The San Francisco Giants activated Joaquin Arias from the disabled list on Friday, more than two weeks after the reserve infielder underwent an emergency appendectomy.
Arias started 23 games for the World Series champs this season before going on the disabled list July 8. Prior to that, Arias was batting .282 with 10 RBIs in 60 games.
To make room, the Giants optioned right-handed reliever Jake Dunning to Triple-A Fresno (PCL).
San Francisco also acquired pitcher Guillermo Moscoso from the Chicago Cubs in a trade between two clubs playing one another. Moscoso has appeared in 57 games in the majors with Texas, Oakland and Colorado, but has spent this season with Chicago's Triple-A team in Iowa.
