Cameron Smith claimed his first LIV Golf victory in just his second start on the lucrative Saudi-backed circuit with a three-shot triumph over Dustin

Smith, one of 12 major champions in the field of 48 players at Rich Harvest Farms, shot 69-under par in the final round of the 54-hole event to finish at 13 under

"I think I probably had to prove to myself and some other people that I'm still a great player, you know I'm still here to win golf tournaments," Smith said.

"I'm proud of how I hung in there today. I didn't really have my best stuff for the first eight or nine holes, but I hung in there and made some good putts. It was nice."

The stage was set for a final-round showdown between the world's two best golfers as overnight leader Smith opened the day two shots ahead of playing partner

Both players birdied the second hole, but Smith bogeyed the fourth and sixth as Johnson got within a shot before the duo birdied the par-five seventh.

Smith opened up a three-shot lead with a birdie on the par-four eighth, where Johnson carded the first of two consecutive bogeys to get back on the turn four.

Smith is the highest-ranked player to join LIV Golf and finished fourth in his debut two weeks ago in Boston, where he missed a three-way playoff by one shot
