11-20th rounds teams can sign a player for up to 150K and it not effect their pool in ‘23. Tigers have 15,747,200 allotted to their 1-10th round picks (each pick is assigned a value. If teams don’t sign a 1-10 pick they lose that budgeted amount). Any money they have left over signing 1-10 they can use that budget to sign guys they drafted 11-20th >150K. Baseball draft is just a big math equation. Farris can technically sign for any amount but it can be up to 150K and it only affect the owner’s pocket, and more if they sign guy(s) under slot in their 1-10 rounds.
He could also already been talking to them and said I’ll go pro if you give me 100K. Who knows.
