Current Through 2007 Season

	In 1961 Mickey Mantle set the single season record for home runs hit by a switch hitter when he belted fifty-four long balls with the New York Yankees. Hank Aaron holds the Major League record for most home runs hit in a career without EVER striking out more than one hundred times in a season. Did you know that Frank Robinson is the only member of the 500 Home Runs Club that has more regular season wins as a manager than home runs hit?
