Pushing the cut risk around: roster status (2) raises it, last season's WAR (-0.74) raises it, share of appearances as a starter (1) lowers it.

Context the model does not weigh: ZiPS projects 0.6 WAR, 0.2 WAR this season; 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?

LAA 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 7th among the returners (-0.1 WAR against a bar of -0.3), which the calibrated model turns into 80% kept through the tender deadline. Ranked by ZiPS and Steamer instead, which credit his longer track record, he is 6th (0.4 WAR, bar 0.2), 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 (99), so the only step is reinstatement: the club must open a 40-man spot (the 40-man is full, so someone must be traded, outrighted, released or moved to the 60-day IL) 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 (1 yr, $800k (2026)). 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.

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.
