There will be rookie managers in each dugout and a familiar lefty on the mound when the Los Angeles Dodgers begin pursuit of a fourth straight NL West title in Monday's opener against the San Diego Padres. Clayton Kershaw is scheduled to start for the Dodgers while San Diego counters with Tyson Ross, making his first opening day start. Dave Roberts, who played for both the Padres and Dodgers and most recently was on San Diego's coaching staff, was hired as Los Angeles' manager to replace Don Mattingly.
