The Orioles signed Peguero (elbow) to a two-year, minor-league contract Tuesday, Matt Weyrich of The Baltimore Sun reports.
Peguero ended last season on the injured list with the White Sox due to a right elbow strain. The fact that he signed a two-year deal suggests he might have needed surgery, though that hasn't been confirmed. Peguero holds a career 4.26 ERA over parts of five major-league seasons.
