Nevermind...
Walston was selected in the FYPD by SD (was wondering why he was available as a 2019 1st rounder):
1-23
Blake Walston New Hanover HS, Wilmington, N.C. LHP
He's on SD's spreadsheet, just not added on Fantrax.
Found another one:
1-5
J.J. Bleday Vanderbilt OF
Also on KC's spreadsheet, just not added on Fantrax.
