SAN FRANCISCO -- The Los Angeles Dodgers did what they set out to do. They proved they can beat the San Francisco Giants head to head and they reclaimed first place. Not a bad weekend by the Bay, a three-game sweep at AT&T Park that ended with Sunday night's tense 4-3 win.The Dodgers now lead the NL West by a 1 1/2 games, a crucial cushion with the team still in the midst of its most challenging stretch of schedule this season. How it happened: Jake Peavy pitched well a day after getting traded to San Francisco from the Boston Red Sox, but Hyun-Jin Ryu pitched a little bit better and the Dodgers used some speed and craftiness to beat Peavy.
