In Mark Frost's book The Grand Slam (compare prices), the author relates how Hagen prepared for the playoff: By partying all night long with entertainer Al Jolson. Hagen, Frost related, stayed out all night with Jolson enjoying "champagne, pretty girls, jokes and laughter." When morning arrived, Hagen stopped at his hotel only long enough to shower and change clothes, then headed to the golf course to face Brady in the playoff.

The carousing - and the fact that Hagen won the playoff anyway, 77 to 78 - helped cement Hagen as a larger-than-life character, and, ultimately, a legend of the game. The fact that it was his second U.S. Open victory, and that he'd go on to win 11 majors total, didn't hurt either.

This was the second of two runner-up finishes for Brady in the U.S. Open; he also placed second to Johnny McDermott in 1911. Brady never won a major, but had 11 Top 10 finishes in the U.S. Open.

This was the first U.S. Open to be played over three days rather than two. Rounds 1 and 2 were played the first two days, with Rounds 3 and 4 played on the third and final day.

A golfer named Willie Chisholm set an unfortunate record at the 1919 U.S. Open: Highest score on an individual hole in a U.S. Open. In the first round, he took an 18 on the par-3 No. 8 hole. That record stood until the 1938 U.S. Open, when another golfer scored a 19.
