The case for San Diego Padres

Bats are hot: +0.016 wOBA
San Diego Padres 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

Their bats are hot: +0.011 wOBA
San Francisco Giants is outhitting its own season form over the last 15 days.

Why it is not official

Setup quality below the bar
Lab Rating is 5.9/10, under the 7.2/10 required for an official pick.
Own bullpen carries risk: 7.6/10
The San Diego Padres bullpen comes in tired. A lead after six innings is less safe than usual.

Why the setup score is what it is

Conviction: 3.13/10
Leo leans toward San Diego Padres, but not strongly enough to earn full conviction credit.
Pitching plan: 30.67/40
Nick Pivetta rates 72 on Leo's pitcher score, judged on its own merits (50-80 is the credited range). That is a strong start on its own, and it earns most or all of the available credit here.
Offense: 25.44/50
San Diego Padres's recent offensive form clearly outpaces San Francisco Giants's over the tracked windows.

Why the price is what it is

Team strength: 54.6%
Before any pitcher or bullpen adjustment, Leo's team-strength model alone makes San Diego Padres 54.6% to win. Everything below moves the price from this starting point.
Pitcher score gap: 6 points
The pitcher-score gap favors San Diego Padres by 6 points. This is the biggest single mover of the price -- a large gap moves it a lot, a small gap barely moves it.
Bullpen adjustment: -0.03
The bullpen-fatigue gap between the two pens nudges the price toward San Francisco Giants. This moves the price less than the starting pitchers do, since a starter covers more of the game than the bullpen.
Net effect: 54.6% -> 61.3%
Team strength alone had San Diego Padres at 54.6%. After the pitcher and bullpen terms, the price is 61.3% -- the same number shown as Model Lean above.
The verdict Leo passes. The combined Lab Rating did not clear the official threshold.

Final result

Padres 6, Giants 4

How the analysis held up

San Diego Padres won, the side Leo's model favored.

Leo's two internal reads disagreed pregame by 36.5 points — the team-strength model favored San Diego Padres, the run-projection model favored San Francisco Giants. The team-strength model had the winner here.

Nick Pivetta (San Diego Padres), the starter Leo's pitcher score favored, actually outpitched Logan Webb: 4.0 IP, 2 ER (4.50 ERA) against 5.0 IP, 6 ER (10.80 ERA). The edge held up.

The San Diego Padres bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 2 earned runs over 5.0 innings (3.60 ERA) — the risk read did not show up on the scoreboard tonight.

The San Francisco Giants bullpen was not flagged pregame, but it had a night worth noting: 0 earned runs allowed over 4.0 relief innings (0.00 ERA) — quietly better than the pregame read implied.

San Diego Padres scored 6, 2.7 more than the 3.3 pregame projection.

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.
