For Schauffele it was his third PGA Tour victory on top of his Greenbrier Classic title in 2017 and the Tour Championship the same year.
The American’s round of 68 was the best of the day and one of only three under 70 on day four, birdies on the 17th and 18th hole enough to force the playoff and eventually the win.
The 25 year old has played beautifully for much of the season despite not winning as he did in 2017 but there have been some obvious highlights including his runner-up finish to Molinari at the Open Championship.
Schauffele should now move to 12th in the world ranking when the revised rankings are finalised, his best standing in the game in his young career. His previous best was 18th.
Finau took the lead into the final round and after his share of struggles throughout the day managed to birdie two holes late to join Scauffele in the lead and take the event into extra time.
Defending champion Justin Rose appeared as if he might yet be the man to beat with a few holes to play but bogeys at his 15th and 18th holes saw him finish alone in 3rd place and four shots from the lead.
Jason Day struggled with a final round of 74 and dropped two spots to finish in a share of 11th, Adam Scott was 18th, Jason Norris 50th and Adam Bland, Jason Scrivener and Cameron Smith 54th and Brett Rumford 75th.
