Both Baseball America and Baseball Prospectus released their Top 50 Midseason Prospect Rankings. The BA list can be found here and the BP list can be found here. Both lists did not include recently drafted players, although the BP list had a quick preview (where it had Aaron Nola as a guy in the Top 101 discussion).
The Baseball America list had shortstop J.P. Crawford at #23 and ranked Maikel Franco at #50.
Baseball Prospectus ranked Crawford #36 and also included this free scouting report by Chris King http://www.baseballprospectus.com/prospects/eyewitness_bat.php?reportid=134.
