      I assume almost all the 18-year-old appearances are Robin Yount?

      [...] Should Yankee fans expect to win with a 35-year-old short stop? A few months ago, David Pinto tackled just that question and produced the following graph. It shows the total percentage of all plate appearances by age and [...]
