When I wrote my comment Young K 9 times in 45 AB’s. Isn’t that 20%?
I think more often you use plate appearances so you have a more consistent baseline between walk and k rates. After today, he has an 8.9 BB% and 16.1 K%. That's equal to the 25th best qualified hitter (Yandy Diaz) out of 138. 18th%. Small sample, but a good sign. And the BB% is better than MLB average too (8.6%).
