Red Sox vs Dodgers: How To Make Your DFS Picks at Underdog

To enter a Red Sox vs Dodgers DFS contest at Underdog, you need to create a team containing between two and eight Red Sox or Dodgers players. Each player will have a projected statistic attached to them, and your task is to predict whether each player’s actual in-game stat will be more or less than that projection.

If you take part in a Standard Underdog DFS contest, you need to get all of your predictions correct to win a prize, but if you elect to enter a Flex contest, you can still pick up a prize even if a couple of your picks are incorrect.
