SAN FRANCISCO -- "Energy" was an oft-repeated word Wednesday night in the Giants' clubhouse after Hunter Pence hoisted a sacrifice fly to snap a 10th-inning tie and lift San Francisco to a 4-3 victory over the archrival Los Angeles Dodgers.
San Francisco loaded the bases against reliever Thomas Stripling on Gorkys Hernandez's leadoff single, a walk to Conor Gillaspie and Nick Hundley's sacrifice-bunt attempt, which was ruled a fielder's choice when Los Angeles was unable to throw out Hernandez at third base. Pence worked the count full before pulling a fly to left field that was deep enough to score the game-winner.

The outcome left the Giants with a still-woeful 8-14 record. But their mood has changed dramatically since Monday, when Christian Arroyo, the organization's top hitting prospect, arrived from Triple-A Sacramento. On Wednesday, the 21-year-old infielder smashed his first Major League homer, a two-run clout in the seventh inning that launched the Giants' comeback from a 3-0 deficit.
"I think Christian has brought great energy," Giants catcher Buster Posey said.
Arroyo belted his homer off right-hander Sergio Romo, who had spent his entire 12-year professional career in the Giants organization until this season.
One inning after Arroyo went deep, Morse, playing his first game since being promoted from Sacramento as center fielder Denard Span went on the disabled list, drilled a game-tying pinch-hit homer off Pedro Baez. For many Giants fans, the long ball awakened memories of the 2014 National League Championship Series, when Morse's pinch-hit homer tied Game 5 against St. Louis.
"It was almost like that year," Morse said, describing the scene. "... I told [general manager] Bobby Evans that I'm going to turn this ship around as much as I can."
Added Arroyo: "I think him being here is definitely going to change the energy around for us."
Said Dodgers manager Dave Roberts: "It was a good at-bat by Morse. Petey was making good pitches, but he left a fastball a tick out over the plate and he got the barrel to it."
MOMENTS THAT MATTERED
Rookie wakes up Giants: A lot happened to propel the Giants' comeback. They benefited from effective relief pitching and, of course, Morse's homer that set up the 10th inning. But it all started with the home run from Arroyo, who quickly has become an integral part of the team. "Having a 21-year-old in the big leagues is pretty special," Pence said.
Arroyo did not take his home run for granted.
"When I hit it off the bat, I thought it was a double, so I was sprinting around the bases," he said.
Seager the slugger:Corey Seager broke a scoreless tie with a leadoff homer in the sixth inning, sparking a three-run Dodgers rally. The long ball was projected by Statcast™ to travel 462 feet, tied for the longest home run in the Majors this season.

Dodgers:Julio Urias makes his 2017 debut on Thursday in the 12:45 p.m. PT series finale. The 20-year-old lefty pitched twice against the Giants (one start) last season and went 0-1 with a 3.68 ERA and a 1.09 WHIP.
Giants: Left-hander Matt Moore, who will oppose the Dodgers in Thursday's 12:45 p.m. series finale, has faced the Dodgers five times -- all last year. He finished 3-2 with a 4.40 ERA in those assignments.
