Pushing the cut risk around: roster status (2) raises it, share of appearances as a starter (1) lowers it, this season's WAR raises it.
Context the model does not weigh: ZiPS projects 1.2 WAR; 10 SP on the 40-man.
Trained on every 40-man roster snapshot since 2011 and what happened in the following 90 days; it sees roster status, options, service, history and last season's line, not this season's performance or the club's intentions. How well it does.
Is there a job for him next year?
MIA returns 10 SP on the 40-man once nobody leaves; about 8 SP jobs survive a normal winter. By his own recent record he ranks 8th among the returners (-0.0 WAR against a bar of -0.0), which the calibrated model turns into 71% kept through the tender deadline. Ranked by ZiPS and Steamer instead, which credit his longer track record, he is 7th (0.6 WAR, bar 0.4), worth 87% kept on the same model.

Departing free agents are excluded; players on club, mutual or player options are counted as returning. The kept probability is calibrated on every September since 2012 using the recent-record projection; the ZiPS/Steamer reading uses the same model with a different ranking, so treat it as a second opinion rather than a calibrated number. Salary enters once arbitration projections publish in October.
October: Eligible once reinstated
On the 60-day IL before the cutoff, so he is on the eligibility list. He has served the 60 days (173), so the only step is reinstatement: the club must open a 40-man spot and a 26-man spot before the series roster is submitted.
The post-season eligibility list is fixed at noon ET on September 1: everyone on the 40-man, the 60-day IL or the military list at that moment, who then stays there without interruption. Attachment 25 (Major League Rule 40)
What happens if the club…
- option him to the minorsBLOCKED
- Not while he is on the injured list. He must be healthy and reinstated first; a rehab assignment (20 days, 30 for pitchers, with his consent) is the only way to send him down injured.
- Injured players cannot be sent down
- designate him for assignment (or put him on outright waivers)
- The club has 7 days to trade him, pass him through outright waivers, or release him; he is paid at the major-league rate and keeps accruing service in the meantime. On outright waivers any club can claim him for $50,000, worst record first, and the claiming club takes his contract. If he clears, the club can outright him to the minors and he has no say; he stays under club control on a minor-league deal. He would then be Rule 5-eligible and would hold XX-D rights against any future outright. Post-season: an outright after the September 1 cutoff ends his automatic eligibility. He could only return as an approved injury replacement, and only if he accepts the outright and stays on a minor-league reserve list in the organization without interruption; a release makes him ineligible for anyone this October. Because he is on the injured list he cannot be outrighted until he is healthy and reinstated, so a DFA now would have to end in a trade or a release.
- Designated for assignment: 7 days · Outright waivers · Article XX-D: the right to walk
- release him
- Release waivers cost a claiming club $1 but the claimant assumes the whole contract, so expensive players clear. The club owes the full unpaid balance of this season's salary, offset by whatever another club pays him this year. A released player is not post-season eligible for any club this year.
- Release waivers and termination pay · Which rate a split contract pays at release
- trade himBLOCKED
- Not now: players on major-league contracts cannot be traded after the Aug 3 deadline until the day after the World Series.
- Trade deadline · 10-and-5 rights · June 15 no-trade for free-agent signees
- renew him for next year
- Pre-arbitration: the club sets his 2027 salary near the minimum ($780,000 floor) and he has no leverage beyond a non-tender.
- Minimum salaries · Tender deadline
What the rules say about him
- Option years and the 20-day rule1 option year left entering 2026.A season with fewer than 20 days on optional assignment does not count as an option year, and those days count as Major League service. 2022-2026 Basic Agreement, Article XIX(E) and XXI(B), p. 98 (the number itself is in Major League Rule 7(c))
- Five optional assignments per seasonOptioned 0 times this season that count toward the cap of 5: 5 left.A player can be optioned at most five times in a season; a sixth trip requires outright waivers. 2022-2026 Basic Agreement, Article XIX(E), p. 98 (the number itself is in Major League Rule 7(c))
- 60-day IL and the November crunchOn the 60-day IL: not counting against the 40-man now, but must be reinstated by Nov 5 (5th day after the World Series).A player on the 60-day IL is off the 40-man, but every 60-day IL player must be reinstated after the World Series, healthy or not. 2022-2026 Basic Agreement, Article XIII(C), p. 56 (the number itself is in Major League Rule 2)
- Injured players cannot be sent downOn the Major League injured list: cannot be optioned or outrighted until he is healthy and reinstated, so an injured fringe player keeps his roster spot by default.No assignment to a minor-league club while a player is on a Major League injured list, and an injured player who cannot play cannot be optioned or outrighted. 2022-2026 Basic Agreement, Article XIX(C)(1)-(2), p. 96
- Post-season roster eligibilityOn the 60-day IL before the cutoff, so he is on the eligibility list. He has served the 60 days (173), so the only step is reinstatement: the club must open a 40-man spot and a 26-man spot before the series roster is submitted.The post-season eligibility list is fixed at noon ET on September 1: everyone on the 40-man, the 60-day IL or the military list at that moment, who then stays there without interruption. 2022-2026 Basic Agreement, Attachment 25, p. 253 (the number itself is in Major League Rule 40)
- Rule 5 clockOn a 40-man roster (would first be exposed after 2025 otherwise).
