How MLB draft money works
The draft is primarily a budget puzzle. Want to know more about the game board and the pieces? Here’s how it all works.
Slot value & the bonus pool
MLB assigns a slot value to each pick in rounds 1–10 (and some related picks). A team’s bonus pool is essentially the sum of those slots. What you actually pay each signee counts against that pool (with some technical exceptions below).
Over slot vs. under slot
If you sign someone over slot, you’re paying above that pick’s assigned number—usually to beat a college commitment or buy talent down the board. If you sign someone under slot, you pay less and bank savings for other picks. Teams routinely mix both in the same draft class.
Edge case: pool overages trigger taxes and can cost future picks if you blow past limits—this simulator simplifies real-world penalties, but the core idea is “you only have so much room to shuffle.”
Leverage: high school vs. college seniors
High schoolers with strong college options often need full slot or well over slot to skip school—otherwise they enroll. That’s why prep bats and arms “cost more” in negotiation even when the pick number looks the same on paper.
College seniors (and many fourth-year players) have little leverage: no NCAA eligibility left, clock is ticking. They frequently sign for well under slot—sometimes tiny numbers in later rounds—so teams can redirect pool money to harder signs.
Sophomores & “extra year” paths
Junior-college sophomores are a classic draft path: they can turn pro after two years at a JC. At four-year schools, eligibility rules (e.g. turning 21 before draft day, or completing three years) mean some players are in the draft as sophomores or “young” juniors—their ask depends on how much they like their remaining NCAA runway vs. the offer.
Edge case: the COVID-era extra year of eligibility blurred class labels for a while; the money story is still leverage—how many real alternatives the player has.
Schools that often keep their commits
Some programs are especially good at getting recruits to campus even when they’re on draft radars—strong development reputations, facilities, education, and culture all matter. Fans often mention schools like Vanderbilt, LSU, Florida, UCLA, Stanford, Virginia (UVA), Mississippi State, Arkansas, Texas, and TCU among the programs that regularly “land” tough commits—but any year can produce surprises.
Edge case: NIL and transfer rules have changed the college calculus a bit, but the draft is still “show me the bonus” vs. “I’ll take the NCAA path.”
