PEORIA, Ariz. -- Jarrett Parker launched his third home run of the spring and added an RBI double, as the Giants slugged their way to an 8-4 victory over the Padres on Thursday night at Peoria Sports Complex.
"I turned Parker loose there 3-and-0 and that was a good piece of hitting," said Giants manager Bruce Bochy.
San Francisco jumped on starter Andrew Cashner for two in the first and three unearned runs in the third -- the final two of which came on Trevor Brown's two-out, two-run single.

The Padres showcased some power themselves, as Jon Jay and Matt Kemp each went deep for the first time this spring.
Jay led off the bottom half of the first inning with a big fly just to the right of the batter's eye. Kemp, meanwhile, took Giants starter Jake Peavy to the opposite field in the third and finished 3-for-4 on the night, bringing his Cactus League batting average to .318.

"He had some really good swings," said Padres manager Andy Green. "Obviously the oppo home run looked good, the line drive to end [his] game looked good, too. Sometimes all you need is a fister to start the day off, and then you start driving the baseball."
Peavy allowed both Padres homers and eight hits overall, as he continued to struggle in Cactus League play. The veteran right-hander has now allowed 14 runs (12 earned) in 12 2/3 innings.
"That's good work for him, a good four innings of work," said Bochy. "He used all his pitches very well tonight. I think that's a good day's work for him. Now, we'll take him up to five or six innings next time."
Cashner didn't fare much better in what became his first rocky outing of the spring (four innings, five runs, two earned runs, four hits). He was done in by an error on third baseman Yangervis Solarte, which led to three Giants runs.

"He had lot of movement on his two-seam," Green said of Cashner. "It was running out of the zone a little bit, and he had a little bit of a tough time commanding the corners. But that movement is a nice thing to have."
San Francisco tacked on three more in the fifth -- including one on Parker's rocket double -- and the lead was never threatened after that.

Giants Up Next: After the removal of a cyst in his pitching arm set him back a couple of weeks, Matt Cain will make his Cactus League debut Friday night at 7:05 p.m. PT when the Giants host the Padres at Scottsdale Stadium. Cain was on the disabled list for 94 games last year, when he posted career-worst numbers, including a 5.79 ERA. Cain pitched a simulated game Monday, throwing 30 pitches to Giants teammates.
Padres Up Next:Brandon Maurer continues his quest for a rotation spot Friday night when the Padres head to Scottsdale to face the Giants. It's an important start for the right-hander, who is transitioning from his old bullpen role, as he's slated to throw four innings and will face several Giants hitters a second time.
