Reliever Shawn Chacon, the only significant player on the Pirates' roster who can become a free agent this winter, has approached management to initiate talks toward a contract extension. "My focus is on this team, and I'd love to be a part of it," Chacon said. "If we can get something done, that would be great." Danny Horwits, Chacon's agent, confirmed that he made his client's willingness to stay known to Pirates general manager Dave Littlefield two weeks ago, but there have been no formal talks yet.
