TORONTO — The Toronto Blue Jays activated left-handed reliever Brett Cecil off the disabled list on Thursday.

The 29-year-old Cecil is 0-5 with a 5.23 earned-run average in 16 appearances this season. He had been out since May 15 with a muscle strain in his left arm.

Cecil last pitched 2/3 of an inning on May 14 against the Texas Rangers, allowing one hit. Cecil's soreness in his left triceps occurred in the seven-pitch outing, a 6-5 loss.

The Jays optioned reliever Ryan Tepera in a corresponding move.

The Toronto bullpen has struggled this season and has the fourth-worst ERA in the American League at 4.38.

Cecil was stellar for last season's American League East winning Blue Jays, appearing in 63 games and posting a 2.48 ERA and 0.96 WHIP (walks and hits per innings pitched).

Tepera appeared in five games for Toronto this season and is 0-1 with a 5.79 ERA.
