Brooks Koepka becomes latest star golfer to leave PGA Tour for LIV Golf Series, sources confirm - ESPN

Open winner Matt Fitzpatrick voices his desire to stay with the PGA Tour as golfers such as Brooks Koepka opt to play for LIV.

Four-time major champion Brooks Koepka is the latest golfer to defect from the PGA Tour to the LIV Golf Invitational Series, sources have confirmed to ESPN.

Koepka, 32, is one of the highest-profile players to join the breakaway circuit, which is being funded by Saudi Arabia's Public Investment Fund and is fronted by two-time Open winner Greg Norman.

Koepka, who is ranked 19th in the Official World Golf Ranking, is expected to compete in the first LIV Golf event in the United States, at Pumpkin Ridge in Portland, Oregon, starting June 30.

A source confirmed that Abraham Ancer, who is ranked 20th in the world, also is leaving the PGA Tour for LIV Golf.

4 Collin Morikawa denied rumors that he also was planning to join LIV Golf, tweeting that he is "here to stay" on the PGA Tour and "nothing has changed.".

LIV Golf has now signed eight of the top 50 players in the world; Bryson DeChambeau (ranked 30th) and Patrick Reed (38th) are expected to compete in the event in Portland as well.

PGA Tour commissioner Jay Monahan suspended 17 players, including two-time major winner Dustin Johnson and six-time major winner Phil Mickelson, for competing in LIV Golf's inaugural event outside London two weeks ago.

Monahan had said that tour players who competed in future LIV Golf tournaments without a conflicting-event release would face similar punishment.
