The Dodgers placed Treinen (shoulder) on the 15-day injured list Sunday.
Treinen injured his right shoulder while warming up in the bullpen during Saturday's game against the Giants. Per Fabian, the Dodgers suspect that Treinen suffered a capsule injury, and the right-hander will undergo an MRI on Monday to get more clarity on the matter. Bobby Miller was recalled from Triple-A Oklahoma City in a corresponding move.
