Pushing the cut risk up: this season's WAR (-0.01) raises it, age (30.55) raises it, prior DFAs (3) raises it.
Context the model does not weigh: ZiPS projects 0.9 WAR, -0.0 WAR this season; 15 OF 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?
DET returns 12 IF on the 40-man once 1 free agent leaves; about 8 IF jobs survive a normal winter. By his own recent record he ranks 11th among the returners (-0.6 WAR against a bar of 0.2), which the calibrated model turns into 18% kept through the tender deadline. Ranked by ZiPS and Steamer instead, which credit his longer track record, he is 9th (0.4 WAR, bar 0.5), worth 25% 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: Post-season eligible
On the 40-man before noon ET Sep 1. He stays eligible as long as he remains on the 40-man or 60-day IL through the post-season; an outright after the cutoff would end automatic eligibility.
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 minors
- Yes, 1 option year left. 4 of the five optional assignments for 2026 remain. He has 15 option days this season; at 20 a 2026 option year is used and those days stop counting as service. Once down he must stay 10 days unless he replaces an injured or traded player. An option does not trigger his Article XX-D right; only an outright would.
- Option years and the 20-day rule · Five optional assignments per season · Minimum stay on option
- 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. He was outrighted before (3x) give him the Article XX-D choice: elect free agency immediately (giving up the rest of his salary) or accept the assignment, keep getting paid, and elect free agency after the season unless he is added back to a 40-man first. 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.
- 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; only 15 option days this season (under 20, so none used).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 1 time this season that count toward the cap of 5: 4 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))
- Article XX-D: the right to walkOutrighted before (Oct 2025): a second outright lets him elect free agency, so he cannot be stashed in the minors against his will.A player with three or more years of service (or a Super Two), or any player being outrighted for the second time in his career, may elect free agency instead of accepting the outright. 2022-2026 Basic Agreement, Article XX(D)(1)-(2), (4), p. 110
- Option years and the 20-day ruleCurrently optioned with 15 days this season: 5 more and a 2026 option year is used.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))
- Post-season roster eligibilityOn the 40-man before noon ET Sep 1. He stays eligible as long as he remains on the 40-man or 60-day IL through the post-season; an outright after the cutoff would end automatic eligibility.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)
