The Red Sox have designated reliever Edward Mujica for assignment. Mujica had a 4.61 ERA in 13.2 innings over 11 appearances this year. Opponents were hitting .294/.345/.490 against him.
Alex Speier of the Globe notes that the move coincides with Wednesday's decision to move Matt Barnes to Pawtucket's bullpen and "suggests the Sox may be laying the groundwork to add him as a potential swing-and-miss power arm to their late-innings mix".
