I agree that Chourio defense has been very good this year. His all around game has improved as well, but at the same time you could say he's been remarkable consistent his first three years in the majors. That's impressive for a guy coming up as a teenager. He has hit exactly 21 HRs each year (hopefully he will have a few more this year). His wRC+ is 119, 112, and 122. His OPS is 791, 770, and 810. Again, he is better this year than previously but its incremental. He did already start at a pretty high level to begin his career, so it wont take too much to achieve superstar level. He is moving in the right direction for sure.
