"They continue and try and add different mobility exercises, resistance exercises, movement -- the degree of running he's doing right now, I think it's the minimum," Hurdle said Friday. "[McCutchen is] progressing in a positive fashion as of now."
In addition to McCutchen's injury, second baseman Neil Walker was out of the starting lineup for the fifth time in six games Friday due to tightness in his back. Walker was able to take ground balls and batting practice on the field with his teammates -- an improvement from Thursday -- but Hurdle said he's still only available in an emergency scenario Friday.
