(CNN)For Brooks Koepka, picking his favorite major win is akin to choosing a favorite child.
Or at least, what he imagines the feeling is like. The 32-year-old has no children of his own, but the four glistening trophies displayed in his home are equally cherished all the same.
The matching pairs of US Open and PGA Championships cups were all scooped in an unprecedented stretch between 2017 and 2019 that saw the American become the first golfer in history to win back-to-back titles in two different majors concurrently. Before Koepka, nobody had ever won their first four majors inside two years.
