Mike Olt said Sunday that the vision issues that plagued him last year are entirely behind him now. Once thought of as one of the top prospects in the game, Olt's stock has tumbled after slashing a brutal .201/.303/.381 with a 132/55 K/BB ratio over 107 minor league contests in 2013. If healthy and seeing the ball better though, it's conceivable he could impress enough this spring to earn a shot at being the Cubs regular third baseman to begin the season.
