ERA in 66.1 innings. He's got 18 walks and 45 k's.
As far as I can tell they're leaving SP H-Rod in AA despite his ERA being over 8 and his control being off. Beane basically said that since he's striking out >1 batter / inning, that he'll be up there because that is a good indicator that he will have success up there. They expect the other numbers to improve with time. I think it also has to do with the fact that there isn't really a rotation spot for him back in Stockton with Anderson, Cahill, Lansford, etc...and they don't want to send him to Kane County.
SP Gio Gonzalez isn't doing that great at AAA. His ERA is almost 6. I wouldn't expect him to get called up this year with those kind of results.
