Padraig Harrington delivered Tiger Woods a subtle reminder after the Dubliner ended a seven-year winless drought to capture a second Honda Classic title at PGA National.

Harrington won with a par at the second extra hole, the par three 17th, after the 21-year old American Daniel Berger found the water guarding the green en route to a double bogey. It is Harrington's first taste of success on the PGA Tour in 119 events since capturing the 2008 PGA Championship.

In fact, the triple Major winner has contested 176 PGA Tour events since breaking through for a maiden Tour win a decade ago to capture the 2005 Honda Classic virtually across the road at the Mirasol Club. However Harrington has not been totally without victory having won twice since 2008 on the Asian Tour including landing the 2014 Indonesian Open in the first week of December.

And after slumping to World No. 385 mid last year, Harrington as the new No.82nd ranked player had some timely advice for Woods, and seven places higher on the rankings but heading in the opposite direction as the 43-year old Harrington.

"Normally you would be very happy to be seven spots behind Tiger but then at least I am go up the rankings and let's hope he can, and the two of us can start moving upwards," said Harrington. "And I can guarantee it that it was a big help to me Retief Goosen playing that well last week in L.A. and to see players like Tiger and Retief who I have played so much against over the years doing well as Retief is 46 and Tiger's in his 40th year.

"So I hope when Tiger sees players that he also competed against for so long doing well, including myself winning today, then it will help turnaround his game so that he might say: "Oh yes, I've won against those guys before, so maybe I can still win out here".

"So there is a light at the end of the tunnel and it is a positive thing when you see you peers doing well and it's not just some 20-year old kid who hits is miles and you say to yourself 'Hell, how am I ever going to compete."

Victory also has seen Harrington qualify for the Masters after missing out last year for a first occasion since 2000 while he's exempt on the PGA Tour till the end of the 2016/17 wraparound season after also having lost his Tour card late last year at the Wyndham Championship.

And victory has also rekindled Harrington's desire to compete in next year's Olympics.

"Winning my first PGA Tour event here in 2005 was big and winning my first Major at Carnoustie in 2007 was life changing to win this event is career changing," he said.

"I say that given where I have been at in recent years so be back sitting here now as a tournament winner as I will now be back in the feature draws at tournaments.

"It will make a big change to my career and while for the moment I am just enjoying being a winner again.

"But then all wins are sweet and even winning out in Indonesia last year was so enjoyable when I was out there last December, so winning is so much better than anything else.

"Believe or not I would rather win in Indonesia than finish second anywhere else as winning is just fantastic.

"Though this win, as important to my career it will be the next couple of years, will see me back on top of the pile in that I will get better draws, be able to reshape my schedule and world ranking-wise it's a huge lift.

"And I've been telling the guys back home the Olympics is a big goal of mine and I would love to be competing in Rio next year and while it is a big ask, this win is a step in that direction."

Scotland's Russell Knox shared third place and just one shot out of the play-off in posting a final round two under par 68 for five under par tally and tied with England pair of Paul Casey (68) and Ian Poulter (74).

Casey had led overnight but it was Poulter who threw away a first PGA Tour victory in US soil by finding the water on five different occasions over the last 18, including taking a double bogey at 11 and a triple bogey at 14 before ending like Knox with two birdies.

Knox's effort has wrapped-up his Tour card for the 2015/16 wraparound season also has jumped from 98th to 77th on the World Rankings.

The Scot was just three strokes from the lead and with 11 holes to play when the round restarted at 8am local time Monday.

However a three-putt bogey at the ninth did Knox little favour before he regrouped and moved to four under par when he holed a 13-foot birdie at 11.

The first hole of the famed 'Bear Trap' jumped up to bite the Scot when he three-putted the par four 16th from 54-foot before Knox clawed back with back-to-back birdies at the closing two holes, including sinking a 10-footer at the 18th.

It is the second year in succession Knox has been in contention at PGA National after losing out in a play-off a year ago.

"I am very pleased with my effort as it's very long week what with all the rain delays," he said.

"I played very good this week but it was two three-putts when we resumed this morning that hurt but overall I am happy and if I keep banging on that first victory door the hinges are going to fall off one day."

Knox has this week off before returning to competition for following week's Valspar Championship at Tampa Bay on Florida's west coast.

Stephen Gallacher was already in Miami, and some 75-minutes south of the Honda Classic, where he will join fellow Scot Marc Warren for Thursday's starting WGC - Cadillac Championship.

Gallacher posted a final round two over par 72 for a four over par total and a share of 41st place.

"It was a good solid week and I'm really looking forward to heading to Doral as I was sixth there a year ago," said Gallacher.
