HOUSTON — There is nothing geographically logical about New York and Houston being so intertangled in each other’s sporting existence. Houston didn’t even have major league sports until Bud Adams joined the AFL’s “Foolish Club” in 1960 and gave birth to the Oilers. But it is remarkable how often New York has been on the field for a momentous Houston occasion — and vice versa.

Here are a few of the notable ones from through the years.

April 9, 1965

It was the Mets who were the Astros’ twin brother, yes, both forcing the hands of the Lords of Baseball by, first, becoming charter members in the Continental League, which forced expansion, which is how both entered the National League in 1962 — Houston to much greater success than New York, since the Astros finished higher than the Mets in each of the teams’ first six seasons.

But it was on this date when the most remarkable sporting facility of the day was born: the Astrodome, the Eighth Wonder of the World, the first indoor baseball stadium of its kind. When the Astros and the Yankees played an exhibition game, there was still real grass on the field (and still blinding glass plates as a roof; those plates would have to be blacked out so nobody would be killed by a falling baseball, and ultimately that killed the grass, leading to the invention of artificial turf).

Yankees manager Johnny Keane wanted to rest Mickey Mantle, but Mantle, born in Oklahoma and already an offseason resident of Dallas, wanted to play, and got both the first indoor base hit of all time (leading off the first inning) but the first home run, too, in the sixth, much to the delight of 47,876 people that included President Johnson and his wife, and Texas Governor John Connally and his wife. The Astros won, 2-1, in 12 innings.

Nov. 21, 1965

Joe Namath’s rookie season had proceeded quietly, certainly in relation to how the Jets had acquitted him. He lost four of his first five starts, and tied the other, and even as he guided the Jets to three straight wins after that, he’d enjoyed only moderate success.

But on the afternoon of Nov. 21, 1965, in front of 52,888 people at Shea Stadium, Namath had his official coming-out against the Oilers, throwing for 238 yards and four touchdowns in a 41-14 Jets win that had the crowd screaming from beginning to end. Two of those throws went to fellow future Hall of Famer Don Maynard as the Jets built a 34-0 lead.

“Joe,” Weeb Ewbank said afterward, “became a man today.”

Oct. 15, 1986

The Astros had been a nemesis to the Mets from Day 1. In 1969, the Mets got swept by the Astros in August to fall 10 games behind the Cubs, seemingly killing their playoff dream. Even in an otherwise glorious 1986, the Astros had played the Mets to a virtual draw, and in July four Mets had gotten arrested after getting into a fight at Cooters, a popular Houston night spot.

On this day, they trailed the Astros 3-0 going into the ninth inning of Game 6 of the NLCS, knowing the unhittable Mike Scott awaited them in Game 7. But they scored three in the ninth to tie, survived a game-tying homer by Billy Hatcher in the bottom of the 14th and a desperate Astros rally in the 16th to win a 7-6 game that literally stopped traffic back home and propelled them to the World Series, where they beat the Red Sox for their second championship.

June 17, 1994

You could pick any of the seven games in which this epic Knicks-Rockets NBA Finals battle took place, including June 19, when John Starks’ corner jumper to win the title was grazed aside by Hakeem Olajuwon, and June 22 when Starks famously went 2-for-18.

But the signature night was this, when the Knicks won Game 5, 91-84, to move within a game of the title, but Madison Square Garden’s attention was divided because on all the TV sets all across the arena, the O.J. Simpson car chase occupied the larger portion of the split screen — and the crowd’s attention.

Oct. 21, 2017

The Astros capped a terrific seven-game ALCS by beating the Yankees in Game 7, 4-0. New York has been waiting for a return match every day since.

Vac’s Whacks

If you want a viewing alternative to Jets-Cowboys on Sunday, may I suggest “Seaver,” an hour-long documentary executive-produced and narrated by my pal Eddie Burns, which airs on WNYW, Fox Ch. 5, at 4:30 p.m. For Mets fans, it really is a must-watch. If you can’t resist the allure of football, program the DVR now.

It’s worth it.

Of all the culture-shock-ey things you run into in Houston, the biggest one is just how much they love their brisket down here. It wouldn’t stun me if they serve it with corn flakes, using BBQ sauce instead of milk.

A couple of final chances to reminisce with the ’69 Mets coming up. Art Shamsky, Ed Kranepool and Ron Swoboda will be at the Cradle of Aviation Museum in Garden City on Oct. 16, the actual 50th anniversary of the championship (www.cradleofaviation.org), and they’ll be joined by Cleon Jones and Edgardo Alfonso at 8 p.m. on Oct. 21 at SVA Theater, 333 W. 23rd St., sponsored by Fans for the Cure (212-625-1025).

Carlos Beltran interviewing with the Mets? It would be less surprising to discover in “Top Gun 2” that Maverick and Iceman really did spend years flying together.

Whack Back at Vac

Thomas Retmanski: These interviews Mets ownership are conducting make me laugh. The ownership that interviewed a couple of years ago and came up with Mickey Callaway is the same group that is interviewing now.

Vac: And they are forever in search of 1,000-watt bulbs that light up a room …

Alex Burton: I don’t care how bad an early season OBJ is having. If Jabrill Peppers can’t make the key one-on-one tackle of a helpless wideout at the sidelines 5 yards short of the marker on third down in Patriots territory (they just went down the field for their third touchdown afterwards), then he shows me nothing and the trade stinks.

Vac: As Dave Gettleman would put it: “Ah, but think of how much better the culture is, Alex!”

@michael_spohn: Yankees-Astros a rivalry? No way, different division, different time zones. Forgetabouit!

@MikeVacc: As I wrote, this feels a lot like what Yankees-Royals in the ’70s felt like. And there’s no doubt that was a rivalry, even with one team in Kansas City and the other in New York.

Stephen Hunt: Before it gets away from us, let’s pause a moment to enjoy that play when the Rays nailed Jose Altuve at the plate Tuesday night. I’ve always said the most exciting play in sports is the play at the plate, and was that ever illustrated better than in the fourth inning Tuesday night? That single play was why people become sports fans.

Vac: Granted, I’m a little nerdy for this stuff. But I must have watched that replay about 75 times. Maybe more.
