The case for St. Louis Cardinals
Starting pitcher edge: 8 points
LyDia gives Gordon Graceffo a 8-point edge over Trevor Rogers, driven mainly by ERA (2.98 vs 4.38) and WHIP (1.07 vs 1.25).
Bats are hot: +0.009 wOBA
St. Louis Cardinals 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 Baltimore Orioles
Late-inning bullpen advantage
St. Louis Cardinals relievers have a 9.24 ERA over the last 7 days; Baltimore Orioles relievers have a 0.45. If this is still close after six innings, that gap favors Baltimore Orioles.
Their bats are hot: +0.008 wOBA
Baltimore Orioles is outhitting its own season form over the last 15 days.
Team strength favors Baltimore Orioles
Before any pitcher or bullpen adjustment, LyDia's own team-strength model has Baltimore Orioles ahead (49.3% to 42.6%). The pick still comes from St. Louis Cardinals once the pitcher and bullpen terms are applied.
Why it is not official
Below the 61.0% official gate
Win probability is 50.6%. 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.
Setup quality below the bar
Lab Rating is 4.3/10, under the 7.2/10 required for an official pick.
Own bullpen carries risk: 7.8/10
The St. Louis Cardinals bullpen comes in tired. A lead after six innings is less safe than usual.
Why the setup score is what it is
Conviction: 0/10
LyDia's own win probability for St. Louis Cardinals (50.6%) is close enough to a coin flip that the rating credits little or no conviction -- credit only starts above 55%.
Pitching plan: 18/30
Gordon Graceffo rates 71 on LyDia'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.
Bullpen: 1.11/10
LyDia does not see a meaningful bullpen edge for St. Louis Cardinals here.
Offense: 24.06/50
St. Louis Cardinals's recent form does not clearly outpace Baltimore Orioles's.
Why the price is what it is
Team strength: 42.6%
Before any pitcher or bullpen adjustment, LyDia's team-strength model alone makes St. Louis Cardinals 42.6% to win. Everything below moves the price from this starting point.
Pitcher score gap: 3 points
The pitcher-score gap favors St. Louis Cardinals by 3 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: -0.105
The bullpen-fatigue gap between the two pens nudges the price toward Baltimore Orioles. This moves the price less than the starting pitchers do, since a starter covers more of the game than the bullpen.
Net effect: 42.6% -> 50.6%
Team strength alone had St. Louis Cardinals at 42.6%. After the pitcher and bullpen terms, the price is 50.6% -- the same number shown as Model Lean above.

Final result
Orioles 5, Cardinals 7
How the analysis held up
St. Louis Cardinals won, the side LyDia's model favored.
LyDia's two internal reads disagreed pregame by 41.5 points — the team-strength model favored St. Louis Cardinals, the run-projection model favored Baltimore Orioles. The team-strength model had the winner here.
Gordon Graceffo (St. Louis Cardinals), the starter LyDia's pitcher score favored, actually outpitched Trevor Rogers: 3.0 IP, 0 ER (0.00 ERA) against 5.0 IP, 6 ER (10.80 ERA). The edge held up.
The St. Louis Cardinals bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 5 earned runs over 6.0 innings (7.50 ERA) — the risk read showed up.
Baltimore Orioles scored 5, 1.8 fewer than the 6.8 pregame projection.
St. Louis Cardinals scored 7, 4.2 more than the 2.8 pregame projection.
