Phil Rogers of the Chicago Tribune reports the Cubs are calling up shortstop Starlin Castro and plan on inserting him into the lineup immediately.
The 20-year-old is hitting .376 with one homer, 14 extra-base hits and 20 RBI in 26 games with Double-A Tennessee.
Reports claim manager Lou Piniella plans to start Castro at short, move Ryan Theriot to second base and send Chad Tracy to the minors.
