Valdez agreed to a minor-league contract with the Angels on Thursday which includes an invite to big-league camp.
Valdez recorded eight saves for Baltimore last season but struggled overall with a 5.87 ERA, 1.65 WHIP and 45:14 K:BB over 46 innings. He could earn a spot in the big-league bullpen but is unlikely to find himself in a high-leverage role for the Angels.
