The PGA Tour’s ongoing search for investment partners has reportedly winnowed to a small group of heavyweight candidates.

Just days after the PGA Tour turned down a potential investment from Endeavor and after more than a dozen initial suitors sought to strike a deal, Golfweek said the property is now focused on five groups:

Those suitors include:

• Fenway Sports Group, parent group of the Boston Red Sox, Pittsburgh Penguins, Liverpool FC, and most recently, a franchise in the new TGL indoor golf league.

• Acorn Growth Company, an Oklahoma-based private equity firm.
