The A's designated Hassan for assignment on Wednesday after signing veteran Cody Ross to a one-year contract. Hassan made three appearances for the Boston Red Sox in 2014, before being claimed by the A's, Baltimore Orioles, A's again, and now the Rangers.
Hassan, a right-handed hitter, batted .287/.378/.426 with eight homers and 55 RBIs last year in 114 Triple-A games with the Boston organization. The Rangers currently have five outfielders on their active roster -- Shin-Soo Choo, Leonys Martin, Ryan Rua, Jake Smolinski and Rule 5 draftee Delino DeShields.
