"The numbers build off the bonus set for the No. 1 pick, which is $7.2 million this year. Every pick from 2-338 is expressed as a percentage of the No. 1 pick, down to $125,000 for the final picks of the 10th round. A team's total budget for the first 10 rounds is the sum of the numbers for all of its picks, so teams that have extra picks and early picks have more money to spend.
Teams can spread the money among their picks in the top 10 rounds in different ways so long as they stay under the total budget. For example, the Astros could sign their No. 1 pick for $5.2 million and spread the extra $2 million among other players. However, if a team fails to sign a player, it cannot apply the budgeted amount for that pick to other players and loses that amount from its overall budget.
Also, bonuses for players signed after the first 10 rounds do not count against the overall budget, unless they exceed $100,000."
The Royals have the 17th-most to spend, with $6.1M.
