Yankees closer Aroldis Chapman is a powerhouse when he’s “on,” but more importantly, he’s a pent-up ball of fury and a creature of habit — something Aaron Boone still doesn’t seem to realize after nearly four years of trying to facilitate his success.
Whether it’s a bum fingernail, a decided lack of stickiness, or something else entirely, Chapman has been off more often than he’s been on lately, throwing up all sorts of regression on the mound that has turned his fantastic start into a distant memory.
