Stunner: Michigan pitching coach Bob Keller just called me & said, "I've been released from Michigan baseball." He'll land new job quickly.
Pretty shocking given all the talent he has produced the last few years. No idea what this might mean for any current players. I know Ballantine came to Michigan to come under the same pitching instruction that similarly built Chris Fetter was built up in.
At the same time, the regression of the bullpen over the course of the last two seasons has been somewhat suspect. I'll bring more details in as I get them.
Keller had been an assistant at Michigan since 2005. MGoBlue Bio.
