I think it's fair to say though that he's been an average player his rookie year, all things considered. And that's pretty impressive for a guy who has a negligible amount of minor league experience, in his rookie year, and first year playing in a new organization.
With that being said... I saw on MLB network today that Tuck has an OPS of .901 against lefties this year. That's pretty wild. Not sure what more this guy needs to do to get 500 mill from the Cubs
