Wilkerson was outrighted off the 40-man roster last month and will now test the open market. The 29-year-old holds a .210/.268/.340 batting line over 486 plate appearances in the majors. 

Wilkerson went unclaimed after being designated for assignment by the Orioles on Wednesday. The outfielder has hit just .167 over 72 at-bats this year, and will try and pick things up in Triple-A Norfolk. Baltimore will have to add him to the 40-man roster if they want him back on the MLB team, however. 

The Orioles needed to create a spot on the roster for right-hander Spenser Watkins after making several roster transactions on Wednesday. Wilkerson is likely to clear waivers and end up back in the Orioles organization. 

The 29-year-old struggled in the majors this season, batting .167/.211/.208 over 72 at-bats with two RBI and five runs scored. Wilkerson will head back to Triple-A where he was off to a great start batting .357 over 42 at-bats.
