Dodgers manager Joe Torre Wednesday named Japanese right-hander Hiroki Kuroda to start Opening Day April 6 against the Padres in San Diego. Kuroda will be followed in the rotation by Randy Wolf, Chad Billingsley, Clayton Kershaw and “the mystery person,” said Torre, referring to the fifth starter to be named. That alignment will alternate between right-handers and left-handers over the first four games. Billingsley will start the Dodgers’ home opener April 13 against San Francisco. — Ken Gurnick
