Final result
White Sox 4, Royals 5
How the analysis held up
Kansas City Royals won. Leo's model favored the other side.
Leo's two internal reads disagreed pregame by 20.7 points — the team-strength model favored Chicago White Sox, the run-projection model favored Kansas City Royals. The run-projection model had the winner here.
Seth Lugo (No clear pitching-plan edge), the starter Leo's pitcher score favored, actually outpitched Bryan Hudson: 3.1 IP, 4 ER (10.80 ERA) against 0.1 IP, 3 ER (81.00 ERA). The edge held up. Neither starter actually pitched well tonight, though — this is a smaller-of-two-bads comparison, not a starter who dealt.
The Chicago White Sox bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 1 earned run over 7.2 innings (1.17 ERA) — the risk read did not show up on the scoreboard tonight. Note: 1 of the runs charged to the Chicago White Sox pitching staff overall was unearned — not something the bullpen's stuff should be blamed for.
The Kansas City Royals bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 0 earned runs over 5.2 innings (0.00 ERA) — the risk read did not show up on the scoreboard tonight.
Likely driver: Bryan Hudson, the pick's own starter, was rocked for a 81.00 ERA, and the Kansas City Royals bullpen quietly shut the game down (0.00 ERA over 5.2 innings).

Pitching plan edge: Leo gives Seth Lugo the edge over the Chicago White Sox pitching plan. Bryan Hudson is projected for only 1 innings, with the Chicago White Sox bullpen covering the rest -- this compares Seth Lugo's own line against the Chicago White Sox blended starting-pitcher-and-bullpen quality, not two starters directly.
Blended read: For the Chicago White Sox, the bullpen is projected to throw more of the game than Bryan Hudson (about 1 innings for the starter), so Leo grades that side on a whole-game effective ERA of 4.98 rather than Bryan Hudson's own 3.43. Whole-game, that is 4.73 for the Kansas City Royals against 4.98 on the other side, so the blended read leans Kansas City Royals.

Bullpen matchup
Full Bullpen Fatigue Index →Risk is what the model actually uses: fatigue blended with how well the pen has pitched. High fatigue with high efficiency is a tired pen that is still getting outs.
| Metric | White Sox | Royals |
|---|---|---|
| Fatigue | 7.0/10, Tired | 5.8/10, Normal |
| Efficiency | 3.2/10, Below average | 2.4/10, Struggling |
| Combined risk | 7.9/10, Tired | 7.1/10, Tired |
| Relief innings, last 7 days | 26.0 | 20.7 |
| Back-to-back arms | 3 | 5 |
| 7-day ERA | 6.23 | 7.40 |
| 7-day WHIP | 1.69 | 1.74 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
