The North Siders may be on the verge of adding some muscle to their lineup.
Pena would fill the void left behind by Derrick Lee, and allow second year outfielder Tyler Colvin to remain in right field. The Cubs traded Lee to the Braves last August and Colvin filled in at first base off and on.
The deal could be finalized on Wednesday.
