From what I can see, the new strike zone and new catcher both help Santiago. He works up in the zone (so did Phil Hughes during his fine 2014) and has a lot of balls hit in the air. The good defensive outfield the Twins can put out there helps greatly, so does the weather if the fly balls aren't carrying that much. It is an oversimplification to say pitches at the top of the zone are mistakes, particularly fastballs. Last night, Bert criticized every well-hit ball by the Tribe with "he got that one up", more accurately the pitches were up in the zone and over the heart of the plate. Movement can allow a high strike over the middle to be a good pitch, too.
