500 at bats for an established major leaguer is very different from a player's first 500 at bats. Arcia, Hicks, Dozier, Plouffe and Hunter all look pretty bad at the first 500 plate appearances. You can't learn to hit major league pitching in AAA. It takes time measured in years. Teams need to invest 1500 plate appearances in their prospects. They need to use those options. The Royals waited longer than 1500 for Gordon and Moustakas. The Twins will need similar partience with their prospects. It would be wise for TD readers to ignore any post using stats early in a career in an argument that the player can't or won't ever hit.
