The Orioles designated Garcia for assignment Sunday, Nathan Ruiz of The Baltimore Sun reports.
Garcia will cede his spot on the 40-man roster to catcher Cam Gallagher, whom the Orioles claimed off waivers from the Padres. Over his eight innings with the Orioles this season before he was optioned to Triple-A Norfolk earlier this month, Garcia allowed four earned runs on eight hits and three walks while striking out two batters.
