The holiday weekend will end with multiple great MLB games on Sunday. These are some of the matchups and prices for contracts:
- Astros (38%) vs. Dodgers (64%)
- Cardinals (36%) vs. Cubs (66%)
- Rangers (46%) vs. Padres (56%)
- Giants (49%) vs. Athletics (53%)
This means you can buy a single contract for the Padres at 56 cents. If they end up winning, this contract will result in a $1 payout. But you will also have the chance to sell your contracts during the action.
Let’s say the Padres jump out to an early lead. You can try to sell your contracts to secure winnings, and the end outcome wouldn’t matter.
