Me thinks someone has too much time on his hands (the professor that is).
While Barry 'Asterick' Bonds was a lefty check this out:
Hank Aaron - batted right.
George Herman 'Babe' Ruth - batted left
Willie Mays - batted right
Sammy Sosa - batted right
Ken Griffey Jr - bats left
Frank Robinon - batted right
Mark McGwire - batted right
Harmon Killebrew - batted right
Rafael Palmerio- batted left
Those are your top ten home run hitters to date with a 60-40 split amongst them.
Pete Rose, baseball's most prolific hitter was a switch hitter and Ty Cobb batted from the right side of the plate as well. Hank Aaron sits third all time in hits, he batted left as mentioned. Carl Yaz, the last player to hit .400 in a season swung from the left side of the plate.
Nolan Ryan, the prohibitive strikeout kind threw right handed. One could argue that this is true becuase he likely faced more right handed batters who would have a hard time seeing his delivery. However, since the article speaks to a 'rigging' for left handers I feel it is pertinent.
There may be advantages to playing the game left handed but I would hardly agree that the game is rigged for lefties. Anyone who has played the game knows it requires a tremendous amount of skill and athletic ability to play it well.
