What's at stake

A single regular-season game settles multiple bets: moneyline, run-line margins (-1.5 through -4.5), and five totals thresholds between 8.5 and 12.5.

Payouts depend on the final score and margin after nine innings, with extra innings applying if the game goes beyond regulation.

Who's in play

Starting pitchers for Baltimore and New York largely determine run totals and the moneyline.

Relievers, closers, the two lineups' power hitters, and each manager's bullpen decisions control late-inning scoring and run-line resolution.

What drives it

Pitching matchups — starter handedness, recent ERA, strikeout rates, and first-inning effectiveness — shift totals and margin probabilities.

Weather, Yankee Stadium's homer-friendly dimensions, bullpen workloads, injuries, and lineup changes produce short-term market moves.

What to watch

Before first pitch, confirm announced starters, the batting orders, and any late scratches or bullpen-recall reports.

Also monitor weather updates, in-game pitch counts, early scoring through the third and fifth innings, and closer warmups for late-line moves.
