Cardinals reliever will miss the remainder of the 2015 season, Derrick Goold of the St. Louis Post-Dispatch reports. GM John Mozeliak said that the right-hander will have to endure a rigorous rehab to return to the mound if he chooses not to undergo surgery.
Walden, 27, has been out since late April due to a biceps injury he recently admitted is related to damage in his rotator cuff and labrum. He had posted a 0.87 ERA with a 12/4 K/BB ratio in 10 1/3 innings prior to the injury.
The Cardinals acquired Walden from the Braves along with outfielder Jason Heyward in last November’s trade which sent starter Shelby Miller and minor leaguer Tyrell Jenkins to Atlanta.
