I don’t have a definitive answer to that, but Michael Arace of my hometown Columbus Dispatch says that it’s Mike Sarbaugh, manager of the Indians AAA team, the Columbus Clippers:
In eight seasons since Sarbaugh started managing, his teams have made the playoffs every year save one … Sarbaugh has won championships in the New York-Penn, Carolina, Eastern and International leagues … It is almost as if you can give Sarbaugh nine lawn chairs and they will contend.
Obviously winning in the minor leagues is a different deal than it is in the majors. Especially at AAA, where the team can be used as either a talent repository or a holding cell for AAAA players or both, depending on the whim of the organization. But you gotta measure it somehow, and winning is not a bad starting point. Columbus has a 13-game lead in their division.
The only thing giving me pause: the last time a Clippers manager was touted as the next big major league managing prospect it was … Trey Hillman.
But at the very least you can get to know Mr. Sarbaugh if you aren’t already acquainted.
