PHOENIX -- The Los Angeles Dodgers, it just so happens, open their exhibition season against the team they had so much strife with last year, the Arizona Diamondbacks. The teams begin their Cactus League schedules next Wednesday at Salt River Fields in Scottsdale.Only then will we begin to find out whether the bad blood of last summer lingered through the winter.It's probably fair to say Major League Baseball would prefer they get any hostilities out of the way in Arizona this spring rather than risk having things spill over at the Sydney Cricket Grounds in Australia on March 22, in front of a national late-night TV audience.
