"He's smiling, which is always a good sign. It's always good when a player is coming off an injury that he's smiling easily. I'm seeing everything trending in the right direction." Willson Contreras, who is also on the disabled list, had an active day Anthony Rizzo Jersey on Wednesday, handling balls Addison Russell Jersey behind the plate from a pitching machine Anthony Rizzo Jersey and also throwing to second base. Contreras, out since Aug. 11 with a right hamstring strain, was expected to be sidelined for a minimum of four weeks, and that timeline has not changed.

It's part of Maddon's plan. "In lieu of traditionally trying to hit balls in the Chicago Cubs Jerseys seats [during batting practice], I prefer doing work like this, especially at this time of the year," Maddon said.
