"The Arizona Diamondbacks are serious about retooling their bullpen over the temptation to pursue home state hero and White Sox free agent first baseman Paul Konerko.

Multiple National League sources said the Diamondbacks have interest in Sox free agent reliever J.J. Putz.

The Diamondbacks could have an advantage because Putz, who had a 2.83 ERA in 60 games and limited opponents to a .204 batting average last season, resides in the northwest suburb of Peoria.

Putz also can close as well as set-up, and he said last season he isn't necessarily looking to close games."
