In his daily minor league wrapup, Steve Potter reports:
Multiple new players took fielding practice on Schmidt Field, the four players mentioned above along with Lou Albrecht, Aidan Miller, Kehden Hettinger, Devin Saltiban, TayShaun Walton, Avery Owusa-Asiedu, Pierce Bennett, Trent Farquhar and Bryson Ware.
Pitchers Brandon Beckell, Hunter Loyd, Ethan Chenault, Luke Russo, Casey Steward, Cam Brown, Jake Eddington, George Klassen, Trey Dillard, Chase Hopewell and Brayden Tucker began their throwing programs.
I've bold-faced Bennett and Beckell above, because these players would not have been permitted to participate in these drills had they not been officially signed. Neither signing has been confirmed by the Phillies, nor bonuses reported by national sources, but this is clear confirmation that they have signed.
