Lance Berkman said Monday that he's contacted by the Red Sox, Rays, Phillies and Astros. There appears to be ample interest, but Berkman isn't completely certain that he wants to continue his playing career. The 36-year-old recently accepted a volunteer baseball coaching position on the staff at Rice University. "I'm waiting to be blown away by an offer," he told the Houston Chronicle. "If I'm not, I'll be out (at Rice)."
