Lightning and generally threatening weather brought play to a halt twice in the final nine holes of the event with Davis and Johnson battling it out for much of that time. Johnson got the break he needed to edge clear when he recorded his fifth birdie of the day at the 13th to move one clear of the Englishman and although he bogeyed the very next hole he moved back ahead with birdies at the 15th and 17th.
Playing the last he enjoyed a two shot lead, found the green with his approach and two putted for par and by then it there was just too much remaining for Davis to do. After missing a great birdie chance of his own at the 17th Davis needed a 2 at the last to tie but the remote chances of that were made even more so by a poor tee shot. For Davis though his runner up finish gets him back on track after a disappointing run of outs since his near miss at the Verizon Heritage Classic where he lost a playoff to Jim Furyk.
It was Davis' fifth second place finish on the PGA Tour and left him still seeking his breakthrough victory. The two times European Tour Champion (2000 Spanish Open and 2004 ANZ Championship) continues to create chances for himself and his time will come.
Johnson set a tournament record of 21 under par, bettering Kenny Perry's previous best of 19 under set in both 2003 and 2005. That was perhaps a reflection on the unbelievably benign conditions all week and greens softened to protect them from the intense heat.
Third place was shared by Jeff Overton, who, like Davis, is closing in on his first PGA Tour title, and Ben Crane. Overton has been twice runner up and now third in three of his last five starts on this 2010 PGA Tour the 27 year old former Walker Cup player making solid progress towards his maiden victory on either the PGA or Nationwide Tours.
Ben Crane continues a great season having won at Riviera earlier in the year and has now finished 4th, 7th and 3rd in his last three starts. He holed a 35 foot putt at the last to share third with Overton.
The leading Australian was Geoff Ogilvy who put behind him some ordinary tournaments in recent months to shoot a final round of 64 and finish in a share of 13th with fellow Australian Matt Jones. Jones's cheque will go close to securing his card for 2011.
Michael Sim continued his comeback from injury with another solid week when 27th, Greg Chalmers was 44th, Jason Day and Aron Price 50th, John Senden 56th, James Nitties 59th and Nathan Green 67th.
The PGA Tour now moves north to Columbus in Ohio for this week's Memorial which sees the return of Tiger Woods.
