I know the Nationals are the better team at bat, but the pitching matchup lies with Seattle who will be starting Luis Castillo who has a 4-2 home record (0 road wins) Nationals will have Trevor Williams on the mound and he's not the most trusted pitcher to be putting money on. The safest play is the Under 8 runs, with the Mariners at home and their ability to slow down the bats of Washington, and with the poor batting of the Mariners let's take the Under.

Official Play: Under 8 Runs
