One of the St. Louis Cardinals' goals coming into the offseason was to add a closer. So far, they still haven't done that. They added Luke Gregerson, who does have some closing experience and could potentially fill that role but the back end of the bullpen is still a mess.
Cardinals Prospect Harrison Bader had a tremendous spring for the Cardinals. He slashed 346/404/538/942 with 5 extra base hits in 52 AB. Bader was one of the last cuts from camp, and he definitely impressed the parent club during his turn with the team this spring. Spring success is a weird thing, though.
