Tonight's game settles six separate wagers: the final winner, the full-game total (over/under 9.5), the full-game spread (-1.5), whether any run scores in the 1st inning, the first-5 innings spread (-2.5), and the first-5 innings total (over/under 4.5).

Payout and settlement rules differ by market; some resolve after five innings, others after the final out.

Starting pitchers, the opposing top-of-order hitters, and each team's bullpen are the primary actors on these markets.

Managers' lineup choices, pinch-hitters, and matchup decisions matter too. Umpires and park factors also influence run environment and the likelihood of early-inning scoring.

Bullpens' usage and how deep the starters go set the chances for late runs and whether spreads survive to the final inning.

Weather, home-park run tendencies, platoon splits, and lineup health shift totals and first-inning outcomes quickly if a key bat or arm is scratched.

Game-time decisions on the starter, official lineup releases, and any scratches will move prices before the first pitch.

Early signals include runs or hits in the first inning, starter pitch counts and hook timing, bullpen warmups, and the score through five innings; monitor weather and late scratches for sudden volatility.
