I know most of you didn't care for Apple TV+ announcers, BUT one of the announcers acknowledged Lopez's higher walk rate since being traded. He/she (I can't remember which announcer, I was at work) stated that Baltimore catchers are taught to set up over the middle of the plate instead of on the edges and maybe that was the reason. It makes a bit of sense in that if you are aiming for the glove, and it is over the middle of the plate, if you miss to either side, you will probably still be over the plate. And as we have seen with MLB players continuing to hit into the shift, learned behaviors at this level are hard to break (in this case both pitcher and catcher).
