advancements implies that he was bad at it before(I don't think that's the case), but yes, Russell was very good on high fastballs last year, especially in the second half Yeah that's what I'm talking about. He was pretty bad in the first half and then after some tweaks he really turned a corner and was way better in the 2nd handling those pitches. Whatever developments that occurred look to have not stuck. Pitchers are relentlessly attacking him there. Sent from my SM-N900T using Tapatalk
