Rafael Furcal will miss the 2013 season because of Tommy John surgery, leaving the Cardinals with a hole at shortstop.

Pete Kozma and Ryan Jackson shared shortstop duties at Triple-A Memphis last year, but Jackson actually played more than twice as many games at the position (102 to 45).

Numbers indicate that Jackson is the superior fielder, as he made 4.18 plays per game at Memphis to Kozma's 3.02. Jackson had a better fielding percentage and turned a higher percentage of double plays. He even hit better -- .272/.334/.396 versus Kozma's .232/.292/.355.

However, Kozma got the call when Furcal was injured last September and hit surprisingly well (.333/.383/.569).
