Giants feast in 8th to back Shark, net series

SAN FRANCISCO -- In a legitimate offensive eruption for the San Francisco Giants, they scored twice in Wednesday's sixth inning to snap a tie, then added five eighth-inning runs to pull away for an 8-2 victory over the San Diego Padres.

The Giants, who hadn't scored more than five runs in any of their 16 previous games, inched ahead with the score deadlocked at 1-1. Joe Panik walked to lead off the sixth against Padres starter Andrew Cashner and raced home one out later on a double by Buster Posey, who scored on Brandon Crawford's two-out single.

The uprising made a winner of Giants starter Jeff Samardzija (7-2), who worked 6 2/3 innings and struck out seven while yielding San Diego's lone run. Samardzija's 4-1 with a 1.46 ERA in his last five .

Crawford's bases-loaded triple and a subsequent homer from newly arrived left fielder Jarrett Parker accounted for the eighth-inning scoring off Keith Hessler. The 27-year-old left-hander allowed five runs in two innings in his Padres debut.

Meanwhile, the Giants went 5-for-11 with runners in scoring position after beginning the evening hitless in their last 17 at-bats in those situations.

"It was good to get a win like this, no question," Giants manager Bruce Bochy said. "We hadn't been clicking lately." Referring to San Francisco's fruitful eighth inning, Bochy added, "Hopefully that gets the bats going [so] we keep the line moving a little better."

With the victory, the Giants improved to 8-0 against San Diego this season -- their first eight-game winning streak against the Padres since 1987-88. Of the 72 innings they've played against their Northern California rivals this season, the Padres have only led at the end of two of them.

MOMENTS THAT MATTERED
Throwing the game:
Freshly promoted from Triple-A Sacramento, Parker immediately established his presence in left field by pouncing on Matt Kemp's first-inning hit and throwing him out at second base as he tried to stretch a single into a double. Parker is virtually assured of another start in Wednesday's series finale, since right fielder Hunter Pence is likely to rest his injured right hamstring one more day.

"I knew it was a hard-hit ball into the corner, so it was going to ricochet right back at me," Parker said.

Parker's eighth-inning homer was a towering drive. "I got under it a little bit," he said. "I wasn't really sure if it would keep carrying."

The Federalist haunts SF: Jon Jay opened the sixth inning by launching a solo shot into the standing-room area above the right-field wall. The Padres center fielder owns a .331 career average against the Giants, the second highest mark of any active player with at least 100 plate appearances (trailing only Todd Frazier).

Samardzija's solid: Quality starts are getting to be a habit for Samardzija. He has pitched five in a row and hasn't shown any signs of tiring, throwing 105 pitches on Tuesday night.

Samardzija partly attributed his success to his benign rivalry with the Giants' other top starters, Madison Bumgarner and Johnny Cueto.

"We definitely feed off of each other competitively," Samardzija said. "I haven't watched [other starters] this closely, day-in and day-out, in a while. To come here every day and watch each guy pitch has been great. And to see the success that especially Johnny and Bum have had fuels you to go out and do your part and not be the sour grape, for sure."

Leaving 'em loaded: The Padres loaded the bases with a mini two-out rally in the top of the seventh inning, thanks to a hit, a walk and an error on reliever Josh Osich -- who was ruled to have obstructed Jay on a grounder to first. But Osich came right back and got Alexi Amarista to bounce out to second, ending the threat and stranding the tying runs in scoring position. More >

"We had chances," Jay said. "I had a chance with a man on third, less than two outs [in the third]. … Amarista's ball, if it's a foot to the left, it goes through, two runs score. The effort's there. We're taking good at-bats. It's just one of those things. When it's not for you it's not for you, but you keep showing up to the yard ready to play."

UPON FURTHER REVIEW
The Giants challenged a third-inning ruling after Gregor Blanco was called out at home on a throw from Melvin Upton Jr. and a play at the plate. After a replay review, the call was overturned, Blanco was deemed safe and the Giants had their first run.

Span's RBI single

Another Giants challenge resulted in another big break for manager Bruce Bochy and his team. Kemp appeared to have legged out a triple to open the eighth inning. But a review showed that third baseman Matt Duffy took a short-hop throw and tagged Kemp an instant before he could touch the bag with a headfirst slide. This call also was overturned, marking the second time on the night Kemp had been thrown out attempting to stretch an extra base out of a hit.

"More than anything, we're just pleased with the way he swung the bat tonight," said Padres manager Andy Green of Kemp, who finished 2-for-4. "I think there's really good things to build on there."

WHAT'S NEXT
Padres: James Shields has been very sharp for the Padres this season, but -- because of a lack of run support -- the Padres have won just two of his nine starts. In 13 2/3 innings against San Francisco this season, Shields has allowed three earned runs, and he'll face the Giants again Wednesday, with first pitch set for 12:45 p.m. PT.

Giants: Jake Peavy has faced his former team just four times, posting a 1-1 record with a 2.45 ERA against San Diego. He'll get another chance against in the series finale. Peavy's 1 2/3-inning performance last Friday against the Cubs matched the second-shortest start of his career.
