"Paul Konerko doesn't have to run hard as long as he hits home runs, but manager Ozzie Guillen admitted he's concerned about the condition of his slugger's left leg.

"I worry about him," Guillen said of Konerko, who hasn't shown any improvement in the past four games since returning from high left calf bruise. "I worry about him because he doesn't want to play that way. When he run the bases, he feel a little embarrassed. We all know what's going on."
