Brooks Koepka has been a different golfer in major championships. He now has
4 major championship to go along with just 2 non-major PGA Tour victories.
Among active players with at least 2 major victories since 2000,
Koepka has the
highest share of his victories coming in majors
However, wins are a very noisy measure of performance;
is our preferred metric.
In 417 non-major rounds since 2012, Koepka has averaged +1 true strokes-gained;
in 84 major championship rounds, he has averaged +2.3 strokes-gained.
(For reference, averaging +2 true strokes-gained over the course
of a PGA Tour season will typically place you among the top 5 golfers.)
While it is important to remember that this performance gap could be a
product of randomness
it is becoming harder and harder to deny that Koepka elevates
his game on golf’s biggest stages.
