Brooks Koepka and Jon Rahm won't be joining Premier Golf League

The Premier Golf League has taken another huge blow after Brooks Koepka and Jon Rahm joined Rory McIlroy in saying they won't be quitting the PGA Tour.

This now means that should the Premier Golf League go ahead with its proposed plan, organisers would be without the top three players in the world rankings, which would seriously effect investment and viewing numbers.

McIlroy was the first player to confirm he had no interest in leaving the PGA Tour, stating that he "didn't like where the money was coming from" and he didn't want to lose his right to pick and choose which events he plays.

Four-time major champion Koepka has now followed suit after saying that he doesn't like the idea of the majority of the Tour's players being left out, with all the attention being on the top stars playing in the PGL.

“I am out of the PGL. I’m going with the PGA Tour,” Koepka told The Associated Press. “I have a hard time believing golf should be about just 48 players.

"I get that the stars are what people come to see. But these guys who we see win, who have been grinding for 10 or 15 years, that’s what makes the cool stories. I’d have a hard time looking at guys and putting them out of a job.”

Koepka worked his way up to get to where he is today, having failed at the second stage of PGA Tour qualifying back in 2012, the American went through the Challenge Tour before getting a European Tour card and eventually making his way on to the PGA Tour.

“I don’t forget where I’ve come from,” Koepka said. “There are guys from that top 125 who could be the next star.”

Koepka had nothing but high praise for the PGA Tour and the way that it's run, with commissioner Jay Monahan continuing to take the Tour in the right direction and although Koepka is aware of the mega money he could earn with the PGL, the 29-year-old believes there's more to life than money.

“Money isn’t going to change my life,” Koepka added. “There’s something to be said about freedom of playing. I get to chose. To me, it’s not worth it. I’m happy with how things are. When life is good — and it’s real good — you don’t want to change it. I think the PGA Tour is run beautifully.”

Jon Rahm, who has climbed to second in the world rankings, has also turned down the chance to join the Premier Golf League.

Without McIlroy and Koepka, the Spaniard could have been the Premier Golf League's top star, but the 25-year-old sees a long-term future with the PGA Tour.

“I think what I’m going to do is focus on just the PGA Tour,” Rahm told Golfweek. “At the end of the day I’m a competitor. I’m a PGA Tour member and I’m going to stay that way.”

“I’m a young player. The PGA Tour has been doing things extremely well. Hopefully I have a long career ahead on the PGA Tour. The PGA Tour has done such a great job with what we have and I’m really thankful for what they’ve done.”
