TORONTO -- San Francisco's arms have kept the Giants in games thus far this season, and Wednesday’s 4-0 shutout win over the Blue Jays was hardly any different.

The one noticeable change in the theme of the season so far, however, was that Drew Pomeranz received some support from his offense, and enough to earn his first win with the Giants. Before his outing in Toronto, the southpaw had received a total of just two runs of support in his four starts.

“It’s nice to get that one out of the way,” Pomeranz said. “I’m more excited about pitching in the sixth inning today and just being more efficient, and I felt like I was making pitches the whole time.”

On Wednesday, the squad backed his six scoreless innings of two-hit ball by opening the scoring in the fourth with Brandon Belt’s RBI double. The Giants added on in the fifth with Pablo Sandoval’s second homer in as many days, and doubled the score in the sixth, when Buster Posey and Evan Longoria each drove in a run with a double.

“I’m hoping this just really gets the confidence going,” Giants manager Bruce Bochy said. “We had some big hits in both series, and Belt got us going because their guy was throwing really well. We finally broke through there and we had some big hits. Longo, really both games, we had a lot of guys coming through with hits with runners in scoring position. That’s something we’ve been missing, so it was good to get those timely hits.”

Wednesday’s outing for Pomeranz was his ninth career start against the Blue Jays. Entering the finale of the two-game Interleague set between the two teams, Pomeranz was 3-2 with a 4.26 mark against Toronto in 10 career appearances and eight starts. The 30-year-old left-hander was also 2-1 with a 3.76 ERA in six career outings at Rogers Centre, and he bettered all those numbers.

“What a great job, pitching so efficiently,” Bochy said. “He pounded the strike zone so well, had good command of the fastball, a good breaking ball, he used his change occasionally and really just a real nice job. And he got us far enough. Six innings there of just real nice work.”

Sandoval’s homer continued his impressive start to the season. Before the finale of the Giants’ eight-game, three-city road trip, the 32-year-old Venezuela native was hitting. 344/.344/.656 in 21 games. On Tuesday against the Blue Jays, he became San Francisco’s first player this season with a three-hit game, and notched his first home run of the year.

“We hit really well these two games here,” Pomeranz said. “Pablo had a really good day today, and he’s been hitting really well these last couple days, and that’s obviously nice. My goal is to go out there and just not give up any runs or give up anything anyway, just so it makes it a little easier on them, so I definitely enjoyed that.”

Sandoval led off the fifth inning of Wednesday’s matchup with his second homer of the season. It had a 112.4-mph exit velocity, good for the fourth highest among Giants hitters since Statcast began tracking in 2015. His hardest-hit homer -- and only other at more than 110 mph -- was 114.0 mph on April 27, 2015, also against the Blue Jays, off Aaron Sanchez.

“He’s a good hitter, I’ll start with that,” Bochy said. “And I’ve talked about how he can sit and watch some games and get up there and give you a good at-bat, but the ball jumps off his bat. I think he’s got the highest velocity off the bat this year for us. … He’s the one guy who’s finding the barrel consistently.”

Added Sandoval: “I’m healthy, that’s one of the things. When you’re healthy, you can do everything out there. So I’m healthy, I don’t have a problem with my leg now, my shoulder’s free, so I just felt good. So I’m doing everything I can. I come here every day and [go through] my routine to maintain that swing.”

The two-game sweep of the Blue Jays also marked the end of the reunion between Kevin Pillar -- who went 1-for-3 with a double and an intentional walk on Wednesday -- and the Blue Jays, the team with which he spent his entire career before being traded to San Francisco.

“It’s time, I guess, to officially turn the page, not to say that I hadn’t,” Pillar said. “But there was part of me, obviously getting traded, I knew we were coming here shortly after. I got to say bye to a lot of people that I didn’t get an opportunity to say bye to.

“On a personal note, it was a nice way to close that chapter because I felt like leaving here so quickly I didn’t get the opportunity to see a lot of people that meant a lot to me, that maybe I didn’t get a chance to let them know.”

Amid his emotional return, Pillar was excited to see his own team’s offense get a jump start, and match a season high with its third-straight win.

“I’d like to say I had something to do with it, and gave them good scouting reports,” Pillar said. “But you look at this room; there are a lot of talented guys. There are All-Stars in here, guys who have won World Series, it’s only a matter of time.”
