Red Sox release ex-Cub Mark Prior

NEW YORK -- Mark Prior's bid to return to the major leagues with the Red Sox has come to an end.

The former Chicago Cubs star was given his release by Triple-A Pawtucket to make room for Pedro Beato, the right-handed pitcher the Sox acquired from the New York Mets in the Kelly Shoppach deal.

Prior, 31, made 19 appearances for the PawSox this season, going 1-0 with a 3.96 ERA. But he walked 23 batters in 25 innings, compared to 38 strikeouts.
