Cameron Smith’s bid to win the FedEx St Jude Championship and become world number one suffered a sizeable blow before he teed off in the final round.

Smith seemingly carded a third round of 67 at TPC Southwind to lie two shots behind leader JJ Spaun, only to be assessed a two-shot penalty on Sunday for playing from the wrong place on the fourth hole in round three.
