SAN FRANCISCO — The strobe lights flashed above the lockers in the visitors clubhouse at Oracle Park, first green, then blue, purple, white and red. Over the big speaker toward the back of the room, the New York Yankees’ victory playlist blared, leading with the bouncy “Ever Since U Left Me” by French Montana and Max B. Inside a few lockers rested open Coors Light cans.

The party vibe was fitting. As far as season-opening series go, could it have gone much better for the Yankees?

Just about everything went right in the Yankees’ 3-1 win over the San Francisco Giants Saturday evening, which completed the three-game sweep.

“That’s what you want to do,” right fielder Aaron Judge said.

“A good series, obviously,” manager Aaron Boone said. “Just some really big plays, whether it’s doing the little things on the bases (or) I thought we caught the ball really well in the series. A good way to go into an off day and hopefully keep it rolling.”

The Yankees will have a full day to reflect before visiting the Seattle Mariners on Monday, getting a rare Sunday off.

Their run prevention was strong: They allowed just one in the series, tying the mark for the second-fewest in the first three games of a season since 1900.

Their starting pitching was either excellent (Max Fried, Cam Schlittler) or good enough (Will Warren).

Their defense was solid, especially with Ben Rice making several nice picks at first base as he continues to learn the position on the fly, and with four double plays Saturday. The Yankees also went 5-for-6 in their first cracks at the Automated Ball Strike system era. The challenges came in key spots, including the third inning Saturday, when Trent Grisham flipped a strike that was high out of the zone into a ball that turned the at-bat from a strikeout looking into a walk. He then scored on Rice’s double for the Yankees’ first run. Austin Wells later flipped a ball into a called third strike for Tim Hill to end the seventh.

And their offense exploded for seven runs on Opening Day, followed by Judge clubbing a homer in each of the next two games.

“Look,” Boone said, “wins are always hard to come by. You’ll take them when you can get them.”

The Yankees placed a particular emphasis on focus Saturday. Judge said several Yankees encouraged each other before the game to not settle for the series win, but to nail down the sweep.

“We just tried to make it a point pregame today,” he said. “We talked about it. We’ve got to close out a series. That’s what’s going to make a difference between winning a division or end up tying and losing it. So every game matters, and let’s take it on to Seattle.”

Judge was referring to recent Yankees trauma.

They finished with the best record in the American League last season at 94-68, but were tied with the Toronto Blue Jays, who earned the AL East crown by owning the Yankees in their season series. The Blue Jays went on to use their home-field advantage to drub the Yankees in the AL Division Series and later advance to the World Series.

Meanwhile, there were signs that things may already be getting tense in the Giants clubhouse. Their manager, Tony Vitello, has never coached in the majors before and blamed himself for the offense getting shut out over the first two games. (Like he could do anything about it.) He said he got “all fire and brimstone” in a speech to the team before the season, and implied that the team may have been pressing. It would have been helpful if noted Yankees killer Rafael Devers did more than go 4-for-12 with a double, four strikeouts and no walks.

On the other side, Boone appeared cool until the ninth inning Saturday, when closer David Bednar walked the leadoff man (after seeing a called strike three challenged and turned into a ball), then gave up a single to Willy Adames to bring the go-ahead run to the plate. But as Boone nervously held onto the back of his own neck while perched near the dugout steps, Bednar struck out ex-Yankee Harrison Bader and then finished it off by inducing a slow roller to second base for a double play.

Once again, something went right for the Yankees, who went into Opening Day with so many questions about their decision to “run it back” with last year’s roster.

“Guys are pumped up, amped up,” Judge said. “Usually it’s higher-scoring games. But for our starting rotation to come out there and attack the zone and really just dictate the whole ballgame the whole series, it makes it easy on offense. … It was fun. We took care of business. That was the most important thing.”

After a while, the strobe lights stopped, and as the Yankees packed their suitcases for their flight to Seattle, a blue light shone along the walls — another detail gone right.
