Detroit vs San Diego: Total Bases

It measures the sum of bases gained from hits in the game—singles count as one, doubles as two, triples as three, and home runs as four—aggregated for the market's defined participants (check the platform for whether this is combined team total or a team-specific total).

The 31 outcomes provide a set of discrete possible totals (or ranges) the market uses to capture different total-base scenarios; review the outcome labels on KALSHI to see whether they are integer totals or binned ranges and how they map to actual on-field totals.

The market close is listed as TBD; in practice such markets usually close shortly before the scheduled first pitch or when lineups are locked—watch the KALSHI market page and announcements for the official close time.

Whether extra innings count depends on the market's settlement rules on KALSHI; many baseball markets include all official play through extra innings, but always confirm the event-specific rules on the platform before trading.

Key items are the confirmed starting pitchers and their handedness, the posted offensive lineups (look for late scratches or power hitters missing), weather/wind updates at the ballpark, any announced bullpen usage patterns, and injury reports—each can materially shift expected total bases.
