Jackson time in St. Louis?

The St. Louis Cardinals don't have a problem scoring runs or getting good pitching from their current staff. They have one of the best records in all of baseball and appear headed for the postseason once again. Their one offensive weak spot is shortstop, where Pete Kozma is batting .241/.286/.305, and has hit under .200 since the end of May. Daniel Descalso has picked up some time at shortstop as a result of Kozma's struggles, but the club also has an option in Triple-A Memphis.
