Three wagers resolve on the final box score: which team wins (moneyline), whether Kansas City wins by two or more runs (Royals -1.5 spread), and whether combined runs exceed 8.5 (over/under).
Settlement follows the official final score, including extra innings; suspended or canceled games follow league and market rules.
Starting pitchers and bullpen depth shape the game's immediate course. Handedness, pitch counts, recent form, and scheduled relievers set early run-scoring expectations.
Kansas City's lineup, Detroit's hitters, managers' matchup choices, and any late scratches decide late scoring and whether the Royals cover -1.5.
Weather and the ballpark alter the run environment: wind direction, temperature, and humidity change fly-ball carry and scoring probability.
Umpires' strike zone, bullpen matchups, in-game injuries, and managerial pinch-hit decisions swing scoring; public betting and last-minute lineup changes also move odds.
First pitch and the announced starters are immediate market movers; a bullpen game or a late scratch can flip moneyline and spread probabilities.
Watch lineup releases, weather radar through first pitch, inning-by-inning scoring, pitcher exit times, and official injury reports up to and during the game.
