The White Sox, seeking to rebuild their team, have suddenly emerged as the frontrunners. Following the acquisition of infielder Munetaka Murakami (25), a major comeback from a longshot becomes a reality....The White Sox are strengthening their starting lineup, and they view Imai as an "ace pitcher." There are also reports that they are approaching him with a contract of around three years, rather than a long-term one of seven years.
