Clayton Kershaw on the throwback trail

LOS ANGELES -- Clayton Kershaw has, it can safely be said at this point, emerged from Sandy Koufax's shadow.When you win three consecutive ERA titles and two Cy Young Awards in three years, when you throw, arguably, the greatest non-perfect game in history, when your career ERA is the best among any pitcher since 1920 with a minimum of 1,000 innings, there's literally no shadow big enough to obscure you, even that of a living legend.But Kershaw will just never catch up to Koufax in one particular category.
