The Red Sox have released right-hander Mark Prior, according to Brendan McGair of the Pawtucket Times (via Twitter). The move was made in order to create space for the newly-acquired Pedro Beato.

Prior, 31, hooked on with the Red Sox in early May as he looked to attempt yet another comeback. During his time in Triple-A Pawtucket, Prior posted a 3.96 ERA with 13.7 K/9 and 8.3 BB/9 in a small sample size of 25 innings of work. The second-overall pick in 2001 was brilliant in the early portion of his career but has not pitched in the majors since 2006 thanks to a series of shoulder problems.
