Mariners vs Nationals Prediction

The Nationals haven’t scored more than three runs in each of their last four games, and now they’re throwing out Williams, who has allowed 25 hits and 16 earned runs in his last 19.1 innings. Williams is allowing a .305 batting average on the season, and he’s giving up a 6.29 ERA and .333 allowed batting average in 24.1 road innings. Kirby was rocked in his season opener, but he’s pitched just 3.2 innings this season. The jury is still out on Kirby. The Nationals are a tough sell in this spot. I’ll side with the Mariners and the RL for max betting value.
