Cameron Diaz was in the stands at Boston's Fenway Park on Saturday to cheer on her Yankee-player boyfriend, Alex Rodriguez, as he helped lead the squad to victory over the Red Sox. They played the Massachusetts gang on Friday and yesterday as well, though those matchups ended in defeat for the out-of-towners. Alex, unfortunately, skipped the last game, however, due to an illness. Cameron and Alex headed north for the series after a stint in NYC, where they continued their string of workout dates with a trip to their gym. They'll be back in the Big Apple in the coming days as he's scheduled to take on the Baltimore Orioles in the Bronx tomorrow. She has been playing the role of supportive girlfriend over the last few months, traveling with Alex to the Dominican Republic for an award ceremony and spending time in Florida during his Spring training. Cameron has taken a few breaks to focus on her own big-screen career, recently picking up a statue herself at Cinema-Con in Las Vegas. The jet-setting will continue for the actress over the next few months as she gears up for the debut of Bad Teacher in June.
