SAN FRANCISCO _ Nick Hundley saved a sparkling start from pitcher Jeff Samardzija, lifting a walk-off home run into the first row of the arcade in the 10th inning.
After producing just one hit over the game's first eight innings, the Giants found a way to squeak out a pair of hits in the ninth to send the game to extra innings before Hundley delivered a 2-1 win over the St. Louis Cardinals by blasting his second-career walk off homer, off reliever Ryan Sherriff.
In doing so, the Giants snapped a four-game losing streak.
Hunter Pence started the comeback charge in the ninth by hitting a ground ball single up the middle. After Joe Panik moved Pence over to second with a sacrifice bunt, Buster Posey tied the game by reaching down to bloop Cardinals pitcher Tyler Lyons' low slider over second baseman Kolten Wong's head.
Despite temperatures that reached more than 100 degrees, Samardzija, who got the ball in place of scheduled starter Chris Stratton (healthy scratch), brought his best stuff. He struck out nine batters, surrendering just one run on two hits over seven innings of work while throwing 112 pitches.
He fanned five straight batters in the second and third, including the three Cardinals he faced in the latter inning. His lone blemish came in the fourth after he surrendered his first hit of the game to the leadoff batter, Jose Martinez, and his second to Dexter Fowler. Martinez scored on Fowler's single past Posey at first base after he advanced to second on a wild pitch.
After that, Samardzija retired nine in a row and 10 of the last 11 batters he faced. The only Cardinals hitter to reach base against him after the fourth was Yadier Molina, who drew a walk in the seventh.
But Cardinals starter Lance Lynn proved to be just as filthy on the hill for the Red Birds, tossing eight-shutout innings of one-hit baseball.
Lynn, who entered the game with a 4-1 record and a 2.13 ERA since July 1, faced the minimum number of batters possible (18) between the second and eighth innings.
