Seranthony Domínguez is a Seattle Mariners RP projected for 198 fantasy points on 66.6 IP, 71 K, 3.6 ERA, 1.250 WHIP, 12 SV by the managr projection engine. Monte-Carlo outcome odds put an elite season at 0% and a bust at 15%.
Projection snapshot: 2026-10-18. Rebuilt daily.
Seranthony Domínguez's 2026 projection is built on 67 innings as a closer. That role carries 12 projected saves.
Across 7 seasons with meaningful innings, Domínguez's biggest strikeout year came in 2025 at age 30: 79 strikeouts over 63 innings, with 4 wins. Innings across 2024, 2025 and 2026 ran 59, 63 and 62.
In 2026, Domínguez's 3.63 ERA sat close to a 3.65 expected ERA, so the runs allowed matched the quality of contact.
Tracking data from 2026: Domínguez struck out 25.0% of batters and walked 11.9%, a strikeout-minus-walk rate of 13.1 points, and hitters missed on 27.9% of their swings. Contact against Domínguez averaged 87.1 mph off the bat, with a 6.9% barrel rate.
Domínguez's projected range runs from a 188-point floor to a 392-point upside, around a 198-point median: a spread of 204 points, or 103% of the median.
By statistical profile, the closest comparisons to Domínguez on the board are Steven Okert, Josh Hader and Tyler Wells.
At 31, Domínguez is at the age where velocity and durability become the leading risks for pitchers, and the multi-year valuation discounts later seasons accordingly.

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.
