MLB Coverage: Arizona Leads Up Darkhorse Teams Out West

The Arizona Diamondbacks lived through a disappointing 2012 season, after winning the NL West the year before. The D-Backs struggled with injuries early, often teased throughout the summer, but never quite put together a sustained run at either San Francisco or Los Angeles. It’s the defending champion Giants and the free-spending Dodgers sucking up all the media air in the NL West in the spring of 2013. TheSportsNotebook’s MLB coverage today will see if Arizona should be considered in the group of contenders, and we’ll also check on two more potential darkhorses out west, the San Diego Padres and Seattle Mariners.
