Koepka holds five Major titles, winning back-to-back US Opens in 2017 and 2018 before achieving the same feat at the 2018 and 2019 US PGA Championship, which he won again in 2023.
Koepka is the only golfer to ever hold two major titles in successive years simultaneously and the first man to successfully defend the US Open title since the 1980s.
His high percentage of majors contrasts with a patchy regular tour record and Koepka himself has said he feels that golf's biggest tournaments are the easiest to win.

That success earned him a spot on the European Tour, prompted progress up the world rankings, and then, courtesy of a fourth-place finish at the 2014 US Open, he added a PGA Tour card to his resume.
Later in 2014, he claimed his first win on the European Tour at the Turkish Airlines Open, he finished eighth in the Race to Dubai standings and was handed the European Tour's Sir Henry Cotton Rookie of the Year award.
Koepka won his first PGA Tour event, the Waste Management Phoenix Open, in February 2015 and with that moved into the top 20 ranked golfers in the world for the first time. He won that title for a second time in 2021.
The US Open double
Koepka recovered from an opening round of 75 with a 66 and 73 to hold a share of the lead heading into the final round together with close friend Dustin Johnson and compatriots Tony Finau and Daniel Berger.
The US PGA Championship double
At Bethpage Black, Koepka sliced out another piece of history for himself and returned to the number one ranking with a fourth major win in the 2019 PGA Championship.
