Halfway co-leaders Stenson and Rahm both carded round of 69 to be alongside Finau at 13-under 203. Finau was his final challenger until he took double bogey on the par-4 14th hole as Rahm made birdie for a five-shot lead, and the rest was easy. Rahm began the tournament slow with a 71 but vaulted into a share of the lead with Henrik Stenson after a second-round 63.
"That Sunday with Tiger is still the most emotionally, most important moment of my golf career", Rahm told reporters. "A couple months later, to win his event, it's really special".
It set up a tense finale with Smith - who partnered Leishman to second place at the World Cup in Melbourne last weekend.
Tournament host Tiger Woods was 17th in the 18-man field after a closing 73 left him at one under. It was quite bad. "I didn't feel I made contact twice being such a small, little ball strike in hitting it sideways there", Woods said.
Still, Tiger said, struggling in the Bahamas couldn't take away from what was an incredible comeback year for the 42-year-old. Rahm grew up on poa annua greens, still isn't entirely comfortable on Bermuda and asked Woods for advice.
"I'm so blessed and so thankful to have the opportunity to have everything turn my way". "To come from where I came from past year at this point, to have the ability to actually play and compete again in the game and do it consistently, is quite wonderful".
"I played in too many this year, and that was from adding an event because I missed the cut at L.A.to qualifying to get into Akron". He said, "I also use it as a learning curve because you can learn all these great things that all these great players have done, and use them for yourself". But the knock-on implications meant that Rose was denied the chance of taking back the World No.1 spot from Brooks Koepka, who opted not to play in the Bahamas.
"Hosting the event and trying to play well, I haven't done a very good job of playing well but it was nice to finish off on that back nine and actually do something positive", he said after picking up four birdies over the final nine holes.
That looked likely to happen heading into the final hole, when Finau sunk a 10-foot birdie to take clear second and knock Rose into third place. It is just titles for now, soon it will be Majors and the World No. 1 ranking.
