PHOENIX -- Dave Roberts' first Spring Training as a manager began Friday, when Dodgers pitchers and catchers reported to Camelback Ranch-Glendale, with the first workout scheduled for Saturday. Despite losing Zack Greinke to division-rival Arizona, misfiring on other big-name acquisitions and having five players recovering from surgery, management is confident the club is positioned for a strong run at an unprecedented fourth consecutive division title and beyond.
