LOS ANGELES -- To prepare for tonight's start, his first against the San Francisco Giants this season, Dan Haren studied video of right-handers Odrisamer Despaigne and Josh Collmenter pitching to the Giants lineup over the last few days to see what worked and what didn't.The video guy, John Pratt, offered Haren footage of Andrew Cashner pitching to San Francisco, but Haren didn't bother with it."He throws too hard," Haren said.
