The Orioles announced that they released right-handed reliever Kevin Gregg (Twitter link). They had designated Gregg for assignment earlier in the week to create space on the 40-man roster.

Gregg signed a two-year, $10MM contract with Baltimore after the 2010 season, but he struggled with the Orioles, posting a 4.53 ERA from 2011-12. He appeared in 40 games this year, posting a 4.74 ERA with 7.6 K/9, 4.9 BB/9 and a 47.8 % ground ball rate in 43 2/3 innings. The 34-year-old's contract included a $6MM team option for 2013 that evidently won't be exercised.
