MLB Trade Rumors reported the official transaction placing Treinen on the IL and recalling Miller.

The ' bullpen just took a massive hit right before October, and it happened in the most frustrating way possible.

The real kicker is the context from the team's transaction log: Treinen suffered right shoulder inflammation while simply warming up in the bullpen on Saturday.

His season is now officially over. Losing a key reliever to a warmup injury is the baseball equivalent of pulling a hamstring while reaching for the TV remote. It is objectively brutal timing for a franchise that is supposed to be gearing up for a deep playoff run.

To fill the void, is bringing back Miller from the Triple-A Oklahoma City Comets. Miller has barely pitched in the majors this year, logging a 5.06 ERA over a microscopic 5.1 innings while dealing with his own shoulder soreness earlier in the season.
