Deadline day produces a wall of abbreviations, delivered at speed by people who assume you already know them. Here is the plain version.
DFA — Designated for Assignment
The most misread term of the lot, because it sounds like a demotion and is really a clock.
When a player is designated for assignment, he is immediately removed from his club’s 40-man roster. That is the point of the move — it frees a roster spot right now, before the club has decided what happens to him.
Then the seven-day window starts. Within it the club must choose one of five outcomes:
| Outcome | What it means for the player |
|---|---|
| Back on the 40-man | Nothing changes; the club found room elsewhere |
| Placed on waivers | Any of the other 29 clubs can claim him |
| Traded | A normal trade, negotiated in the window |
| Released | Free agent |
| Outrighted to the minors | Only if he clears outright waivers first |
What a Waiver Claim Actually Costs
The claiming club does not send anything back. What it takes on is the money still owed on the contract, and it must add the player to its own 40-man roster immediately — which means somebody else on that roster has to go.
That is why good players sometimes clear waivers: not because nobody wants them, but because nobody wants the salary and the roster casualty at the same time.
PTBNL — Player to Be Named Later
A PTBNL exists so a deal can be announced and completed before the final piece is settled. The headline names move now; one name is filled in afterwards.
Three things govern it:
- Six months. The deal must close within six months of the rest of the trade.
- A shortlist. The clubs usually agree in advance on a list of five to ten players the PTBNL will be chosen from — so it is not a blank cheque.
- A fallback. If they cannot agree on a name, they agree on a price instead, and money changes hands.
“Cash Considerations”
The least mysterious term on the list: the return is money, not a player. When you see a club acquired for cash considerations, that is the whole trade.
Why All of This Peaks Right Now
Every acquisition has to fit on a 40-man roster that is already full. So a club that adds three players at the deadline must remove three — and DFAs are the mechanism. The jargon spikes because the roster maths does.
