Barnhart remains out of the lineup for Monday's game against the Astros.
Barnhart had already been occupying the smaller side of a timeshare at catcher with Miguel Amaya early last week, but the former has seen his playing-time outlook become worse with the return of Yan Gomes (concussion) from the 7-day injured list. Even with Amaya now back in the minors, Barnhart has now sat out five times in the Cubs' last six games.
