Walden may get the first shot at closing for the Cardinals should Trevor Rosenthal be taken out of the role for some reason, the St. Louis Post-Dispatch reports. Matheny has suggested that Walden could be used in the ninth inning, a good indication that with a strong spring Walden will likely be the top setup man for the Cardinals, racking up holds and the occasional save this season. Walden sports a career 3.10 ERA and 10.8 K/9. He could be one of the more valuable non-closing relievers in 2015.
