Jones (oblique) was activated off the minor-league injured list Tuesday.
Jones hit the injured list in mid-May with a strained left oblique, an injury which was originally expected to keep him out for days rather than weeks. He played just six games for Triple-A Norfolk prior to suffering the injury but could make his case for a big-league call-up if he hits well upon his return, as the Orioles have turned to players like Stevie Wilkerson and Pat Valaika at second base in recent weeks.
