Throwing from a slightly lower arm slot, with a slightly more exaggerated elbow angle, is not per se an indicator of injury, and normally it could be attributed to a minor mechanical blip, the likes of which fellow Yankee—and new closer—Dellin Betances experienced earlier this summer. But combined with Chapman’s recent injury history, it represents a more serious sign of concern. In the book Complete Conditioning for Baseball, collegiate strength and conditioning coach Steve Tamborra writes, “There is no ideal angle between the arm and the head during the throwing motion, but pitchers tend to lower their angle when protecting a weak or injured shoulder.”
This is still just an observation, and it’s impossible to link it explicitly to Chapman’s struggles—again, his aggregate velocity and location are doing just fine, and both Chapman and Girardi contend that the lefty isn’t hurt. But it’s a new Chapman, and it’s a worse Chapman, so it’s reasonable to suppose that some connection exists.
If it’s an injury, we can count on the Yankees’ crack medical staff to get to the bottom of it.
Whatever it is, the Chapman contract is already looking like a dud. Not as bad as the Smellsbury contract, but a dud.
I miss Mariano Rivera terribly.
