Royals vs Red Sox: How to Make DFS Picks at Underdog

The Royals vs Red Sox DFS contests at Underdog require you to build a squad containing between two and eight players from the two teams. Each player will have a protected stat attached to them (for example, total strikeouts or total hits), and your task is to predict whether their actual stat line will be higher or lower than their projection.

In Standard Underdog DFS contests, you need to get all of your predictions correct to win a prize, but if you opt for a Flex contest, you can still receive a small payout, even if one or two of your predictions are incorrect.
