Several catalysts can shift odds before the game begins. Lineup announcements, particularly the starting pitchers or key offensive players, often trigger sharp moves. Injury reports or last-minute roster changes can significantly alter expectations about run-scoring potential.

Recent team performance, bullpen availability, and head-to-head matchup history also influence trader positioning. Real-time updates during pre-game coverage may prompt final adjustments as game time approaches.
