Atlanta selected Azocar's contract from Triple-A Gwinnett on Sunday.
He'll provide Atlanta with some extra coverage in the outfield after Ronald Acuna (hamstring) was placed on the injured list in a corresponding move, but Azocar is likely to see most of his usage as a late-inning defensive replacement or pinch runner. The 29-year-old had been handling an everyday role at Gwinnett, slashing .270/.348/.420 with two home runs and eight stolen bases over 113 plate appearances.
