Several major league teams have called free-agent pitcher Pedro Martinez about returning to the mound this season, but he has turned them all down. "Very tempting," he said Thursday, "but I have already committed to my kids for the rest of the year and going on vacations, and made plans already with the family." Martinez, 38, has spent most of this summer in the Dominican Republic. "It feels real good to be able to be at home and get to hug Mom every time you want, see her every time you want," he said. "To be able to go to the baseball field and see your kids playing is really something."
