SAN FRANCISCO-Buster Posey gave the San Francisco Giants their second lead of the night, and this time it held up.

Posey hit a two-run home run off of New York Mets reliever Carlos Torres in the bottom of the eighth inning, as the Giants came back to defeat the Mets 4-2 lead before a crowd of 41,437, the 275th consecutive regular season sellout at AT&T Park.

With the victory, the Giants are the first team in the major leagues to reach the 40-win plateau, after not winning their 40th last season until July 6

It was the third hit of the night for Posey, and it was his first home run since May 3, against the Atlanta Braves, a span of 93 at-bats and first at home since April 29 against the San Diego Padres.

This was Posey’s first multi-hit game at home since April 30 against the Padres

Daniel Murphy’s two-run home run gave the Mets a 2-1 lead in the top of the seventh inning off of Cain.

Matt den Dekker led off the inning with a double down the left field line, as he was the first Mets player to reach second base on the evening against Cain.

That would be the score for all of one-half inning, as Brandon Hicks walked with two outs, went to second on a Jonathan Niese wild pitch and then scored on a Brandon Crawford single to center field.

Cain went seven innings, allowing two runs on three hits, walking no one and striking out three; however he did not fare in the decision.

Niese went seven innings, allowing just two runs, while scattering four hits, walked and struck out and like his counterpart, he did not fare in the decision.

Ruben Tejada broke up the no-hitter with an infield single leading off the top of the sixth inning, and was immediately retired on a double play from Hicks to Crawford to Michael Morse.

Cain did not allow a baserunner until rightfielder Curtis Granderson walked on a 3-1 pitch, as he led off the top of the fifth inning.

Following the Granderson walk, Cain was able to get leftfielder Andrew Brown to ground into a double play, as Hicks made a great play at second base.

Hicks scored the Giants first run of the game in the bottom of the fifth inning, as he tripled off of Niese with one out and then scored on a Crawford sacrifice fly to left field.

The triple by Hicks in that bottom of the fifth inning was the first triple of his major league career.

On the sacrifice fly, Brown came up throwing and throw got away from catcher Travis d’Arnaud, as it gave the Giants a 1-0 lead.

After getting Crawford for the second out of the inning, Niese threw a ball into the ground and it was first called a ball; however Bruce Bochy challenged the call by home plate umpire Rob Drake.

Bochy won the challenge, as it was discovered that Cain was indeed hit on the right foot by the Niese offering and the time of the challenge was one minute and 12 seconds.

Prior to the game, to make room for Cain on the roster, the Giants designated left-handed reliever David Huff for assignment.

Sergio Romo came into the game in the top of the ninth inning, and picked up his 19th save in 21 opportunities.

Jeremy Affeldt pitched the eighth inning, allowing a hit and striking out a batter for his first win of the 2014 season and first ever on his birthday.
