Hall is a little closer to Kyle Martin than Hoskins. He has hit a few more HRs than Martin did at Lakewood but the BB/K ratios are similar. The HRs are impressive at Lakewood. It just remains to be seen whether he has the other parts of the hit tool that he would need to succeed at higher levels. This does not mean that guys like Ortiz and Pickett don't have the very same questions at Williamsport. It just means that we really need college players to jump to High A in their first full year to have a good evaluation of their skills.
I actually might take all of Squire's 26-30 group ahead of Hall. Morales is an unknown so really we should see him pitch first, but if he is a mid-90s guy he is probably a better prospect. We know Garcia has already made it to AA (and should be back next week). Howard as a 2nd round pick starts ahead of a 14th round pick on pedigree. Stephen is probably in the same group as Hall. Not a lot of data yet on him. Austin Davis is probably in the majors by the end of the year. Squire's list is also very position player heavy. And he forgot a few (Eshelman?, Tirado?).... Guys like Kyle Young and a number of other second tier pitching prospects are arguably in the same group as Hall also. Just a deep system that unfortunately has few stars at the moment.
