LOS ANGELES — I’ll admit a columnist cheat here: There are times, in a game that seems out of hand, when you start writing well before it’s over.

Deadlines, y’know. (Yes, even for a 5 p.m. start.)

But with the New York Mets in town for Game 1 of the National League Championship Series, that’s a risk since the Amazins have made a habit of late inning comebacks the last few weeks. (Roaring back from a 24-35 start to make the postseason is an impressive comeback in itself.)

Ah, not to worry Sunday night, at least. Maybe the Mets have run into a Dodgers pitching staff that has gotten on a roll at exactly the right time.

And maybe the seven shutout innings Jack Flaherty provided the Dodgers in Sunday night’s 9-0 Game 1 victory will resonate far beyond the act of giving his team the series lead. Flaherty, brought back to his hometown to join a starting rotation that turned out to need him more than was even anticipated, threw 99 pitches and limited New York to two hits while striking out six. Most importantly, he eased the burden on a bullpen that is in all likelihood going to bear most of the responsibility in this series.

Consider this, as well: Flaherty with seven innings and relievers Daniel Hudson and rookie Ben Casparius with one apiece extended the Dodger staff’s scoreless innings streak to 33, which includes the final 24 innings of the San Diego series. That matches the best postseason stretch in major league history, and there’s a back story here.

The 1966 Baltimore Orioles also recorded 33 scoreless innings in a row … in the World Series … against the Sandy Koufax-Don Drysdale Dodgers, in a four-game sweep. Those Dodgers, notoriously weak offensively, were eighth out of 10 NL teams in runs scored with 606, and didn’t score in that World Series after the third inning of Game 1.

So the Dodgers franchise now has a chance for some psychic payback, 58 seasons later. A scoreless first inning on Monday afternoon will do it, and if nothing else it would mean something to those who were around all those years ago.

A few more shutout innings – a bunch more, actually – would be useful in terms of the ultimate goal, as articulated on Dodger Stadium’s ribbon board after Sunday’s game: “7 wins to go.”

How impressive/important were those seven innings from Flaherty?

“It was just a pitching clinic,” Manager Dave Roberts said. “I thought he did a great job of filling up the strike zone with his complete mix. Used his fastball when he needed to. Just minimized damage. And once we caught a lead, he did a great job of just going after those guys and attacking.

“And for us to get seven innings in a long series was huge.”

He mixed his pitches effectively, got whiffs or called strikes on 28% of his pitches and only had one runner in scoring position. And he got help in the fifth from Kiké Hernández, playing center field, whose fake throw to third base on a bloop single to left center by Jose Iglesias deked lead runner Jesse Winker into confusion, and led to his being thrown out at third and defusing a potential threat.

The break the high-leverage bullpen guys received can’t be overstated, since Roberts confirmed what was expected: Monday afternoon’s Game 2 will be a bullpen game, opener TBA.

For Flaherty himself, that kind of performance in this ballpark absolutely resonated. The kid from Harvard-Westlake, who watched games here and pitched (and won) here in a CIF Southern Section final in 2013 – with, incidentally, a complete game shutout – came up with the performance a kid dreams about, in a big game, for his hometown team, with his mother in the stands.

“I saw some family out there when I was warming up and I had gone to games here with them before, so … (it) just kind of lets you relax a little bit,” Flaherty said. “At least that was the way it was for me tonight.

“This game is a lot of fun and I’ve been lucky to do it since I was a little kid. I’m still lucky to be able to do it today and be put in these positions, which is why I kind of try to describe these games as fun. As high pressure as they get, I just tell the guys it’s going to be fun. We’ve got to remember that sometimes.”

And walking off the mound after the seventh with a smile, getting a big hug from his manager and then coming back out to embrace his mom … yeah, that’s fun, all right. That’s the stuff dreams are made of.
