Los Angeles, CA (Sports Network) - Buster Posey and Joaquin Arias each hit a home run as the San Francisco Giants ended the Los Angeles Dodgers' postseason hopes with a 4-3 victory on Wednesday.
The Dodgers needed a win to remain a game behind St. Louis with one game left to play for the NL's final wild card spot after the Cardinals fell to the Cincinnati Reds earlier in the day.
But with the loss, St. Louis will have a chance to defend its World Series championship.
Barry Zito (15-8) allowed two runs on six hits and a walk while striking out six over six-plus innings for the NL West-champion Giants.
Chris Capuano (12-12) surrendered two runs on five hits in a three-plus innings for Los Angeles.
A.J. Ellis hit a two-run homer in defeat.
