The Twins released veteran reliever Jay Jackson, tweets Aaron Gleeman of the Athletic. The righty had been outrighted last month and wasn’t on the 40-man roster.

Jackson made 20 MLB appearances with Minnesota early in the year. He struggled to a 7.52 earned run average despite striking out 29 hitters while only issuing nine walks. The longball was the biggest issue. Jackson allowed seven home runs over 26 1/3 innings. It was a marked turnaround from the 2.12 ERA that he’d posted over a similar amount of playing time with the Blue Jays last season.

The 36-year-old Jackson had fired three innings of one-run ball in Triple-A early in the season. He did not pitch there following last month’s outright assignment. Jackson had been on the temporarily inactive list. He’s now a free agent and could find minor league interest once he’s ready to return to action.
