RHP Seth Rosin is headed back to the Phillies, after going unclaimed on waivers this week. The 25-year old pitcher has been assigned to AAA Lehigh Valley after spending the Spring between the Dodgers and Rangers organizations.

Rosin originally came to Philadelphia from San Francisco in the 2012 Hunter Pence trade, and spent all of 2013 as a starter in AA Reading. In 126.2 IP, he earned a 3.92 FIP with a 1.224 WHIP in 26 appearances.

This off-season, Rosin was selected in the first round of the Rule 5 draft by the Los Angeles Dodgers, and sparkled in Spring Training with the team.

In 12 relief innings, he earned a 1.50 ERA with 9.0/1.5 K/BB/9 rates; however, due to the team’s depth and contracts, he was still placed on waivers and claimed by the Texas Rangers.

On the Rangers active roster as a reliever, Rosin made his major league debut against the Phillies on opening day. Notably, he picked up his first major league win the following night during Jonathan Papelbon‘s 9th inning implosion.

Overall, he pitched 4 IP, 3K, 1BB, 3ER before being designated for assignment for Kevin Kouzmanoff on Wednesday.

After being unclaimed on waivers, Rosin was then offered back to the Phillies at a time where the team is scrambling to find any relief pitching support. Phillies relievers have a 5.40 collective ERA in 26.2 IP, and rampant injuries have limited available pitching depth.

Mike Adams, Miguel Alfredo Gonzalez, and Ethan Martin have all been on the DL for weeks.

With Adams appearing ready to return soon and Jonathan Pettibone being called up to start, there isn’t currently room available for Seth Rosin on the active roster.

He’ll begin the season at AAA, and be one of the first relief options called upon in the (extremely likely) case of a need.
