What the Winter Plan does with Jebb: its decisions feed, the dated moves and the briefs

Rule 5 eligible; the plan leaves him unprotected on Nov 17.

Rule 5 pick risk 0.17 (the plan’s ordering, not a probability); expected loss if exposed 0.04 WAR.

  • Rule 5 protectiondue Nov 17 · medium confidence

    Protect Termarr Johnson (2B, AAA, FV 45), Derek Diamond (SIRP, AAA, FV 40) and Keiner Delgado (SS, AA, FV 40) by Nov 17. Expose the rest; the most likely to be taken is Cy Nielson (AAA, risk 0.23; expected loss 0.03 long-term WAR, below the 0.06 that cutting Noah Murdock for a fourth spot would cost; the plan's rule protects at most three).

Plan for 2027

    He chases more often than 72% of Triple-A hitters (150+ PA): the 72nd percentile for chasing. The player page’s tracking bar ranks the other way (higher is better). The target beats regression to the mean: it is his expected next season with no plan (a value this far from the Triple-A median tends to come back part of the way) plus the step a quarter of similar players beat. At 24, he’s about 3 years younger than the typical Triple-A player, so the level median is a high bar.

    Chase rate: 31% target 27% no plan ≈ 30% No one-season check: a lean. Telling this target from noise takes about 731 pitches out of the zone; he had 462 in 2026. Triple-A tracking

Each goal is checked when his sample can tell the target from noise: the 2027 All-Star break if it can by then, else season’s end or the sample it needs; if no single season can, it’s a lean. Coach card
