The Chicago White Sox cut ties with slugger Frank Thomas, refusing Wednesday to offer salary arbitration to the two-time American League MVP. The World Series champions also declined to offer arbitration to designated hitter Carl Everett and backup catcher Raul Casanova. Players who became free agents and weren't offered arbitration can't re-sign with their former clubs until May 1. Players offered arbitration have until Dec. 19 to accept and can re-sign through Jan. 8.
