The Indians have released reliever Scott Atchison, the club announced. The 39-year-old righty had been designated for assignment earlier in the week.

Atchison struggled to a 6.86 ERA over 19 2/3 innings this season, though ERA estimators such as xFIP (4.35) and SIERA (4.03) paint a somewhat more sympathetic view of his 2015 performance. Atchison has been badly hurt by the long ball, as he’s already allowed six homers and owns a 2.75 HR/9, which more than triples his 0.91 career HR/9. His 42% ground ball rate is also well below his career 49.7% GBR, which especially hurts since Atchison isn’t a strikeout pitcher.

Cleveland signed Atchison to a $1MM extension last August that paid him a $900K base salary in 2015 as well as a $100K buyout of a $1MM option for 2016. The right-hander was in the midst of a very solid 2.75 ERA campaign for the Tribe in 2014 and had posted very effective numbers from 2011-14 as a member of the Indians, Mets and Red Sox.

With Atchison’s release, only four players remain in limbo according to the MLB Trade Rumors DFA Tracker: Erik Kratz (Red Sox), Rafael Lopez (Cubs), Jose Tabata (Pirates) and Chris Volstad (Pirates).
