Randy Johnson
One of the most famous no pitch calls occurred when Arizona Diamondbacks pitcher Randy Johnson hit a bird with a pitch. During a spring training game on March 24, 2001, Johnson's fastball struck and killed a dove that swooped across the infield after Johnson released the pitch. MLB's chief umpire noted that under Rule 8.01(c), umpires can make calls in situations not covered by the rules using "common sense and fair play," and here a no pitch call "was the fairest thing to do." This no pitch call is so well known that there are more Google search results for "Randy Johnson bird" than there are for "Randy Johnson baseball."
