Mesa is not in the Rays' starting lineup against the Astros on Friday, Marc Topkin of the Tampa Bay Times reports.
Even with right-hander Spencer Arrighetti on the mound for the Astros, the lefty-hitting Mesa will be on the bench for Friday's series opener while Jonny DeLuca, Cedric Mullins and Chandler Simpson start in the outfield from left to right. Mesa is slashing .188/.282/.333 with one steal, three home runs and eight RBI across 79 plate appearances this season.
