The Oakland Athletics placed right-handed pitcher Domingo Acevedo on the 15-day injured list on Tuesday due to a left lower back strain.

Acevedo landing on the IL is retroactive to Tuesday, and fellow right-hander Chad Smith was called up from Triple-A Las Vegas in a corresponding move.

Acevedo, 29, has posted a 13.50 ERA in five relief appearances this season. He is in his third major league season, all of which have been spent with Oakland.

Smith, 27, is 0-1 with a 2.25 ERA in three relief appearances with Las Vegas this season. He has not pitched for the Athletics yet, but he came out of the bullpen in 15 games for the Rockies last season, when he went 0-1 with a 7.50 ERA.
