LOS ANGELES >> Casey Schmitt admired his work for half a second.

Schmitt didn’t need to watch the ball soar through the night. Nor did he need to see it land halfway up the left-field bleachers. Schmitt, instead, stared at the faces in his dugout — a dugout he ignited with his first career grand slam.

It wasn’t just a swing that shocked ace Yoshinobu Yamamoto and served as redemption for Thursday afternoon’s costly error. It wasn’t just a swing that headlined the Giants’ three homers on Friday night as they beat the Los Angeles Dodgers, 6-2. It was a swing that propelled San Francisco into a tie with Los Angeles at the top of the NL West.

“I was sitting down there looking at the iPad to see how we were pitching guys, and all I heard was the crack of a bat,” said catcher Andrew Knizner, who hit a solo home run for his first hit as a Giant. “I look up and I see Schmitty just kind of pimping it. Subtle, subtle. But swaggy.”

A day ago, Schmitt wasn’t in a position to boast any swagger.

On Thursday, Schmitt muffed a potential double play ball in the ninth inning that would’ve finished off a sweep of the Colorado Rockies. Following Schmitt’s error, the Rockies’ Orlando Arcia flipped a walk-off, two-run single to left field. Following dramatic comebacks on Tuesday and Wednesday, the Giants had to settle for two of three.

Schmitt talked with injured third baseman Matt Chapman, who he is tasked with replacing for the next several weeks, after committing the game-altering error. Chapman, a five-time Gold Glover, provided solace by telling Schmitt that he’s made his own share of errors. The talk helped Schmitt forget about Thursday’s outcome and focus on the task at hand.

“He’s one of the best third basemen to ever do it,” Schmitt said. “I’ve said it before: I’m all ears whatever he has to tell me. Defensively, hitting, he’s been a really big help for me.”

Because of Schmitt, Coors Field went nuts.

Because of Schmitt, Dodger Stadium went quiet.

“I just wanted to come back out and play,” Schmitt said. “For me, I wasn’t coming out here thinking about it. It was just coming out and playing and competing.”

Added manager Bob Melvin: “Hats off to him to turn around the next day and put together an at-bat like that.”

Before Schmitt’s display of power, the Giants set the table with a display of patience.

Jung Hoo Lee began the top of the third by drawing a six-pitch walk. Two batters later, Heliot Ramos walked to put runners at first and second with one out. Two more batters later, Wilmer Flores walked with two outs to load the bases. To Schmitt, Yamamoto’s five-pitch walk of Flores felt intentional.

“It felt like they were trying to put Flo on to get to me in that situation,” Schmitt said.

Did Schmitt take that personally?

“I mean, who wouldn’t? I understand it’s the game. That inner competitor in me, I really wanted that at-bat,” Schmitt said.

The walks were free. The homer was earned.

Yamamoto tossed Schmitt a 1-1 splitter; Schmitt sent the offering towards Glendale. Schmitt’s grand slam wasn’t just his second home run of the season, but his second home run since stepping in for Chapman. In four games as San Francisco’s temporary start, Schmitt is 6-for-15 (.400) with the aforementioned two homers and seven RBIs.

“He has all the tools in the world to be a really good big leaguer. Everyone here knows that. Baseball’s a tough game sometimes,” said Logan Webb, who allowed two runs over seven innings. “Sometimes, you don’t get a whole lot of opportunity. With Chappy going down and Casey sliding in, it’s fun to see for him. I love Casey. I’ve been a big fan of his for a long time. It’s cool to see him shine and do his thing.”

Willy Adames, too, has been shining and doing his thing.

In his first at-bat at part of the rivalry, Adames got the Giants on the board in the first inning with a towering opposite-field home run. The blast didn’t just represent his eighth homer of the season but his third of the road trip. Over his last four games, Adames has raised his OPS from .584 to .635 — still below average, but trending upwards.

“Just looks like there’s way less tension in his swing and we’re seeing the results and the type of stuff he’s capable of doing,” Melvin said.

The home runs from Schmitt, Adames and Kninzer elicited thousands of groans on Friday night. So, too, did the pitching performance Webb, who turned in his 11th quality start of the season and maintained his 2.58 ERA.

Against a team that knows him well, Webb went to a different well. Webb threw 29 cutters against the Dodgers, eclipsing his previous single-game career-high (20) by a healthy margin. Los Angeles couldn’t do anything with Webb’s cutter, hitting into four outs and fouling the ball off 10 times.

“I think that, you know, Logan was doing what he does,” said Dodgers manager Dave Roberts. “He just kind of changes speeds. He doesn’t give in. There’s a cutter, there’s a sweeper in there. The velocity was good tonight.”
