The case for Toronto Blue Jays

Starting pitcher edge: 11 points
LyDia gives Dylan Cease a 11-point edge over Emerson Hancock, driven mainly by K/9 (13.0 vs 8.2) and K-BB% (25.3% vs 16.6%).
Bats are hot: +0.015 wOBA
Toronto Blue Jays 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 Seattle Mariners

Late-inning bullpen advantage
Toronto Blue Jays relievers have a 5.17 ERA over the last 7 days; Seattle Mariners relievers have a 6.35. If this is still close after six innings, that gap favors Seattle Mariners.
Team strength favors Seattle Mariners
Before any pitcher or bullpen adjustment, LyDia's own team-strength model has Seattle Mariners ahead (47.7% to 43.0%). The pick still comes from Toronto Blue Jays once the pitcher and bullpen terms are applied.

Why it is not official

Setup quality below the bar
Lab Rating is 6.4/10, under the 7.2/10 required for an official pick.
Own bullpen carries risk: 10.0/10
The Toronto Blue Jays bullpen comes in high risk. A lead after six innings is less safe than usual.

Why the setup score is what it is

Conviction: 3.17/10
LyDia leans toward Toronto Blue Jays, but not strongly enough to earn full conviction credit.
Pitching plan: 30/30
Dylan Cease rates 82 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: 2.51/10
LyDia does not see a meaningful bullpen edge for Toronto Blue Jays here.
Offense: 28.69/50
Toronto Blue Jays's recent offensive form clearly outpaces Seattle Mariners's over the tracked windows.

Why the price is what it is

Team strength: 43.0%
Before any pitcher or bullpen adjustment, LyDia's team-strength model alone makes Toronto Blue Jays 43.0% to win. Everything below moves the price from this starting point.
Pitcher score gap: 9 points
The pitcher-score gap favors Toronto Blue Jays by 9 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: -0.09
The bullpen-fatigue gap between the two pens nudges the price toward Seattle Mariners. This moves the price less than the starting pitchers do, since a starter covers more of the game than the bullpen.
Net effect: 43.0% -> 61.4%
Team strength alone had Toronto Blue Jays at 43.0%. After the pitcher and bullpen terms, the price is 61.4% -- the same number shown as Model Lean above.

How the analysis held up

Toronto Blue Jays won, the side LyDia's model favored.

Dylan Cease (Toronto Blue Jays), the starter LyDia's pitcher score favored, actually outpitched Emerson Hancock: 6.0 IP, 1 ER (1.50 ERA) against 5.0 IP, 5 ER (9.00 ERA). The edge held up.

The Seattle Mariners bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 3 earned runs over 3.0 innings (9.00 ERA) — the risk read showed up.

The Toronto Blue Jays bullpen was flagged as elevated risk pregame (High risk). In relief it actually allowed 0 earned runs over 3.0 innings (0.00 ERA) — the risk read did not show up on the scoreboard tonight.

Toronto Blue Jays scored 8, 5.5 more than the 2.5 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.
