Kyle Leahy is a St. Louis Cardinals SP+RP projected for 273 fantasy points on 147.9 IP, 139 K, 3.7 ERA, 1.344 WHIP by the managr projection engine. Monte-Carlo outcome odds put an elite season at 0% and a bust at 14%.
Projection snapshot: 2026-09-28. Rebuilt daily.
Kyle Leahy's 2026 projection is built on 148 innings as a full-time starter.
Across 3 seasons with meaningful innings, Leahy's biggest strikeout year came in 2026 at age 29: 132 strikeouts over 140 innings, with 10 wins. Innings across 2024, 2025 and 2026 ran 49, 88 and 140, a rising workload.
In 2026, Leahy's 3.66 ERA came in below a 4.89 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: Leahy struck out 22.1% of batters and walked 6.9%, a strikeout-minus-walk rate of 15.2 points, and hitters missed on 22.7% of their swings. Contact against Leahy averaged 91.0 mph off the bat, with a 9.8% barrel rate.
Recent pitch tracking flags Leahy's arsenal as trending up. Over the last 191 pitches, the whiff rate sits 1 point below and the called-strike-plus-whiff rate sits 4 points above Leahy's own baseline. The engine applies a +4% adjustment to the rest-of-season projection for a move this size; the full-season projection is untouched.
Leahy's projected range runs from a 260-point floor to a 437-point upside, around a 273-point median: a spread of 177 points, or 65% of the median.
By statistical profile, the closest comparisons to Leahy on the board are Anthony Kay, Janson Junk and Colin Rea.
At 29, Leahy 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.
