SAN FRANCISCO-Matt Duffy came up with the biggest hit of the game at the most opportune tine for the San Francisco Giants.

Duffy hit a walk-off single with the bases loaded in the bottom of the ninth inning off of Steve Cishek , helping the a Giants to a come-from-behind 3-2 victory over the Miami Marlins before a crowd of 41,889, the 347th consecutive sellout at AT&T Park.

It was the first career walk-off for Duffy in his brief major league career, and the fourth walk-off win of the season for the Giants.

Of the 16 wins on the season, nine of them have been by one run, the most in the majors this season.

Things looked bleak entering the bottom of the ninth inning, as they trailed the Marlins and were 1-16 after the eighth inning and trailing.

This was just the second loss of the season for the Marlins after they led after eight innings, as they fall to 14-2 in such games.

Justin Maxwell struck out to lead off the inning, then Andrew Susac singles, following a Gregor Blanco doubled to send Pinch runner Joaquin Arias to third, and it looked like Ichiro Suzuki deked Arias to staying at third.

Buster Posey, who was given the day off by Bruce Bochy was called on to pinch hit for Casey McGehee and he was walked intentionally to load the bases.

Angel Pagan struck out for the second out of the inning, and then Nori Aoki walked to tie up the game and Duffy ended with a single to left field to win the game.

Sergio Romo came onto replace Ryan Vogelsong in the top of the eighth inning, and struck out Jhonathan Solano to leadoff the inning, Justin Bour and then Dee Gordon doubled the right line. Solano then ran for Bour, and scored the eventual winning run for the Marlins.

Michael Morse, who played for the Giants during the 2014 season and helped them to their third World Championship in five years hit a ground run double in the top of the fourth inning.

Christian Yelich singled off of Ryan Vogelsong with two outs in the inning for the Marlins.

Brandon Belt tied up the game in the bottom of the sixth inning, as he singled in Nori Aoki, who singled to leadoff the inning.

Vogelsong went seven innings, allowing just one run on four hits, not walking a batter and striking out five.

Mat Latos went seven innings for the Marlins, as he allowed one run on seven hits, did not walk a batter and struck out seven,

Blanco picked up three hits for the Giants, asides from the double in the ninth, as he hit an infield hit that Marlins manager Mike Redmond challenged; however after a two minute 19 review, the play was upheld.
