The explanation rests in a mathematical formula created by the baseball analyst Bill James

and introduced in the 1980 Baseball Abstract. James determined that the record of a baseball

team could be approximated by taking the square of team runs scored and dividing it by the

square of team runs scored plus the square of team runs allowed. Because of its similarity to

the geometric method for determining the sum of the angles in a right triangle, he called it the

Pythagorean theorem. - Årron Schatz NYTimes, Jan. 23, 2005.

P.S. Norton Star sent us this picture observed by a student Tosin while walking in New York. Evidently New Yorkers are determined to not forget the quadradic formual:
