Cubs claim Cardenas from Oakland, designate DeWitt
The moves were announced on Monday.
Primarily a second baseman, the 24-year-old Cardenas hit .314, drove in 51 runs and scored 70 for Triple-A Sacramento last year.
The 26-year-old DeWitt batted .265 in 121 games with the Cubs last year, his first full season with them after being acquired from the Los Angeles Dodgers in late July 2010. He has a .260 career batting average in 404 games with the Dodgers and Cubs.
