Trade talk involving Kevin Youkilis has intensified in the last 24 to 48 hours, according to Major League sources. The Red Sox have made it clear that the third baseman is available and they are willing to include cash in order to receive a better player in return. In response, a number of clubs have indicated that they have interest in acquiring the three-time All-Star. "He's being shopped everywhere," said one high-ranking official with a National League club. The Diamondbacks, White Sox, Dodgers, Indians and Pirates are among the teams with varying levels of interest in acquiring Youkilis, sources say.
