Americans are losing interest in playing golf — and it’s taking its toll on business.

Golfsmith, a 150-store golf specialty retailer, has hired an investment bank and restructuring expert as it weighs a possible bankruptcy court filing, according to a report.

The Austin, Texas-based chain, caught in the middle of a downdraft in the sport — roughly 6 million people, or 20 percent of those who regularly play golf, have walked away from the game since 2000 — hired Jefferies to solicit potential buyers and Alvarez & Marsal to help it restructure, according to Bloomberg News.

With the number of people playing golf falling to 24.1 million last year from 30 million in 2000 — when Tiger Woods burst upon the scene, winning three major tournaments — Golfsmith is not the only company feeling some pain.

On Wednesday, Nike said it was exiting the golf hardware business, its worst-performing division.

The company will stop making bags, balls and clubs and will concentrate on shoes and apparel.

In May, Adidas said it would sell its money-losing TaylorMade, Adams and Ashworth golf equipment businesses. It, too, will focus on Adidas golf footwear and apparel.

“The golf industry has been struggling for more than a few years and the biggest catalyst is that millennials are not picking up the game for a whole bunch of reasons,” said NPD Group sports industry analyst Matt Powell.

Among their gripes are that golf is too expensive, too slow, not green and diverse enough, and simply does not “align with their values,” added Powell.

Rounds of golf played dropped sharply at the beginning of the recession and never bounced back, Powell said.

Golfers in the US played 462 million rounds in 2014, the lowest number since 1995, according to Golf Datatech, the most current data says.

And the number of courses is also in contraction — 13 courses opened in 2013, down from 14 in 2012. A total of 157 courses were closed in 2013, up three from 2012, according to the National Golf Foundation.

It doesn’t help that Woods, the sport’s biggest star and Nike’s premier gold pitchman, has been largely sidelined with back injuries for three years.

Woods last won a major in 2008. No other golfer has captured the imagination of fans — or championships — as Woods did.

Equipment sales have not been strong, and retailers began to shed the clubs and bags that were not selling.

Two years ago, Dick’s Sporting Goods laid off more than 500 PGA pros in its stores as golf-related equipment sales declined. The chain used to boast that it employed the second-largest number of pros outside of the PGA.

For its part, Golfsmith confirmed that it “engaged financial advisers to explore potential strategic initiatives” adding that it “has the necessary liquidity to pay the company’s financial obligations.”
