SAN FRANCISCO -- Jeff Samardzija spun another strong start while Jarrett Parker drilled his first home run of the season to pace the Giants past the D-backs, 6-3, on Sunday.
"He's getting his swings off. He played good defense," Giants manager Bruce Bochy said of Parker, who has gone 6-for-13 with seven RBIs and three doubles in three games back from the disabled list. "He's been impressive in the early go here."
Samardzija (7-11) picked up his third consecutive win, a feat he hadn't yet accomplished this season. He tossed 6 1/3 innings, giving up three runs and five hits. But the right-hander allowed three walks, a season high. Entering Sunday, his strikeout/walk ratio ranked third the Majors.
Arizona starter Patrick Corbin (8-11) didn't fare as well, allowing six runs (three earned) over six innings for his second loss of the D-backs' road trip, though he did rack up a season-high 10 strikeouts. The Rockies, who lost to the Phillies on Sunday, remained a half-game up on the D-backs for the first National League Wild Card spot.
"I've got to do a better job getting out of those innings and minimizing damage. Just to try to keep some runs off the board," Corbin said. "I could've a couple times there and kept us in the game there, and we scored a couple runs and had bases loaded a couple times. Probably a different story if I get out of those jams."
Hunter Pence (2-for-4) extended his hitting streak to eight games while tallying two RBIs. Reliever Albert Suarez entered in the seventh and recorded a seven-out save, the first save of his young career. Buster Posey, playing first base, stole two bases in a game for the first time.
"It's a time to try a couple new things," Samardzija said. "It's not the worst time in the world to have some extra ammo in your arsenal come next year. But like I said, we're out here to win ballgames every day. It doesn't matter what the record is."
MOMENTS THAT MATTERED Insurance runs: The Giants tacked on two unearned runs in the fifth thanks to a crafty play by Gorkys Hernandez. He appeared caught in a rundown after rounding second on a double, but D-backs second baseman Daniel Descalso dropped the ball as Hernandez leapt over the top of him. Hernandez was deemed safe without a replay review. Nick Hundley brought home Hernandez and Posey, who was intentionally walked for the second time in the game, to give San Francisco a four-run cushion.
"How about that? When he rounded second, I went 'Oh no.' That's the leadoff double," Bochy said. "Big difference. That was pretty acrobatic. … You notice since they start doing these replays, guys come up with some very creative slides."
Another Parker assist: Parker picked up right where he left off after Saturday's game, delivering a crisp throw home in the fourth to beat J.D. Martinez and keep a potential third run off the board. Ketel Marte popped out hoping for a sacrifice fly, but Parker snagged the ball in left with his momentum moving toward home plate for the Giants' 11th outfield assist of the season -- and second of the series.
"We're banged up. We brought in some young kids to give them some playing time. We go out there and play great baseball. … With what we've been through, it is nice to take a series against a club who's had a very good year." -- Bochy, on the series win
"We lost some opportunities today. You can point to a number of errors, a number of reasons. We just didn't execute in a couple situations, whether it be offensively or defensively or with some pitches on the mound." -- D-backs manager Torey Lovullo
WHAT'S NEXT D-backs: After an off-day Monday, right-hander Zack Godley (5-4, 2.86 ERA) will take the mound at 6:40 p.m. MST on Tuesday against the Dodgers having not allowed a run in back-to-back starts. Godley's thrown 13 consecutive scoreless innings, including six scoreless Aug. 1 against the Cubs in his last start.
Giants: The Chicago Cubs visit AT&T Park starting with Monday's 7:15 p.m. PT contest for a three-game set. Left-hander Matt Moore (3-11, 5.80) makes his second career start against the Cubs, who took three of four against the Giants earlier this season at Wrigley Field.
