Clayton Kershaw has some homework to do before his opening-day start for the Los Angeles Dodgers. The reigning NL MVP and Cy Young Award winner needs to figure out how to get ex-teammate Matt Kemp out. Sure, Kershaw watched Kemp hit during his several years with the Dodgers, but now Kemp is part of the opposing San Diego Padres, who bring their retooled lineup to Dodger Stadium in the teams' season opener Monday. ''Clayton's on the move, as far as never looking back and always getting better,'' Dodgers manager Don Mattingly said.
