If your birthday is today, August 28th, you share your birthday with Jay Witasick, who has plunked Craig Biggio twice. The 211 pitchers who have plunked Biggio have 165 different birthdays. 81 pitchers who have hit Biggio with a pitch share their birthday with another pitcher who has done so, with the most - 4 each - sharing January 21st, April 14th, and September 5th. 4 pairs of pitchers who hit Craig Biggio with a pitch were born on the same day of the same year - Glendon Rusch and Kris Benson on November 7, 1974, Robert Ellis and Rick Helling on December 15, 1970, Livan Hernandez and Leo Estrella on February 20, 1975, and Francisco Cordova and Brian Anderson on April 26, 1972.
But, none of the 211 pitchers who have hit him share their birthday with Craig Biggio.
