I believe people are suggesting Rich Hill has been better than Z since the middle of last season. There are causes for concern for Z though - his back, his weight, his BBs. Since August 1: Rich Hill: 83.2 IP, 2.47 ERA, 84 K/21 BB, 0.91 WHIP, 11 HR Carlos Zambrano: 78 IP, 4.62 ERA, 68 K/44 BB, 1.47 WHIP, 8 HR Carlos has better stuff and has a much longer and better history but Hill obviously has been much, much better over the last half season. 4:1 strikeout ratios are great. 3:2 not so much.
