The Cardinals converted Kelly to a catcher a year ago and he's taking nicely to the position. He's a natural receiver, looks comfortable behind the plate and throws well. He won't require more time than usual to develop at the position and should be able to handle it at the major league level. He won't be an elite defender, but he'll be good enough defensively to handle a pitching staff on a daily basis.

At the plate, his bat lags behind his glove, and behind fastballs with any velocity. Below average bat speed really hinders Kelly as a hitter and leads to a lot of bad contact. His natural size and strength will lead to a little bit of power, but he'll be a mistake hitter at the higher levels.

The offensive bar is low for catchers, but Kelly projects to end up in more of a back-up role. His background playing the infield could lead to a utility/bench role with the versatility to play a few different positions, including catcher, making him a potentially valuable bench piece.
