HISTORY

The Boston K Men began 29 years ago, when Pedro Martinez joined the Red Sox. At every home game that Pedro pitched between 1998 and 2004, the crew — mostly teenagers — plastered K signs symbolizing his strikeouts on the back wall of the Fenway Park bleachers.

After Pedro left the Sox, the K Men mellowed and migrated from Section 39, Row 31 to their current perch above the Green Monster, posting Ks each season for the team’s ace pitcher — from Josh Beckett and Jon Lester to Chis Sale and Garrett Crochet.

K is the symbol for strikeout because it is the last letter of the word “struck,” as in, “most batters who faced Pedro struck out.” We post the K forward if the batter strikes out swinging; backwards if the umpire calls the third strike.

While “The K Men” is the group’s official name, it is a bit of a misnomer. The K Men believe in equal opportunity, with representation from men, women and children.

The K Men are committed to using their role within Red Sox Nation to promote local charities each season. Order your original hats and support The BASE!
