Click the link for a one-sentence description, but there are a couple of things to note about this list.
*Six of the top 10 prospects (according to Callis) were acquired by trades in the last 370 days.
*Once George Springer signs, he'll immediately become the #3 prospect in the organization.
If we go back and look at Keith Law's Top 100 prospects list from February, the Astros have now acquired #27 (Singleton), #34 (Cosart), in addition to #42 (Lyles) - who is obviously already in the Majors.
