Cishek (hip) threw a bullpen session Tuesday with pitching coach Mel Stottlemyre in hopes of fixing his mechanical issues, Ryan Divish of the Seattle Times reports.

EDGE Analysis

Cishek has tossed four total innings in his minor-league rehab assignments this season, but has been experiencing some mechanical issues that he is still attempting to work through. The reliever is set to throw another bullpen session with Stottlemyre before returning to the field for additional rehab outings. It sounds like Cishek still has some work to do before he's cleared to return to the Mariners' bullpen.
