Rory McIlroy described his record-breaking third FedEx Cup victory as a "proud moment" for the PGA Tour amid the circuit's ongoing battle with the LIV Golf Invitational Series.
McIlroy saw off world number one Scottie Scheffler in a dramatic final round to triumph at the Tour Championship on Sunday, becoming the first three-time winner of the FedEx Cup.
The 33-year-old, who also claimed the title in 2016 and 2019, moved clear of two-time champion Tiger Woods, who was victorious in 2007 and 2009.
Away from the course, McIlroy has emerged as one of the most prominent critics of the controversial Saudi Arabia-backed LIV series, which is headed up by Greg Norman and counts the likes of Phil Mickelson, Bryson DeChambeau and Sergio Garcia among its star-studded field.
McIlroy chose to reaffirm his commitment to the PGA Tour after clinching a one-shot victory over Scheffler in Atlanta, saying: "It means an awful lot.
"I believe in the game of golf, I believe in this tour in particular, I believe in the players on this tour.
"It's the greatest place in the world to play golf, and I've played all over the world.
"This is an incredibly proud moment for me, but it should also be an incredibly proud moment for the PGA Tour. They've had some hard times this year, but we're getting through it.
"That was a spectacle out there today – two of the best players in the world going head-to-head for the biggest prize on the PGA Tour. I hope everyone at home enjoyed that."
McIlroy, who began his final round at the PGA Tour's season finale six strokes off the lead, also acknowledged Scheffler's shortcomings turned the tide in his favour.
"I've been in the final group here three of the past five years, starting with Tiger in 2018 and that incredible scene. Then to get the better of Brooks [Koepka] in 2019 was awesome," he added.
"Another final group here – I didn't give myself much of a chance teeing off today – I thought, six behind, I thought it was going to be really tough to make up.
"My good play, and Scottie's not-so-great play, and it was a ball-game going into the back-nine."
