From a few weeks ago, here's MLB.com's updated ranking of A's prospects. Note that Daniel Robertson has jumped into the overall MLB top 100 on the basis of his all-around-solid game. New draftee Matt Chapman clocks in fourth while middle infielder Chad Pinder and pitcher Seth Streich have made big jumps up the rankings. Billy Burns has dropped all the way to 17th after beginning the year at no. 9.
