Baltimore Orioles outfielder/designated hitter Mark Trumbo is not in Friday's lineup due to back spasms.
The Orioles expect him to be able to play Saturday. Michael Bourn is replacing Trumbo in right field on Friday against the Tampa Bay Rays.
Trumbo is posting career-bests with a .350 wOBA and .271 ISO this season, while also recording a .248/.311/.519 across 608 plate appearances.
