Ramirez was claimed off waivers by the Angels on Sunday.
Ramirez turned in a scoreless inning Friday against the Padres, but that's a rarity for him this season, as the right-hander sports a 6.40 ERA and has been charged with three blown saves. Even though he couldn't make it in the Reds' dreadful bullpen, the Angels must have seen something they liked about the reliever, as they'll add the 27-year-old to serve in middle relief.
