I'd like to see the K rate a little lower too, but for it to go down without sacrificing BB would put him at a 1:1 K/BB, and I don't think he has to be at that level for me to consider him beating expectations. Plus if he's making better swing decisions we'll expect the Ks to marginally increase along with the BBs as a function of more deep counts. But zoom out a small bit and he's putting up cartoon results while demonstrating progress in the 2 big questions people have(swing decisions and IF defense). Maybe AAA is the level where things get harder but it seems very fair to me to be pretty excited as things stand today.
