How to Make Your Red Sox vs Yankees DFS Picks at Underdog

Using your Underdog $50 bonus on the Red Sox vs Yankees clash requires you to pick a squad of between two and eight players. Each player will have an in-game stat attached to them (for example, total hits or strikeouts). Your task is to predict whether each player’s actual statistical output will be higher or lower than the projected amount.

If you enter a standard Underdog DFS contest, you need to get all of your Higher/Lower predictions correct to win a prize. However, if you decide to enter a Flex DFS contest, you will receive a smaller payout, even if one of your picks is incorrect.
