The Orioles designated Vavra for assignment Wednesday.
Vavra was added back to the Orioles' 40-man roster in late July, but he was optioned back to Triple-A Norfolk a day later once Baltimore's trade-deadline acquisitions joined up with the club. The 27-year-old will now move back off the 40-man roster as the Orioles clear room for infielder Emmanuel Rivera, who was claimed off waivers from the Marlins. Vavra will now be subject to the waiver process, but if he clears, he would have the ability to elect free agency since he was previously outrighted off the 40-man roster last November. He's produced a .243/.350/.368 slash line with three home runs and two stolen bases over 178 plate appearances at Norfolk this season.
