Pivetta is struggling, wouldn't surprise me if he was sent down (does he have options left?) and De Los Santos promoted.
It's something mechanical I think, his command of both the FB and curve are off, but also the FB lacks the movement he had earlier in the year, a straight FB over the plate between the knees and waist screams "hit me" even if it's 95 MPH.
Kingery might be finally getting it together.
Looking like Santana was the better FA acquisition, since his slow start has been the steadiest player in the lineup.
