On June 9, 1946, Ted Williams hit the longest home run in the history of Fenway Park. The shot struck a fan, Joseph A. Boucher, a construction engineer from Albany, squarely in the head, according to an account from the Boston Globe. Boucher was sitting in Row 37, Seat 21 of Section 42 in the right field bleachers.
“How far away must one sit to be safe in this park?” asked Ted’s target for the day, feeling his pate tenderly. ... I didn’t even get the ball. They say it bounced a dozen rows higher, but after it hit my head I was no longer interested.”
The home run, one of 38 Williams hit that season, was originally estimated to have traveled 450 feet. The Red Sox later measured the distance from the seat to home plate and determined it to be 502 feet.
The blast, a two-run shot, came off Detroit Tigers starter Fred Hutchinson in the second inning of the second game of a Sunday doubleheader. The Sox won the game, 11-6 (box score) to improve to 39-9 on the season.
While we're talking about Williams, this Esquire piece, an excerpt from "Ted Williams, My Father: A Memoir", by Williams's daughter Claudia, is fantastic.
