Relative to the rest of this anemic offense, he is a "good hitter" right now. In July, his SLG is over .700 and his K rate is around 32%, which is still high, but perfectly acceptable when he's driving the ball and getting on base.
Poor timing to send him down. I understand the move from a roster construction standpoint based on the need for another bullpen arm and lack of healthy CF options, but really the issue is that we're carrying 3 catchers. Hopefully Severino gets dealt soon.
