Brooks Koepka, this year's US Open and PGA Championship winner, was announced as the US PGA Tour Player of the Year, having won a vote by tour players.
The 28-year-old American captured the Jack Nicklaus Trophy after a historic 2017-18 campaign that saw him defend his US Open crown by winning at Shinnecock and then deny Tiger Woods a 15th major title by holding off a final-round rally in August at Bellerive.
Koepka, who missed nearly four months in early 2018 with a left wrist injury, also managed four other top-10 efforts in the season, including second-place finishes at the WGC HSBC Champions and at Colonial.
"Brooks has brought a new brand of athleticism to the PGA Tour and we saw the results this year with his historic season at the major championships," said tour commissioner Jay Monahan.
"These feats were accomplished despite missing significant time due to injury, a testament to his work ethic and perseverance throughout the season."
