Janson Junk is a Miami Marlins SP projected for 187 fantasy points on 129.1 IP, 94 K, 4.2 ERA, 1.295 WHIP by the managr projection engine. Monte-Carlo outcome odds put an elite season at 0% and a bust at 15%.
Projection snapshot: 2026-09-28. Rebuilt daily.
Janson Junk's 2026 projection is built on 129 innings as a starter.
Across 2 seasons with meaningful innings, Junk's biggest strikeout year came in 2026 at age 30: 89 strikeouts over 124 innings, with 6 wins. Innings across 2025 and 2026 ran 110 and 124.
In 2026, Junk's 4.22 ERA sat close to a 4.21 expected ERA, so the runs allowed matched the quality of contact.
Tracking data from 2026: Junk struck out 17.0% of batters and walked 6.3%, a strikeout-minus-walk rate of 10.7 points, and hitters missed on 15.9% of their swings. Contact against Junk averaged 89.8 mph off the bat, with a 7.3% barrel rate.
Junk's projected range runs from a 178-point floor to a 370-point upside, around a 187-point median: a spread of 192 points, or 103% of the median.
By statistical profile, the closest comparisons to Junk on the board are Anthony Kay, Grant Holmes and Kyle Leahy.
At 30, Junk 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.
