See Was It So, Shoeless Joe? Here is the letter I sent them:
M. Shribman's review of "The Betrayal" by Charles Fountain ("Was It So,
Shoeless Joe?" Oct. 31) seems to have a major statistical error. It
reads "In the Series they (the White Sox) batted .255, significantly
higher than their .215 season average." But Baseball Reference shows the
White Sox to have a team batting average of .287 during the 1919 season
while batting just .224 during the World Series.
