You nailed it.
AT some point he just didn't care. He was getting squeezed and his out pitches were getting hammered, he like had a eff it mentality and just threw.
Last night he got frustrated a few times but you can see a grin come up after he meditated for a few seconds and then brought it. The walk was because he sat so long and he didn't had the feel and when his adrenaline came back on line, lights out. You don't throw near 100 miles an hour the last inning and I believe him when he said he could go another inning.
Maybe his figuring out, he put away two dangerous teams like it was nothing. He need to do this all the time and maybe be 75% of Smoltz who I think was similar.
