Minor league statistics can be misleading. While they certainly don't mean everything, they do matter to a certain extent. There aren't many bad players who hit .300; just like there aren't many good players that hit .200. However, watching players on a daily basis is always a better idea than just looking at the box score.
Here at TCB, we certainly have writers that know prospects, and especially the Astros, but that doesn't mean we have eyes on each game, each night. And that's where the statistics come in, and perhaps no player currently in the Astros farm system is more of a statistical darling than Tony Kemp.
