originally appeared on nbcsportsbayarea.com The Giants have their first series win over the rival Los Angeles Dodgers this season, thanks to the bat of Buster Posey and the legs of Steven Duggar. The veteran catcher drove in the speedy outfielder with a single to left field in the bottom of the ninth inning, and gave San Francisco a 2-1 walk-off win over LA on Wednesday at Oracle Park. Posey stepped up to the plate with two on and two outs, and eventually worked a 3-1 count off of Dodgers reliever Pedro Baez.
