Jay Leng Jr.'s Unique Swing Captivates at U.S. Amateur

ARDMORE, Pa. — There's something wonderfully subversive about watching Jay Leng Jr. hit a golf ball. In an era where swings are optimized to the hundredth of a degree, where launch monitors dictate every angle and club designers chase ball speed like it's the holy grail, here comes a Stanford junior with a motion that looks like it was sketched in a fever dream—and it absolutely works.

The Swing That Shouldn't Work (But Does)

Ask Leng to describe his swing, and he doesn't reach for technical jargon. "I'd say it's art," he told reporters after the second round of the 2026 U.S. Amateur at Merion East. And honestly? He's right.

Picture this: the takeaway moves inside, but before the club reaches shoulder height, Leng is already turning back toward the ball with a slightly closed face. The backswing is what he and Stanford coach Conrad Ray diplomatically call "abbreviated." The follow-through is even more chaotic—the shaft gets nearly parallel to the ground before whipping around to whatever finish feels right in that particular moment. No two swings are identical. Sometimes his feet leave the ground entirely when he's really going after one.

It's mesmerizing. It's unconventional. And right now, it's carrying one of amateur golf's hottest players through the nation's most prestigious amateur championship.

A Self-Taught Revolution

The current iteration of Leng's swing was born right before high school. After working with a single coach through his junior years, Leng decided to strike out on his own and trust his instincts. The abbreviated backswing emerged because he simply hit the ball straighter that way. The finish? That's pure instinct.

"I don't really think about my swing too much," Leng explained. "I guess just trying to hit the shot that I'm trying to hit produces that finish, and I just don't really worry about how it looks."

In golf's current climate of biomechanical obsession and swing-plane perfectionism, this approach feels almost radical. Leng doesn't care what the motion looks like in slow-motion video. He cares where the ball goes.

From Struggling Summer to Surging Star

What makes Leng's presence at Merion even more compelling is his trajectory. The summer of 2025 was a slog—a T-19 at the Northeast Amateur, T-46 at the North and South Amateur, T-103 at the Western Amateur. He didn't even qualify for the U.S. Amateur at Olympic Club.

But a simple grip change on the putter—switching to a claw grip—transformed everything. This summer has been an entirely different story: runner-up at the Northeast Amateur, T-5 at the Southern Amateur, and then the crescendo at the Western Amateur at Beverly Country Club.

At Beverly, Leng defeated No. 1 junior Miles Russell in the semifinals before dismantling Vanderbilt's Michael Riebe 5&4 in the final. In doing so, he became the fifth Stanford Cardinal to win the third-oldest amateur event in American golf, joining a lineage that includes Tiger Woods.

Match Play at Merion Awaits

Now Leng brings his homemade swing to one of American golf's most demanding canvases. Merion East doesn't reward conformity—it rewards creativity, imagination, and the ability to manufacture shots. For a player whose entire game is built on feel rather than formula, this could be exactly the stage where his unorthodox approach shines brightest.

Watching Leng navigate Merion's storied white-flagstick test will be one of the week's great pleasures. Every swing is a small act of defiance against golf's obsession with mechanical perfection. Every follow-through that ends somewhere slightly different is a reminder that there's more than one way to play this game.

The Takeaway

Jay Leng Jr. is proof that authenticity still has a place in competitive golf. His self-taught swing might not fit any textbook, but at the 2026 U.S. Amateur, it's fitting beautifully on Merion's demanding layout. In an age of optimized conformity, Leng's homemade motion is indeed what he calls it: pure art.
