The Phillies are among a few teams keeping tabs on White Sox relievers Bobby Jenks and J.J. Putz.

Philadelphia is concerned about the health of Brad Lidge and Chicago could shop Jenks and Putz if they don't get back in the American League Central race over the next handful of weeks.

Jenks has had injury issues of his own, but has recorded back-to-back strong outings.
