2026-09-23, 7:40 PM ET, Kauffman Stadium. Bryan Hudson (L) against Seth Lugo (R). Every number derives from the public Statcast store and the engine's published boards. Charts are code-drawn. Probabilities, not picks. Statcast through 2026-09-22.

What decides tonight

Every number below is a probability this engine published before first pitch and grades that night, or a plain count. No scouting verdicts are ranked here — those live in the panels and carry their own sample sizes.

Seth Lugo (RHP)

2787 pitches, K% 18% vs LHB (460 BF) / 17% vs RHB (273 BF)

31 apps · median 24 BF · reaches the order 3.0× (max 4) · exits at 92 pitches (IQR 88–94, 31 starts) · fastball +0.2 mph late (19 deep starts). Fade is measured inside each start on nights that reached 85 pitches, so it is not flattered by the short outings.

RV/100 is run value per 100 pitches from the pitcher's side, so negative is good (a curveball at −1.3 costs the pitcher runs even if it misses bats — a real tension worth reading, not a contradiction). Whiff, chase and xwOBA are computed on this pitcher's own pitches this season; low-usage pitches carry small samples.

  • Hunt the sinker early: 21% of his first pitches, only 11% whiffs, 64% in-zone on 0-0.
  • Two strikes: expect the cutter (22% of 2-strike pitches vs 16% overall).

Bryan Hudson (LHP)

1019 pitches, K% 22% overall (270 BF; split withheld, short side only 108 BF)

Opener usage: in a typical outing he does not get through the order once (67 appearances, median 4 batters). Prep the second and third look against the bullpen, not this arsenal — see Bullpens.

White Sox bats vs Seth Lugo

Season quality vs tonight's starter hand, percentile-colored vs league: red elite, paper average, blue poor. P columns are the engine's published board numbers for this game. Batting order as posted. 30d contact is the last-30-day contact rate minus the season rate; an arrow is drawn only when the move clears two standard errors of its own noise, and n is the recent swing count.

Kansas City Royals hitters, one card each

One card per hitter: the published probabilities this engine grades tonight, his whiff shape by pitch group, and his season against this starter's hand with the sample stated. Times-through-order and leverage splits are deliberately absent — at a median 45 plate appearances the third-time-through number carries a standard error roughly three times the effect it would be claiming.

Matchups: CWS hitters vs Seth Lugo

Where this starter's actual usage meets each hitter's measured holes and damage, on the same map. An edge is only reported where the pitcher genuinely goes — a hole against a pitch he does not throw is not a matchup — and only where the rate is measurably worse than league for a typical hitter in that same spot. Every line carries its sample size. Batter-versus-pitcher history is shown as trivia and is not used in any of it: the samples that actually occur are far too small to support a conclusion, and most public matchup content is built on them anyway.

1. Sam Antonacci

Edge: batterWhen the ball goes up and away — and he puts 7% of his pitches there — the batter does real damage: 0.401 expected value per ball in play, against a 0.273 league average in that spot. (21 balls in play.)

Kansas City Royals: the running game and the defense

Sprint speed says who can run; attempt rate says who will. Rate is steals of second per time on first, shrunk toward the league’s 5.3% at 22 opportunities, with the raw count beside it. Verdict needs 15+ times on first. Sprint speed and Outs Above Average are Baseball Savant leaderboard metrics — measured from tracking data we do not have and did not compute.

Behind the plate: Kyle Teel — runners went 49-for-62 against him (21% caught). That is mostly the pitcher: measured split-half reliability for a catcher’s own caught-stealing rate is +0.59, and the spread between catchers is smaller than the sampling noise. Read it as what happened, not as a rating.
