Out of fairness to chatwood, I don't see how Bettis is going to be materially better.  last year (Bettis' break out year) he was 4.79 ERA, 101 ERA+ and 1.414 WHIP vs Chatwood ytd: 4.78, 105 & 1.463.  So it looks like we are replacing chatwood with the same guy....the only real difference is Bettis pitches to contact and gives up more hits and chatwood pitches to the screen...
