"my shoulder feels normal and back to 100% - just kept doing the rehab exercises to maintain it." "been working with Derek Shelton since November we are working on refining my swing and staying through the middle of the field." "I couldnt train last offseason cuz of my shoulder surgery- this offseason i tried to gain weight and started hitting earlier."Some twitter quotes from Upton, in response to questions fans asked him. Nice of him to be so forthcoming; he answered around 15 questions in total.
