All I kept hearing during the offseason was how Viciedo was supposed to be the worst defensive outfielder in all of baseball. He still has some improving to do with getting good reads off the ball as well as taking better routes to the ball, but he made most of the plays that he was supposed to and he also prevented a fair share of runs, since third base coaches got the memo that Viciedo can throw guys out at the plate.
He has the ability to be a 30 home run hitter. He still has to understand pitchers setting him up but showed the ability to drive the ball the other way and hit the ball hard. I also think its absurd to say that Viciedo hasn't improved one bit.
