ANAHEIM -- The Angels selected the contract of right-handed reliever Deolis Guerra on Saturday, optioning reliever A.J. Achter to Triple-A Salt Lake in the corresponding move.
The team also designated Minor League reliever Al Alburquerque for assignment, clearing a spot on the 40-man roster for Guerra.
Guerra, 27, was re-signed by the Angels during Spring Training and showed promise before undergoing an emergency appendectomy on March 29. He has since thrown in Tempe, Ariz. in extended Spring Training and threw five innings over three appearances with Salt Lake.
Angels manager Mike Scioscia feels Guerra showed plenty of Major League ability during Spring Training before the emergency surgery.
