None of the top candidates for the first overall pick in the upcoming amateur draft seem likely to command the $8.6MM+ bonus slotted for the #1 pick, MLB.com’s Jim Callis writes as part of a draft mailbag. Callis notes that the Diamondbacks would likely save a couple of million on whomever they pick first overall, making the team’s explorations of taking a lesser-ranked prospect first to save even more bonus pool money seem rather needless. “There’s no need to do a discount of $4 million or more, and it’s unlikely there will be enough quality players to spend that much extra money on in later rounds,” Callis writes.
