Several catalysts could shift odds before the game begins. Lineup announcements, particularly the identity of starting pitchers, carry significant weight—dominant starters typically lower first-inning scoring expectations. Weather conditions, field dimensions, and recent team performance trends also influence trader positioning. Injury reports affecting key hitters or pitchers can trigger sharp repricing. As game time nears, any last-minute roster changes or weather delays may prompt final adjustments. Once the first pitch is thrown, live action becomes the dominant driver until the inning concludes.
