CHISOX ADD RELIEVER

The Chicago White Sox acquired pitcher Tony Pena from the Arizona Diamondbacks for first baseman Brandon Allen.

What does it give the Chicago White Sox
The White Sox have a very good bullpen already, but adding Pena gives them a needed youth element (since most of their key relievers are in their 30s). He will be another flame-throwing righty option.

What does it give the Arizona Diamondbacks
Allen is a solid lefty hitting prospect who moved up from Double-A to Triple-A this season. If he keeps progressing as he has, he'll provide the D-Backs with another option at first base, a position at which they don't have a lot of depth.
