Sardinas was claimed off waivers by the Orioles on Wednesday.
After failing to beat out Erick Aybar for the starting shortstop role during spring training, Sardinas languished while seeing irregular duties off the bench, slashing .163/.226/.163 in 53 plate appearances before the Padres elected to drop him from the 40-man roster. The Orioles evidently still believe there's still some untapped potential in the 24-year-old, who at the very least, should give the team some extra depth at multiple spots around the diamond. He could replace Paul Janish as the club's utility infielder.
