GLENDALE, Ariz. – Chad Billingsley might be the happiest player in Dodgers' camp these days.After 11 months of laborious rehab and 16 bullpen sessions, he is about to face hitters again. That step will come late next week against Dodgers' minor-leaguers, Billingsley said, and it could be followed up fairly quickly by pitching in real games.Shortly after the minor league season begins – on April 3 – Billingsley said he will begin his minor-league rehabilitation assignment.
