Some of Aroldis Chapman's teammates with the Cincinnati Reds found him to be entirely mysterious, someone they really didn't know anything about except for those 8-10 minutes he climbed the mound two or three times a week. The tall left-hander mostly kept to himself in the clubhouse and when the team traveled, before he was summoned out of the bullpen to throw 100 mph fastballs.
Then, after the high-fives and shared smiles, Chapman would retreat back into his cone of privacy, which is why, after more than five years playing for Cincinnati, some of his co-workers feel like they have no idea who Chapman really is.
