Brooks Koepka joins McIlroy and Rahm in star-studded field for $6m DPWT event

Five-time major champion Brooks Koepka has become the latest high-profile addition to the Amgen Irish Open.

Defending champion Rory McIlroy and two-time major winner Jon Rahm will be the headline attractions at the Trump International Golf Links & Hotel in Doonbeg from 9-13 September.

Their Ryder Cup teammates Tyrrell Hatton, Robert MacIntyre, Rasmus Hojgaard, Nicolai Hojgaard and Sepp Straka will also be teeing it up.

And they will be joined by Koepka, 36, who has accepted an invitation from the tournament sponsor alongside home favourite and former European Ryder Cup captain Padraig Harrington.

"I'm looking forward to coming back to Ireland for the Amgen Irish Open," said Koepka.

"I'm excited to experience the challenges of links golf at Doonbeg for the first time, and once again play in front of some of the most passionate fans.

"It's always great to be back playing in Europe."

Koepka has experienced a frustrating season.

He rejoined the PGA Tour in January via a returning member programme after leaving LIV Golf.

Koepka had a stretch of three straight top-20 finishes during the Florida swing in March, including a tie for ninth at the Cognizant Classic in the Palm Beaches.

But that ended up being his only top-10 finish of the year, and he also missed five cuts.

Koepka also failed to challenge for a major title and did not make the PGA Tour's playoffs.

He told reporters he was "pretty disappointed" that his first season back ended prematurely, adding: "I think it's pretty pathetic that I can't get through.

"Zero top-10s basically in two years. To be in the prime of your career and be as good as I think I am, I think that's very pathetic, disappointing. Just need to go home and completely reevaluate everything."

Koepka's putting has been his main issue.

"It's just all on the greens," he said. "I don't know what the deal is.

"[I've] got zero confidence [and] can't putt. I don't know. There's going to be a lot of changes here soon."

Koepka will not be the only notable American at the Amgen Irish Open.

Former Masters champion Patrick Reed will be looking to strengthen his lead at the top of the Race to Dubai standings.

American president Donald Trump is also expected to attend as part of his visit to the Republic of Ireland.
