The A’s made the move Thursday, a day after the White Sox designated Elmore for assignment.
Elmore has a .223 average in 82 major league games, primarily with the Houston Astros. He’s a career .291 hitter with 110 stolen bases in six minor league seasons.
Elmore, who played with A’s infielder Eric Sogard at Arizona State, was a Triple-A All-Star in 2012.
In a corresponding move, the A’s designated infielder Andy Parrino for assignment. He who appeared in 14 games with Oakland last year.
