RANCHO CUCAMONGA, Calif. -- Clayton Kershaw was as intense as ever, though he was about to pitch in a one-deck stadium where they hold an air-guitar contest on the roof of the home dugout between innings.Kershaw would later say he had fun, but it didn't look as if he were on any kind of vacation before the game. He followed his pre-start routine to a T. About 45 minutes before first pitch, he strolled out to the dugout and sat there, by himself, wearing a Dodgers jacket, a towel draped over his shoulders, tapping his heel nervously on the dugout floor.
