8:01am: Detroit has released Hanrahan, Anthony Fenech of the Detroit Free Press tweets.

7:35am: Tigers reliever Joel Hanrahan will undergo his second Tommy John procedure after failing to progress in his rehab, Jason Beck of MLB.com reports (Twitter links). Hanrahan indicated that he is not yet sure whether he will be able to mount another comeback effort.

The 33-year-old originally had his UCL replaced in May of 2013. He signed with Detroit last year in hopes of returning to the bigs, and re-signed with the club on a minor league deal this season to continue his rehab. He has yet to throw a competitive pitch for the organization.

Hanrahan had looked like a nice bounceback option for a team that has struggled to achieve consistent results from its relief corps, but reports yesterday indicated that he was experiencing problems with his elbow again after already taking additional time to deal with a lack of rehab progress. His most recent consultation appears to have set the course.

During his time with the Pirates over the 2009-12 seasons, Hanrahan was good for 229 1/3 innings of 2.59 ERA ball, logging 10.4 K/9 and 3.8 BB/9 in 229 1/3 innings. That led to a trade to the Red Sox in advance of 2013, Hanrahan’s final season of arbitration eligibility, but things turned south quickly in Boston as poor results were followed in short order by the season-ending surgery.
