SAN FRANCISCO-Who would thought that when the San Francisco Giants signed Johnny Cueto and Jeff Samardzija during the off-season, the duo would join Madison Bumgarner making it a big three so quickly.

One night after Cueto threw his third consecutive complete game, Samardzjia went 6.2 innings, allowing just one run on six hits, while walking three and striking out seven and the Giants defeated the San Diego Padres 8-2 before 41,772, the 434th consecutive regular season sellout at AT&T Park.

It was the eighth win in as many tries for the Giants against the Padres, their first eight-game-winning streak against the Padres since June 21, 1987 to April 9, 1988. Going back to last season, the Giants have won 10 in a row over the Padres at AT&T Park and have out scored them 74-27 during that stretch.

Gregor Blanco got the Giants on the board in the bottom of the third inning, as he singled to right field, advanced to second on a Samardzjia sacrifice bunt and then scored when Denard Span singled up the middle.

Jon Jay broke the Giants 23-inning scoreless streak in the top of the sixth inning, as he hit a solo home run off of Samardzjia.

That would be the score until the bottom half of the sixth, when the Giants took the lead for good, as they scored two runs to take a 3-1 lead over the Padres and starter Andrew Cashner.

Joe Panik walked to lead off the inning, and after a Matt Duffy groundout, Buster Posey lined a double down the left field line to give the Giants the lead for good. Brandon Belt then flew out for the second out of the inning, and Brandon Crawford singled in Posey and advanced to second on the throw.

The Giants broke the game wide open in the bottom of the eighth inning, as they batted around. Duffy got the ball rolling with a double, then reliever Keith Hessler intentionally walked Posey and then Belt walked to load the bases. Crawford then cleared the bases with a bases-loaded triple to right field and then Jarrett Parker put the finishing touches on the scoring , as he hit a towering two-run home run to straightaway centerfield for his first home run of the season.

Parker also came up big in the outfield, as he made a great throw to Panik to get Matt Kemp trying to stretch a single into a double to end the top of the first inning.

The Parker throw to get Kemp in the top of the first inning was not the only throw to get Kemp on the evening, as he thrown out on a great throw from Gregor Blanco to Panik, who threw to Duffy at third base for the first out of the eighth inning. Originally, third base umpire Marty Foster called Kemp safe; however after a 1:16 review by the umpires, the call was overturned. That was the second call of the night that was overturned, as Blanco was originally called out on a Samardzjia bunt in the bottom of the third inning; however the Giants challenged and the call was overturned after a 1:52 review.

Former Giants catcher Hector Sanchez came off the bench in the top of the ninth inning and hit an opposite field single Brett Wallace from third base after Wallace led off the inning with a single of his own.

In the loss, Cashner went six innings, allowing three runs on just four hits, while walking four and striking out one.
