So, I'm not sure how much credit we should give Chili but I was looking at late night stats as I'm prone to do and it occurs to me just how significant the cubs K rate issues have disappeared save for Happ and Schwarber to a lessor extent. Here's what i'm talking about
2018 numbers / 2017
Bryant - 13.5 % / 19.2 %
Baez - 22.0 % / 28.3 %
Zobrist - 10.2 % / 14.3 %
Almora - 15.6 % / 16.4 %
Russell - 15.0 % / 23.6 %
Contreras - 20.6 % / 22.9 %
Schwarber - 31.5 % / 30.9 %
Happ - 47.2 % / 31.2 %
Caratini - 23.3 % / 19.7 %
La Stella - 18.2 % / 11.9 %
Heyward - 12.1 % / 13.9 %
Rizzo - 18.9 % / 13.0 %
Also as a reference point on the year the MLB average for non pitchers is 22.4 %. The only players the cubs have over that at the moment are Happ, Caratini and Schwarber and Caratini is likely just lack of playing time. Last year that same mark was 21.2% and the list was Baez, Russell, Contreras, Schwarber, and Happ all over.
