Keith is out of the lineup for Monday's game against the Mets, Evan Woodbery of MLive.com reports.
After starting in each of the Tigers' last six games, the left-handed-hitting Keith will retreat to the bench while the Mets send southpaw Sean Manaea to the hill for the series opener. Keith is slashing just .143/.200/.167 over 45 plate appearances versus lefties this season.
