Mullins is not in the Rays' starting lineup against the Mariners on Friday, Marc Topkin of the Tampa Bay Times reports.
Even though the Mariners are sending right-hander Logan Gilbert to the mound, the lefty-hitting Mullins will open Friday's game on the bench while Jonny DeLuca starts in center field and bats sixth. Mullins has gone 12-for-53 (.226) with three steals (in four attempts), two home runs, five RBI and 10 runs scored since the All-Star break.
