St. Louis Cardinals release Ty Wigginton

The Cardinals announced Tuesday that the club has released utility player Ty Wigginton.

The open roster spot was filled by catcher Rob Johnson who was working with the franchise's top pitching prospects in Class AAA Memphis.

Necessitated by the injury to Yadier Molina's knee that left the Cardinals with only one available catcher over the weekend, Johnson gives the big league club some depth while Molina gets back up to speed.
