Cooper Criswell is a Seattle Mariners RP projected for 79 fantasy points on 42.6 IP, 33 K, 3.3 ERA, 1.399 WHIP, 1 SV by the managr projection engine. Monte-Carlo outcome odds put an elite season at 0% and a bust at 17%.
Projection snapshot: 2026-10-18. Rebuilt daily.
Cooper Criswell's 2026 projection is built on 43 innings out of the bullpen.
Across 3 seasons with meaningful innings, Criswell's biggest strikeout year came in 2024 at age 27: 73 strikeouts over 99 innings, with 6 wins. Innings across 2023, 2024 and 2026 ran 33, 99 and 41, a drop in workload worth weighing against the forecast.
In 2026, Criswell's 3.32 ERA came in below a 3.81 expected ERA. Expected ERA is built from the quality of contact allowed rather than the runs that scored, so fewer runs crossed than that contact would usually produce.
Tracking data from 2026: Criswell struck out 18.0% of batters and walked 9.3%, a strikeout-minus-walk rate of 8.7 points, and hitters missed on 20.7% of their swings. Contact against Criswell averaged 86.9 mph off the bat, with a 4.8% barrel rate.
Criswell's projected range runs from a 75-point floor to a 127-point upside, around a 79-point median: a spread of 52 points, or 66% of the median.
By statistical profile, the closest comparisons to Criswell on the board are Colin Holderman, Nate Pearson and JoJo Romero.
At 29, Criswell is in the age range where pitchers typically hold their skills, and the multi-year valuation applies little age adjustment.

Final Value = Raw Projection × MasterConfidence × TeamContext. Each layer answers one question - no overlap.
Recency weighting: prior seasons contribute by recency (more recent = more weight) and sample size (more PA = more weight).
Shrinkage: observed rates regress toward position-specific population means by an amount inversely proportional to sample size. Catches small-sample outliers.
Quality-of-contact adjustments: xwOBA, barrel rate, and bat-tracking metrics replace luck-driven outcome stats with skill-driven ones.
PT modeling: projected PA is anchored to workload tier (full-time, regular, platoon, backup catcher) using historical role distributions.
Monte Carlo: N simulated seasons per player using projected mean + uncertainty, producing P10 / P50 / P90 distribution and bust%.
Confidence layers: four orthogonal multipliers: Roster (depth chart), Role (PT certainty), Sample (career PA), Market (consensus alignment). The Audit tab shows all four for every player.
VAR: Value Above Replacement at the player's primary position. Replacement levels are floored per position so SS scarcity doesn't artificially inflate stable middle infielders.
