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

The plan keeps him: late-inning relief · 59 IP · 0.5 WAR in the role.

Options left: unknown (Keystone can’t estimate it from public data).

2027 starter hook and bullpen rolesdue Spring training · medium confidence
Rotation (Winter Plan): Paul Skenes, Jared Jones, Braxton Ashcraft, Bubba Chandler and Mitch Keller. Two times through for Mitch Keller once his medicals clear. Let Braxton Ashcraft face the order a third time (a toss-up). Let Paul Skenes face it too, pending the review of his velocity drop. Jared Jones: a 22-batter leash (about 81 pitches) after his arm injury, not an open third time; past it, decide by matchup (a toss-up). Give Bubba Chandler development innings on a 22-batter leash (about 82 pitches), once through the top of the order a third time, at about 1.0 ± 1.2 runs against a two-times-through hook (a toss-up); the goal is first two passes at .306 xwOBA or better, not a third-time skill, pending the review of his velocity drop. Ladder: Mason Montgomery and Yohan Ramírez in the late innings (within noise of each other); Evan Sisk and Luke Weaver setting up (within noise of each other). Move Evan Sisk into the leverage ladder. Move Isaac Mattson out of it.

Plan for 2027

1
Command medium ask Command first: start with the curveball
Location 79 (3rd percentile) in 2026 with a 12.2% walk rate over 362 batters (MLB median 8.6%). His curveball grades 70 on location and lands in the zone 37% of the time (MLB curveballs: 40%). With no plan, a walk rate like his tends to come back toward the median on its own (about 10.6% next year); the target, 9.1%, is the more ambitious of a realistic one-year step (the median, his own best season on today’s league basis, or a big one-year gain) and what a quarter of similar pitchers beat with no plan.
Walk rate: 12.2% target 9.1% no plan ≈ 10.6% Check after about 411 batters faced (more than his 2026 total) · noise then ±1.6% Keystone Location

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
