Cameron Smith chasing world No 1 ranking at St Jude Championship

Cameron Smith has a huge chance to win the opening PGA Tour FedEx Cup playoffs tournament and claim the world No 1 ranking, as he surges into the final round two shots from the lead.

As speculation continues to swirl about whether he’ll jump to the rebel LIV Golf circuit, Australian world No 2 Smith birdied two of the last three holes to shoot a three-under 67 at the FedEx St Jude Championship in Memphis on Saturday.

Already the winner of the Tournament of Champions, Players Championship and British Open this year, 28-year-old Smith trails only American leader J.J. Spaun (68) and second-placed Austrian Sepp Straka (68) and is in a three-way tie for third with Americans Will Zalatoris (65) and Trey Mullinax (66).

He is keenly aware that a victory would take him to the world No 1 ranking for the first time after current No 1 Scottie Scheffler missed the cut on Friday.

“That’s been one of my goals probably since the start of the year is to try to get to that top spot,” Smith said. “Try and chase it down.”

Fellow Australian Adam Scott fell to tied 25th, six shots from the lead, after a round of 70, while countryman Cam Davis (67) is tied 36th at five under.

Spaun had a two-putt birdie on the par-five 16th and holed an 18-foot birdie putt on the next hole to claim the 54-hole lead a 13-under 197. Straka was right there with him until he failed to save par from the bunker on the 18th.

Both are first-time winners on the PGA Tour this year, and a victory in a FedEx Cup playoffs even carries even more weight - $A3.78 million to the winner and a guaranteed spot at East Lake for the FedEx Cup finale.

But there are a host of players in contention, with 16 within four shots of the lead, including stars Sam Burns and Tony Finau. But
