The main weakness in an otherwise strong Detroit Tigers prospect pipeline, is the struggle to land quality talent in the high rounds beyond the first. Matt Manning, Alex Faedo, Casey Mize, Riley Greene, and Spencer Torkelson is quite a haul with first round picks for general manager Al Avila, but of course two of those were first overall selections, while Manning and Greene were both top ten picks. Where the Tigers have scuffled is in rounds two through five, where you need to land a good prospect with some regularlity.
The 2020 draft class may be the one to turn things around in that regard.
