Chicago, IL (SportsNetwork.com) - The Chicago Cubs placed infielder Tommy La Stella on the 15-day disabled list Tuesday due to right rib cage inflammation.
The move is retroactive to April 9.
La Stella, who was acquired from Atlanta in the offseason, was 1-for-6 in two games with the Cubs this season.
The Cubs filled the roster spot by recalling left-hander Zac Rosscup from Triple-A Iowa. He went 1-0 with a 9.45 earned run average in 18 appearances with the Cubs last season.
