On the second Tuesday of July, the stars will sparkle in the San Diego sky. But enough about astronomy. It’s the stars sparkling below, on the glimmering grass of Petco Park, that we’re here to talk about.

If the All-Star Game is a time to celebrate star power, let’s just come out and say it. You know where you find the brightest stars and the most star-studded franchises in baseball at the moment?

In the National League, ladies and gentlemen. The NL has finally won baseball’s star wars.

Think about it. All of a sudden, it’s the NL that’s the league of marquee franchises and must-see rivalries. It’s the league of fire-breathing aces. It’s the league of Buster Posey and Bryce Harper, Kris Bryant and Andrew McCutchen, Clayton Kershaw and Madison Bumgarner.

It’s true — 100 percent true. And we’ll begin proving it in a moment. But first, ask yourself this: When was the last time you could say that?

Not 10 years ago. Not 20 years ago. Not 30 years ago. We’re talking the 1970s, friends. The days of Pete Rose, Johnny Bench and Joe Morgan in Cincinnati. Of Mike Schmidt, Steve Carlton and Greg Luzinski in Philly. Of Willie Stargell and Dave Parker in Pittsburgh. Of Steve Garvey, Ron Cey and Davey Lopes in L.A.

And how long ago was that? Jimmy Carter was president. The Village People had just released “Y.M.C.A.” And CC Sabathia and Kim Kardashian had yet to make their debuts on planet Earth. So we’re talking about 97 lifetimes ago.

Then, of course, the American League took over. From 1983 to 2013, the AL won 21 of 30 All-Star Games (not counting that infamous tie in Milwaukee) and 18 of 30 World Series. Curses were shattered in Boston and on the South Side of Chicago. And the Yankees spent about $4 billion to buy every star who changed planes at LaGuardia.

But however long the AL’s reign of stars lasted, can we agree that it’s over? At least for now?

“I’m an American League guy at heart,” said one longtime executive who has worked in both leagues. “But the National League has the better teams right now. And I don’t think I’m going out on a limb to say the better players are in the National League right now.”

So how do we measure star power? Don’t bother looking at wins above replacement or expected fielding-independent pitching (xFIP). The metrics that tell us most about this shift in the balance of star power are fascinating little trends like this:
