"Everything feels good," Walden said. "I've got to see how I feel tomorrow."
With Eric O'Flaherty lost for the remainder of the season after undergoing Tommy John elbow reconstruction surgery, Walden could eventually team with Luis Avilan to serve as closer Craig Kimbrel's top setup men.
When Walden completed consecutive scoreless appearances against the Nationals on April 29 and May 2, his ERA stood at 1.54 through his first 11 appearances of the season. But as his shoulder started to bother him, the former Angels closer allowed five runs and totaled 1 1/3 innings in the three appearances that followed.
