LOS ANGELES -- The Los Angeles Dodgers had a strange pregame warm-up for their home opener and a chaotic start to the game, and the two might not be unrelated. Matt Kemp was upset about not being in the starting lineup, and then, suddenly, he had nothing to complain about. Yasiel Puig got benched for showing up late for batting practice, which opened up an outfield spot.One problem solved, for now, but another one lingers.The first couple of innings seemed to reflect the earlier turmoil, with Kemp misplaying a ball, Hanley Ramirez making an error and Hyun-Jin Ryu pitching his worst game as a Dodger.
