The Chicago White Sox placed outfielder Alejandro De Aza on the 15-day disabled list Tuesday with bruised left ribs.
The move is retroactive to August 18.
De Aza is batting .281 with six home runs and 44 RBI over 111 games this season.
To fill the roster spot, the White Sox recalled outfielder Jordan Danks from Triple-A Charlotte. Danks made his major league debut in June and hit .265 in 29 games before being optioned to Charlotte earlier this month.
