It begun with two birdies in his opening two holes, but finished with three shots dropped in his final five.
Ultimately Shane Lowry was way off on the final day and unable to replicate the rounds of Phil Mickelson and Jordan Spieth who both came from far back to put a mild amount of pressure on the final group of Brooks Koepka and Jon Rahm.
Spieth shot a round of six under par, while Mickelson rolled back the years to produce an eight under shift to currently lie in third place.
After his fast start, Lowry bogeyed the third and fifth, before birdieing nine and ten, and looking at a potential top five finish.
As many chasers do on the par five 15th, they take on the water and go for the green in two. The water won as Lowry's approach hit the bank and rolled into the drink.
It lead to a double bogey, after he had bogeyed the 14th, and a tied 18th finish.
Seamus Power hit a round of five over par, to finish on seven over par in total and in a tie for 46th.
With these finishes, Lowry will take home $234,000 (€215,180), and Power will bag $54,000 (€49,504).

"Yeah, I mean, it's obviously a little sore right now," said Lowry after his round.
"Yeah, I'm disappointed, obviously. I put a lot into this this week, and when I birdied 11, I thought, you never know here, and yeah, great putt on 12 and then 14 and 15 just killed me.
"It's extremely disappointing. When you're out there and you feel like you've -- I know Jon is 12-under now, but at the time I was out there, I was feeling it. Like it had to go over it on 15.
"I felt like if I made eagle there, and you go back to thinking of lads like Charl Schwartzel birdieing the last four to win and you feel like maybe you can do something special. I tried and I failed. I'll definitely try again. But yeah."
