Orioles' Zac Lowther: Loses 40-man spot

The Orioles designated Lowther for assignment Wednesday, Roch Kubatko of MASNSports.com reports.

The transaction frees up a spot on the 40-man roster for infielder Jonathan Arauz, whom the Orioles claimed off waivers from the Red Sox on Wednesday. Lowther was optioned to Norfolk on June 1, one day after he gave up six runs (five earned) across 5.1 innings of long relief in his lone appearance of the season with the big club.
