The Angels have designated reliever Cody Allen for assignment.
The move comes a day after Allen gave up four runs over 2/3 of an inning in a loss to the Rays.
"Unfortunately it was [a move] we felt we had to make for the team," Angels manager Brad Ausmus said. "He worked his tail off. He cared. He wanted to get back to where he was, but nothing was sticking."
Allen has a 6.26 ERA over 23 innings in 25 appearances and lost his closer role in his first season with the Angels.
