The case for Houston Astros

Starting pitcher edge: 34 points
LyDia gives Hunter Brown a 34-point edge over Carson Whisenhunt, driven mainly by ERA (3.53 vs 7.25) and WHIP (1.24 vs 1.84).
Late-inning bullpen advantage
San Francisco Giants relievers have a 6.26 ERA over the last 7 days; Houston Astros relievers have a 1.77. If this is still close after six innings, that gap favors Houston Astros.
Bats are hot: +0.022 wOBA
Houston Astros is outhitting its own season form over the last 15 days. Recent form is context, not a model input, but it points the same way here.

The case for San Francisco Giants

The case is thin
The model finds little going San Francisco Giants's way — it trails on the pitching plan, bullpen, and recent form. The main path to a San Francisco Giants win is variance.

Why it is not official

Below the 61.0% official gate
Win probability is 59.0%. LyDia does not make a game official below 61.0%, no matter how good the price is. This is a value spot, not a high-confidence winner.
The verdict Worth monitoring, nothing more. The setup has pieces but does not add up to a bet at today's price.

Houston Astros remains on the watchlist. Lab Rating 8.2/10: conviction 18.1, pitching plan 20, bullpen 19.17, offense 25. LyDia projects 59.0% against a 62.7% no-vig market number, a -3.8% model edge at -177. Houston Astros owns the starting pitcher edge by 34 points. Bullpen read: Supports LyDia side. Houston Astros's pen efficiency: Effective (7.4/10). Pitching plan: Carson Whisenhunt 4.5 IP + remaining bullpen 4.5 IP. Bullpen fatigue, efficiency, and combined risk grade only the innings assigned to the bullpen.

Pitcher edge: LyDia gives Hunter Brown a 34-point edge over Carson Whisenhunt, driven mainly by ERA (3.53 vs 7.25) and WHIP (1.24 vs 1.84).

How to read this: the scorecards above name the starters; every number lives in this table. Highlighted cells mark a gap big enough to matter. K% and BB% are strikeout and walk rate as a share of batters faced -- K-BB% is the two combined into one skill number. HR/9 is home runs allowed per nine innings. Ground-ball and fly-ball rate are neither good nor bad on their own: high ground-ball pitchers trade strikeouts for double plays and fewer home runs, and on this data source the two rates are complementary (they add to 100%), not independent reads.

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.
