Marc Leishman again had his chances to win the Farmers Insurance Open at Torrey Pines before being derailed by a double bogey just minutes after grabbing a share of the lead.

Leishman, twice a runner-up at the tournament, joined a log jam at the top of the leaderboard when he birdied the sixth hole Sunday but immediately fell back with double at the next.

Finding a fairway bunker with his tee shot, Leishman then missed the green in thick rough and could only advance his ball to the greenside bunker.

It was a disappointing blow for the Victorian who has an enviable record at the California layout and while he slipped back to a share of 20^th with a 1-over 73 Sunday will again take confidence from his overall performance.

It’s been a solid start to the new season for Leishman who made a concerted effort to play more at the back end of last year to get a headstart in the season long FedEx Cup race.

Four cuts made in as many starts and three top-20 finishes suggest the tactic is paying dividends and Leishman is now well set up for his 2017 campaign.

While Leishman was flirting with the tournament lead Quensland’s Cameron Smith went quietly about his business to be the only other Australian under par for the week.

Despite a disappointing opening 73 the 23-year-old ground hard for the next three days to finish T33.

John Senden and Cameron Percy were the only other Australians to play the weekend, Senden succumbing to weekend scores of 76-74 to slip to T64 while Percy found the going even tougher with 76-75 to be T71.

Brett Drewitt, Aaron Baddeley and Greg Chalmers all fell one shot outside the cut line while World Number One Jason Day will feel he has work to do on his game after finishing 3-over.

Stuart Appleby, Geoff Ogilvy and Steven Bowditch also found the going tough and missed the weekend.
