Cameron Smith survived a wild week and a rollercoaster final round to claim a one-shot victory over Anirban Lahiri at the Players Championship on Monday and collect the PGA Tour's biggest payout, pocketing the winner's check of $3.6 million.

Two shots back of front-running Lahiri going into the weather-delayed final round, the 28-year-old Australian held his nerve when needed, carding a six-under 66 for a winning total of 13-under 275 to capture his second title of the season and fifth of his career.

Lahiri closed with a 69, his disappointment eased by the $2.1 million second-place purse while Britain's Paul Casey returned a final round 69 as well to finish two shots back alone in third.
