Aussie Smith in the mix, chasing shock leader at TPC Boston

AUSTRALIAN Cameron Smith will begin the final round of the PGA Tour's Dell Technologies Championship just two shots behind surprise leader Abraham Ancer.

The pair started tied for fifth with Smith carding a bogey-free four- under 67 to move up to 11 and a share of fourth.

American-born Mexican Ancer upstaged the game's big names with a six-under 65 lifting him to 13 under - he got off to a fast start when he birdied the first three holes at TPC Boston and made the turn in just 30 shots.

Bryson DeChambeau, who won last week's opening FedExCup play-offs tournament, vaulted into joint second place with a 63 that included a tap-in eagle at the par-five 18th.

Englishman Tyrrell Hatton (69) was also one behind after a birdie at the last, where he almost holed his wedge approach shot.

Justin Rose (70) of England is alongside Smith while halfway leader Webb Simpson carded a miserable 76 to drop seven strokes off the pace.

Rory McIlroy (66) and Jordan Spieth (68) are in a group sharing eighth at nine under.

Marc Leishman is next best of the Australians with a 69 leaving him at eight under while Adam Scott had a 73 to slip back to two over.

Tiger Woods carded a 68 on moving day to be seven under in a tie for 16th.
