The Rangers designated Anderson for assignment Sunday.
He'll cede his spot on the 40-man roster and 26-man active roster to right-hander Gerson Garabito, whose contract was selected from Triple-A Round Rock ahead of his scheduled start Sunday against the Twins. After being called up from Round Rock on May 15, Anderson proceeded to make a pair of relief appearances for the Rangers, giving up two earned runs on six hits and one walk while striking out three over 3.1 innings.
