Bryson DeChambeau and Charles Howell III battled to the end last year at LIV Golf Korea and they have picked up where they left off with Sam Vincent joining them for the ride.
The three players each recorded a five-under-par 65 to spring the top of the leaderboard of this season's Korea event at Asiad Country Club in Busan, South Korea on Thursday.
Australia's Cameron Smith was handily poised just two shots behind the leaders in a tie for seventh place.
