The one defensive issue I have seen so far is that he occasionally has lapses in concentration in non-big moments and lets more pitches get by him than he should. On the flip side, though, he made a game-saving block earlier this week against Toronto (bases loaded, 7-6 in the 9th) which was very impressive:It is absolutely amazing that until very recently a large part of the baseball world didn't think he'd ever be able to handle the position at the major league level. That arm is just insane
