The Yankees have signed 16-year-old Venezuelan catcher Jesus Montero to a $2 million deal, according to published reports Tuesday. The Yankees outbid Boston, Cleveland, and the Mets for Montero shortly after the international signing period began late Saturday night, several newspapers reported. The 6-foot-3, 220-pound Montero is viewed as a possible successor to 34-year-old Jorge Posada behind the plate for the Yankees.
