Pushing the cut risk around: age (34.39) raises it, prior DFAs (2) raises it, DFAs in the last year (1) raises it.

Context the model does not weigh: ZiPS projects 0.5 WAR, 0.1 WAR this season; 18 RP on the 40-man, of whom Tyler Alexander, Trevor Williams, Jordan Montgomery, Jalen Beeks are headed to free agency.

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?

TEX returns 14 RP on the 40-man once 4 free agents leave; about 9 RP jobs survive a normal winter. By his own recent record he ranks 15th among the returners (1.6 WAR against a bar of -0.1), which the calibrated model turns into 100% kept through the tender deadline. Ranked by ZiPS and Steamer instead, which credit his longer track record, he is 15th (0.3 WAR, bar 0.2), worth 100% 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: Injury replacement only

Added to the 40-man on Sep 1, after the Sep 1 noon cutoff, so he is not automatically eligible. He was not in the organization before the cutoff, so he cannot be added to a post-season roster this year.

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 without his consent: with five years of service he can refuse the assignment or elect free agency instead. The club's only unilateral moves are to keep him, trade him, or release him.
Article XIX-A: five years, no forced assignment
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, $112.62k (2026); $780k, prorated). If he clears, he cannot be outrighted without his consent: he can refuse and force a release with his contract intact, or elect free agency (forfeiting termination pay).
Designated for assignment: 7 days · Outright waivers · Article XIX-A: five years, no forced outright
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
Let the season end
He becomes an Article XX-B free agent at 9 AM ET the day after the World Series; only the club can talk to him for five days after that. A qualifying offer is possible only if he has been with the club since Opening Day and never received one before.
