  • Did Not Play (DNP): If a player is not in the starting lineup, any entries involving that player will be marked as DNP, even if they later appear in the game (e.g., as a pinch hitter or reliever).

  • Player Entry Is Action If:

    • Batters: Must be in the starting lineup and record at least one official at-bat (intentional walks do not count).

    • Pitchers: Must be in the starting lineup and complete at least one full inning pitched.

  • Extra Innings: All stats earned in extra innings count toward the final result.


MLB Game Status Rules

  • Canceled / Postponed / Not Started: If the game is canceled, postponed, or never begins, all related props are voided and marked as DNP.

  • Shortened Games: If a game is shortened but deemed official by MLB (e.g., due to weather after 5 innings), stats count, and all props will be scored normally.

    • In a shortened game, our player props are based on the "already determined" rule. If the prop has already been decided (e.g., a player hits a home run before the game is called), the pick stands. If not, or if the outcome could still change, the pick is voided.

  • Suspended Games: If a game is suspended, it will remain open until officially resumed and completed. Final stats from the completed game will apply to entries.

Pitcher Prop Rules

Each pitcher's prop is graded based on individual performance during their outing, using official MLB statistics.

General Rule for Action:

  • The pitcher must start the game and throw at least one pitch.

  • Once a pitch is thrown, all prop categories are action, even if the pitcher is removed early (due to injury, pitch count, or coach decision).

  • If the pitcher does not start the game, the prop will be voided and marked DNP (Did Not Play).

Pitcher Prop Categories:

  • Strikeouts (K):
    Total strikeouts recorded by the starting pitcher.
    Action if the pitcher starts and throws at least one pitch.

  • Hits Allowed:
    Total hits surrendered by the starting pitcher.
    Action if the pitcher starts and throws at least one pitch.

  • Earned Runs (ER):
    Total earned runs given up by the starting pitcher.
    Action if the pitcher starts and throws at least one pitch.

  • Walks Allowed (BB):
    Total number of walks issued by the starting pitcher.
    Action if the pitcher starts and throws at least one pitch.

  • Outs Recorded:
    The total number of outs the starting pitcher records during their appearance. (e.g., 5.2 innings = 17 outs)
    Action if the pitcher starts and throws at least one pitch.

Note: All props are based solely on the pitcher’s performance during their outing. Stats recorded after they leave the game are not counted.
