Orioles lineup vs. Blue Jays (with Fan Appreciation Weekend details)

Adam Jones is out of the Orioles lineup tonight for the seventh time in the last eight games due to tightness in his back.

Gerardo Parra is leading off and playing center field. Ryan Flaherty is in right, Matt Wieters is the designated hitter and Steve Clevenger is catching.

Wieters is 6-for-15 in his last four games.

Reliever Brad Brach suffered his first loss last night since June 6, snapping a 38-game streak. Darren O'Day hadn't allowed a run in 12 games over 11 1/3 innings before being charged with one last night.

The grounds crew is gathered behind the tarp as more dark clouds roll in at Camden Yards. They already removed the batting cage.
