LOS ANGELES -- The last time the Los Angeles Dodgers were in a series with a lot at stake in a stadium filled with revved-up fans stoked by a rivalry, they played their best baseball of the season, outscoring the San Francisco Giants 17-4 over a three-game sweep at AT&T Park two weekends ago.Where did that team go?A sloppy weekend against the last-place Chicago Cubs seemed pretty easy to explain, as the back of the Dodgers' rotation continued to sputter in two of those games.
