What's at stake

Which team wins, the margin of victory, and whether total runs exceed 9.5 determine payouts for the moneyline, spread, and total markets.

The game result sets official settlements and affects season records and fantasy outcomes; resolution follows the MLB box score after nine innings or extra innings as played.

Who's in play

Starting pitchers and both bullpens are the primary individual players who determine outcome probabilities.

Everyday hitters, platoon lineups, managers' pinch‑hit and relief choices, and umpires' strike zone influence scoring, margins, and the total.

What drives it

Probable starters' recent form, pitch counts, and days of rest move the lines before first pitch.

Weather, ballpark factors, matchup splits, late scratches, and reported injuries also change live spreads and the expected total.

What to watch

Lineups and the official starting pitchers announced about an hour before first pitch will confirm platoon edges.

Key signals: final weather radar, bullpen warmups, in-game pitch counts, late scratches before first pitch, and 6th–9th inning bullpen usage that often decides spread outcomes.
