Barnhart will no longer be a switch hitter and will instead hit exclusively from the left side of the plate, C. Trent Rosecrans of The Athletic reports.
Over the last three years, Barnhart has a .651 OPS against left-handers, but that dropped to .390 (.133/.235/.156 in 51 plate appearances) last year. With lefty-mashing Curt Casali as his backup, it's most likely that Barnhart will have limited exposure to lefties with this change.
