Because Cap Anson, Ty Cobb, Babe Ruth, Joe DiMaggio, Mickey Mantle, Willie Mays, Hank Aaron, or anyone else you want to name until the mid 1980s didn't have access to high-tech anabolic steroids that Bonds et al did. Steroids and HGH are NOT the same thing as Speed or Greenies.
And yeah, MLB and Japan use slightly different sized balls. Our baseball hasn't changed since 1920, and whether it did even then is debatable.
