Baseball is constantly evolving, and the Hall of Fame should honour the players who were most valuable in each era under the rules of the time. Ross Barnes was the premier position player of the 1870s thanks to his mastery of the “fair-foul bunt”, a tactic that was eliminated by a rule change in 1877. Ed Walsh was arguably the best pitcher of the first decade of the 20th century because he reportedly could control the spitball so well he could hit a tack on a wall with it. In the 1920s and 30s Chuck Klein used to poke pitch after pitch over the right-field wall at Philadelphia’s Baker Bowl , which was just 280 feet (85 metres) from home plate. And virtually all major league players until 1947 benefited from racial segregation. I’m just as curious to know how many home runs Babe Ruth would have hit if he had faced the likes of “Smokey” Joe Williams and “Bullet Joe” Rogan as I am to know how many homers Mr Bonds would have hit had he never used what he called “flaxseed oil”.
