Important Note About Projections and Odds
Sportsbook props and Underdog projections are not interchangeable. A sportsbook may offer an over/under with odds attached, while Underdog generally asks users to select whether a player will finish higher or lower than a posted projection. Lines can also differ across operators and change as lineups, weather, and pitching plans are confirmed.
Before submitting an entry:
- Confirm that the player is active and expected to start.
- Check the projection shown inside Underdog rather than relying on a third-party number.
- Review weather and lineup updates.
- Understand how ties, postponed games, shortened appearances, and late scratches are graded.
- Read the rules for the specific game format available in your jurisdiction.
