Description

This event tracks individual player performance in a specific baseball game, focusing on achieving certain thresholds of total bases. Each market corresponds to a different player and a specific total bases requirement they need to meet or exceed during the game.

Kalshi

All markets resolve based on whether specified players record a designated number of total bases (ranging from 2 to 5+) in the Arizona vs Boston game scheduled for August 18, 2026. If a player is scratched, not in the starting lineup, or fails to record a plate appearance, the market resolves to the fair market price. If a player enters the game as a substitute without starting, the market also resolves to the fair market price, with pinch-hit at-bats excluded from consideration. Only players who start and record at least one plate appearance contribute to the market outcome, which is determined solely by their total bases accumulated during the game.
