SAN FRANCISCO -- Andrew McCutchen is making quite the first impression on his new team and fans.
He lined the first pitch he got from Jorge De La Rosa (0-1) for a clean single into left-center, his 10th career game-ending hit. His previous walk-off was just last Saturday, when he hit a three-run homer to sink the Los Angeles Dodgers in the 14th inning.
Just what the Giants had in mind when they acquired the 2013 NL MVP from Pittsburgh in the offseason.
"We get a guy like Andrew McCutchen, I said he was going to impact our club. He has shown that," manager Bruce Bochy said. "You couldn't ask for a better guy to be up there."
Kelby Tomlinson walked to start the ninth against De La Rosa, who allowed Gorkys Hernandez's sacrifice before intentionally walking Austin Jackson to bring up Brandon Belt. Belt walked to load the bases for McCutchen.
"They're rare. You don't get the opportunity a whole lot, and when you do, you're not always going to come through," McCutchen said. "I definitely love those situations because those are lasting ones, those are lasting impressions that you're leaving on fans, on teammates, on everyone."
"He came up huge there. You've got to give them credit though, they continued to battle," Arizona catcher Alex Avila said.
Top San Francisco prospect Tyler Beede struck out three and walked five in his major league debut. He allowed two runs and three hits in four innings in place of the injured Johnny Cueto.
McCutchen drew a bases-loaded walk for the Giants' first run in the sixth, then put San Francisco ahead in the eighth by stealing second and coming home on a wild throw by Avila.
McCutchen forced home San Francisco's first run with a nine-pitch walk. Buster Posey followed with a tying sacrifice fly before Evan Longoria's walk loaded the bases again and chased Patrick Corbin. Hunter Pence added another sacrifice fly against Fernando Salas.
A.J. Pollock's two-run double in the first staked Corbin to an immediate cushion.
Corbin, who was trying to earn his first win at AT&T Park since Sept. 19, 2015, struck out nine to give him 29 Ks over his initial three starts. He surrendered three runs and five hits in 5 1/3 innings and walked two.
Jerry Narron managed the D-backs as skipper Torey Lovullo served a one-game suspension.
The Giants struck out 12 times for the second straight night, but did enough for just their third win in the last 11 facing the D-backs.
Lovullo was suspended one game and also fined by Major League Baseball after an altercation with Cardinals catcher Yadier Molina on Sunday.
Lovullo spoke earlier in the day with MLB executive Joe Torre, who explained the suspension.
"I support that, I agree with it, I made some mistakes," Lovullo said. "I'm passionate. I do things because of that passion that might be done the wrong way. And I said the wrong things and I think that led to the whole thing. I have to serve the suspension and I will do it."
Lovullo used a profanity that set off Molina, who charged toward the manager.
As they've done for several other big league debuts, the Giants flew in the area scout who signed Beede, Midwest scouting supervisor Andrew Jefferson.
"I just saw that," Beede said. "That's nice."
Beede gave two souvenir balls to his father, Walter.
Diamondbacks: 3B Jake Lamb, on the DL with a sprained left AC joint, took swings off the tee, groundballs on his knees and threw. He will take Wednesday off before a more extensive workout likely featuring flip throws and live grounders Thursday. "Today was a very encouraging day," Lovullo said. ... LF David Peralta had the night off with a day game Wednesday. ... Arizona traded OF Jeremy Hazelbaker, designated for assignment last Friday, to Tampa Bay for cash.
Giants: RHP Cueto went on the 10-day disabled list with a sprained left ankle. The move is retroactive to Saturday, when he injured himself during an indoor workout. With ace lefty Madison Bumgarner sidelined by a broken pinkie finger in his pitching hand, this marks the second straight season the Giants' top two in the rotation are on the DL. Andrew Suarez is set to start the series finale Wednesday afternoon. San Francisco recalled lefty Steven Okert from Triple-A Sacramento and he was available. ... RHP Jeff Samardzija (right pectoral strain) played catch in the outfield and will soon report to Class A San Jose to get stretched out before being activated.
Lefty Robbie Ray (2-0, 5.73 ERA) takes the mound in the series finale for Arizona opposite Suarez, who will be the Giants' second straight pitcher making his major league debut.
