PITTSBURGH -- The Pirates finalized their 25-man roster for the start of the 2013 season with several anticipated moves Sunday afternoon.

Placed on the 15-day disabled list were infielder Brandon Inge, who has a sore right scapula (shoulder blade) as a result of being hit by a pitch on March 14, and right-hander Jeff Karstens, who is recovering from shoulder inflammation.

Also added to the DL were left-hander Francisco Liriano (right humerus fracture) and righty Charlie Morton, recovering from Tommy John surgery that was performed last June.

Inge's disabled status is retroactive to March 26, making him eligible for activation on April 10. The others are retroactive to March 22 and will be eligible to return on Saturday.
