Chatwood's arm is awesome, he seems like a good guy, & it's REALLY easy for me to pull for an MLB pitcher who's 6 foot even, & has been thru 2 Tommy John surgeries.
And I'm usually OVERLY hesitant about moving on from a player, but this game did it. Obviously, he might come out in his next appearance & throw a no hitter. But he just CAN'T be counted on to play a pivotal role on a team that's going all in on a RARE playoff push(& plays half their games at Coors Field).
I have NEVER seen a pitcher who SO often will be cruising along & COMPLETELY dominating a game thru 3, 4, 5, or 6 innings, & literally ONE thing goes wrong... a bad call, an error, a bloop hit, or a bad bounce, & he COMPLETELY falls apart. 
And once the wheels start coming off he just doesn't have the mental where with all to get things back on track.
As much as it sucks to say, if he hasn't been able to overcome this by the age of 27, I'm finally sapped out of hope that he will, & think it's time the Rockies cut bait.
