The Dodgers, Rangers, and Cardinals, sources say, are showing the most consistent interest in Benson, according to a major-league source. Benson, 34, underwent rotator-cuff surgery in March 2007 and last pitched in the majors in 2006. An executive from a club with interest in Benson said he looks only "so-so," in his throwing sessions. "Better than expected," the exec said, "but not great."
