The Boston K Men began 25 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.

‘Los ponchados de Pedro’: The K Men posted red K signs in the Fenway Park bleachers (Section 39, Row 31) each time Pedro Martinez pitched for the Red Sox, urging the crowd to help count them in Spanish. A decidedly pagan tradition, the then face-painted crew celebrated Pedro’s starts like regional, secular holiday.

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 Daisuke Matsuzaka and Curt Schilling to Josh Beckett, Jon Lester and Chris Sale. Today, the crew records strikeouts each time the team’s ace takes the mound at Fenway.

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.

Each year, longtime K Man and children’s book illustrator and writer Matt Tavares designs new shirts and hats, which we sell on this website to benefit student-athletes in our city. We are committed to using our small role and platform within Red Sox Nation to proudly promote the important work of  The BASE and to provide access to communities that have been excluded for too long.

K Men or K People?

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.
