Adam Scott led the charge, the 38 year old playing the event for the first occasion and the venue for the first time since the 2008 US Open.
After his relatively slow start on Thursday when a first round of 70 had him well behind the eight-ball, Scott made significant progress each day, a final round of 68 having him finish in outright second place and just two shots behind the leader for much of the event, Justin Rose.
Scott was unable to make any early progress on day four but birdies at his final four holes saw him break clear of a race for second and third place and he earns the US$750,000 second placed cheque.
The earnings take Adam Scott past US$50 million in his PGA Tour career and into 7th place on the all-time career money earners on that Tour, just one place behind Justin Rose who also passed US$50 million this week.
Scott first joined the PGA Tour in 2003 and won that first season when successful at the Deutsche Bank Championship. He has gone on to record a total of 14 PGA Tour victories but has a total of 30 victories worldwide.
Jason Day continued his great record at Torrey Pines the defending champion and two-time winner of the event finishing tied with Rory McIlroy in 5th place.
Cameron Smith produced the best final round of the day (65) to jump 39 positions and finish in a share of 9th while Matt Jones was 13th, Marc Leishman 42nd and John Senden and Cameron Davis 57th.
The winner, Justin Rose, consolidates his position at the top of the world ranking in what was his second event of 2019.
The PGA Tour now moves north to Scottsdale near Phoenix for this coming week's Waste Management Phoenix Open.
