Narvaez is out of the lineup for Sunday's game against the Rays, Matt Weyrich of The Baltimore Sun reports.
Narvaez started five of the previous six games, but he went 0-for-12 with a walk during that span to bring his season-long slash line down to .165/.241/.236 over 242 plate appearances. The Orioles will likely have Samuel Basallo split time between catcher and designated hitter down the stretch, so Narvaez is headed for a reduction in playing time after initially being the top option behind the plate following the Adley Rutschman trade.
