Ross Detwiler has really improved his mental approach. Much more self-confident.
Tyler Moore has been able to prove himself time and time again that he's ready for the majors.
Bryce Harper matured very quickly and has shown a ton of promise. He reinvigorated this ballclub and it'd be hard to imagine the Nats would have done what they had without his callup.
H-Rod was pitching hurt and not mentally breaking down, he has the chance to prove himself again.
Rodger Bernadina, a freaking bench player, got a great nickname and always gets the crowd moving when he's at bat!
I could do this allll day
