whoops. The number is accurate, but you’re correct that I inverted K/BB. Fixed now, thanks.

This has to do with his mechanics. When a hitter gets a rib/back injury the first thing that happens is reduced bat speed. Trumbo began compensating for this by opening his hips up earlier and committing to swinging earlier. The byproduct of this is committing to swinging before you can recognize the pitch isn’t a fastball and the end result is a lot of ugly swings at offspeed pitches (more Ks, fewer BBs). If he’s healthy and can get his mechanics right again, I think he can sit at a .280+/.340/.560 year with lots of RBI chances.
My observation of Trumbo after the ASG HR competition was that he appeared uncertain and unable to pull the trigger on pitches that were in his hitting zone. I had never bought into the ASG HR competition significantly altering a participants mechanics, but the competition seemed to have effected his psychological approach. So many times his muscle-memory would start the swing, but then his brain would hit abort.
