SAN FRANCISCO-Jake Peavy probably looked at Jeff Samardzjia, and probably said what ever you can do, I can do as well.

Peavy hit a two-run single in the bottom of the fourth inning, helping his own cause and the San Francisco Giants defeated the Miami Marlins 7-2 before a crowd of 41,886, the 418th consecutive sellout at AT&T Park.

The right-harder went seven innings, allowing two runs on seven hits, walking two and striking out seven on his way to his first win of the 2016 season.

After Denard Span struck out to leadoff the first inning, Joe Panik and Matt Duffy hit back-to-back singles and then Buster Posey made it three in a row with a single of his own to Panik. Brandon Belt then gave the Giants a big run, as he hit a sacrifice fly to Christian Yelich in left field to score Duffy.

Marlins pitcher Jose Fernandez helped out his own cause, as he singled in his first at-bat against Peavy and then scored the Marlins first run of the game, when he scored on a Marcell Ozuna double.

It was one of two hits for Fernandez, who lost for the second time this season against one win. Fernandez went six innings, allowing four runs on seven hits, walking three and striking out five.

Derek Dietrich cut the Giants lead in half in the top of the sixth inning, as he tripled to right-center field to score Yelich from first base after the left fielder led off the frame with a single.

The Giants added another run in the bottom of the seventh inning, as Gregor Blanco tripled for his first hit of the evening and then pinch hitter Kelby Tomlinson singled to left field to score Blanco.

Span came up with second hit of the game to send Tomlinson to third, as he attempted to steal second base with Panik at the plate, Span thrown out by Jeff Mathis and tagged out by Dee Gordon. Bruce Bochy challenged the call, but after a three minute 13 second review, the play was upheld.

Panik picked up his second hit of the night to score Tomlinson from third base. With a chance to blow the game wide open, Hunter Pence struck out with the bases loaded to end the inning.

Matt Duffy, who was honored with his own bobble head picked up three hits on the night and made an outstanding catch in the first inning, as he leaned into the stands to snare a Gordon pop up.

Like Bochy, Don Mattingly also lost his challenge, as he challenged the fact that Dietrich was safe on a Brandon Belt throw to Brandon Crawford. Mattingly thought that Crawford came off the base too early; however after a one minute 29 second review, the play was upheld.

Blanco picked up his second triple of the evening in the bottom of the eighth inning, and then scored for the second time in as many innings, when pinch hitter Angel Pagan hit a sacrifice fly to left field.
