Key catalysts include roster changes such as injuries to star position players or pitchers on either team, which affect run-scoring potential and game pace. Weather conditions—wind direction, temperature, and humidity—influence ball carry and scoring likelihood. Bullpen availability and recent form matter significantly, since tired or depleted relief corps may affect late-inning dynamics. Lineup announcements, particularly whether teams deploy offensive or defensive strategies, can shift probabilities. Late-breaking news about player health, umpire assignments, or venue factors will move trader positioning as game time approaches and new information becomes public.
