SAN FRANCISCO-Wilmer Flores came off the bench to hit for LaMonte Wade, Jr., and he eventually came up with the hit of the night.

Flores hit a flare over the head of Ketel Marte into right field to score Evan Longoria in the bottom of the sixth inning to start the rally that ended up helping the San Francisco Giants to a 6-4 victory over the Arizona Diamondbacks before a crowd of 28,122 at Oracle Park.

With the victory, the Giants lowered their magic number to win the National League West down to four and maintained their two-game lead over the Los Angeles Dodgers in the NL West, who defeated the San Diego Padres 2-1 at Dodger Stadium.

Longoria, who scored the game-winning run reached on a fielding error by Josh Rojas to lead off the inning for the Giants, then Alex Dickerson came off the bench and was hit by a pitch, then Tommy La Stella singled and then Flores flare into right field scored Longoria.

The Giants were not done, as Buster Posey walked to score Dickerson, then Brandon Crawford hit a broken bat single to score Donovan Solano from third base after he came on to run for La Stella and then Posey scored the final run of the inning, when he scored on a wild pitch by Joe Mantiply.

Logan Webb went the first five innings for the Giants, as he allowed one (unearned) run on four hits, walking two and striking out six.

Despite not faring in the decision, the Giants are now 17-2 in the last 19 starts for Webb going back to May 11.

The Giants scored their first run of the game, when Posey scored with the bases loaded and two outs in the bottom of the first inning, as Mike Yastrzemski walked to score Posey.

Diamondbacks starter Luke Weaver struck out the first two batters in the bottom of the first inning, but then Posey doubled, and Crawford and Bryant walked prior to Yastrzemski walking and picking up his 68th run batted in of the season.

Josh Rojas tied up the game in the top of the third inning, when he hit a sacrifice fly that scored Jake McCarthy, who walked to lead off the inning and went to third, when Wade, Jr., was unable to hold on to the pickoff throw from Webb and McCarthy went all the way to third.

McCarthy scored the Diamondbacks second run, as he hit an opposite field solo home run in the top of the seventh inning. It was the third home run of the season for McCarthy.

David Peralta attempted to tie up the game, as he hit a fly ball to the deepest part of the ballpark and was forced to settle for a sacrifice fly that scored Daulton Varsho with the Diamondbacks second run of the inning. Kole Calhoun cut the Giants lead in half, as he singled in Rojas.

Camilo Doval came on in the top of the ninth inning, and despite allowing a double to Geraldo Perdomo that brought the tying run to the plate, Doval was to get Carson Kelly to fly out to Duggar in centerfield and then got Rojas to strike out swinging on a slider to end the game and give Doval his first major league save.

NOTES: Brandon Belt was placed on the 10-day injured list (retroactive to September 27) with a left thumb fracture, and to replace Belt on the roster, Thairo Estrada was recalled from Sacramento.

The 103 wins by the Giants ties the 1962 and 1993 Giants for the most wins since the team moved to California in 1958. Only the 1904 team that won 106 games, the 1905 Giants, who won 105 and they tie the 1912 New York Giants with 103 wins.

With the 103rd win of the season, the Giants became the third team in MLB history to post that wins in a season after finishing under .500 the season before. They join the 1993 Giants and the 1946 Boston Red Sox, who won 104 games on the season before losing in the World Series to the St. Louis Cardinals.

This was the 15th win for the Giants over the Diamondbacks in 17 games this season, and they are the second team that the Giants have defeated at least 15 times this season, as they went 15-4 against the Colorado Rockies. The most wins that the Giants have over an opponent in a single season is the 1961 Chicago Cubs, whom they went 17-5 against that season.

UP NEXT: Alex Wood goes for his 11th win of the season on Wednesday night, as he takes the mound for the Giants, while Merrill Kelly will take the mound for the Diamondbacks in search of his eighth win of the season.
