a world in a grain of xand

Another men's golf major, two more additions to the list of record low rounds. You'll recall that that number has stood at 62 since 2017, and the list has now, as of the completion of the 2024 PGA Championship, expanded to five entries. Xander Schauffele's round on the first day at Valhalla is the more significant of the two as it provides the first example of a round of 62 leading to a victory, and also the first example of a golfer shooting the new(ish) record low score twice. You'll recall that Greg Norman and Vijay Singh were the only double-featurees on the old list. 

Player	Tournament	Year	Round	Result	Winner
Branden Grace	Open	2017	third	tied 6th	Jordan Spieth
Rickie Fowler	US Open	2023	first	tied 5th	Wyndham Clark
Xander Schauffele	US Open	2023	first	tied 10th	Wyndham Clark
Xander Schauffele	USPGA	2024	first	WON	Xander Schauffele
Shane Lowry	USPGA	2024	third	tied 6th	Xander Schauffele

Two further related topics: firstly I can't hear Xander Schauffele's name without mentally singing "every day I'm Schauffele" in the style of "every day I'm shufflin'" from LMFAO's 2011 dance-floor banger Party Rock Anthem.

Secondly I was struck by the oddity of Schauffele winning the PGA after Scottie Scheffler had won the Masters; in particular that the name of the winner of the second major of the year contained 88.9% (i.e. eight out of nine) of the letters in the name of the winner of the first major of the year (only the "r" is missing). But is this a record? Well, no, or at least not if you allow for the trivial case of the first two majors of the year being won by the same person (and therefore the rating being 100%). That's rare, but has been done a handful of times, most recently by Jordan Spieth in 2015. 

A wander through the archives will convince you that there have been years where the rating has been zero (i.e. no letters were shared) - Floyd and Pate in 1976, Faldo and Irwin in 1990, Immelman and Woods in 2008, Willett and Johnson in 2016 for example. In other years the numbers bounce around somewhere in between. More than 50% seems rare - for instance Phil Mickelson in 2010 shares 55.6% of the letters in his surname with Graeme McDowell, but if you look at the following few years you get 30% in 2011 (Schwartzel/McIlroy), 50% in 2012 (Watson/Simpson), 40% in 2013 (Scott/Rose) and 16.7% in 2014 (Watson/Kaymer). 

I'm going to conclude that the Scheffler/Schauffele sharing ratio is a record, without checking exhaustively, because it seems almost impossible that it isn't, and I can't be arsed to do the legwork. I haven't looked, and am not going to, at the equivalent comparison between second and third majors of the year, but if the upcoming US Open is won by newcomer Rendax Easelchuff I imagine that would also set a record.
