That is freaking awesome. 2013 opening day lineup should have Harper and Rendon in it!
I don't get the fuss about the shoulder. He's a position player! Granted I'm not a pro baseball player but I tore my labrum and although I lost velo, I still had a good arm. Maybe Rendon doesn't have the arm for 3rd anymore but he'll easily have it for 2b or LF. No matter how bad it is.
We just got the steal of the draft.
