Justin was in his sophomore year in college, pulling a double major in chemistry and baseballogy. For his final research paper for the year, he needed to visit the Major League Baseball Hall of Fame in Cooperstown, New York. The reason for the trip was that, during his preliminary research of hall inductees, he had come across a baseball player whose name had a certain chemical property. Justin decided that he needed to test a theory. Armed with litmus paper, he went to Cooperstown. He toured the site until he came to that player's kiosk. Justin took out his litmus paper and placed it on the player's name. In great anticipation, he waited for the paper to turn blue. To his disappointment, the paper did not change color. Upon returning to campus, Justin decided that his double major was worthless. He immediately dropped chemistry and concentrated all of his efforts into becoming the world's preeminent baseballogist.

What Hall of Fame baseball player has a name that Justin thought would turn the litmus paper blue?
