A source gave me the heads up a few weeks ago that the Phillies had given Aaron Altherr a few looks at 3B this winter, and now that Keith Law brought up the fact in his article today, I suppose its news fit for public consumption. I was told that he spent some time working out with Eric Chavez this winter, as they share the same agent….Altherr and Chavez, not Keith Law and Chavez. Early reports were positive, and it appears that his performance this spring will determine whether or not the Phillies go forward with the experiment. Altherr was a shortstop in high school, so the move to 3B is not really a huge stretch, certainly not as difficult as trying to become a catcher, or learning how to perfect the double play turn up the middle. Third base, in essence, is a reaction position, so it will come down to his footwork and instincts. This will be one of the more interesting story lines to follow in spring training.
