I have not seen the Baltimore games, so I can't comment on those gaffes. I was thrilled with his defense prior, especially with his turns on double plays which are smooth. I figured his arm could make up for that but it hasn't needed to.
Overall, I feel super confident he'll put in a tough at bat and see pitches.
Considering how cheap he was in talent and cost, I feel great about him. Nice to have one position removed from the "needs upgrade" status
