Mariners vs Nationals Prediction

The Nationals are 7-3 in their last 10 meetings against the Mariners and are 4-2 in their last 6 meetings in Washington.

In this Mariners vs Nationals Prediction, the Mariners are coming as -150 road favorites. I like the Mariners in a bounce-back spot today with Hancock on the mound, who has not given up more than two runs in seven of his last eight starts and has a sub-1.00 WHIP. On the flip side, Mikolas sits on a terrible 7.94 home ERA and the Mariners have the 6^th-best bullpen in baseball. Take the Mariners in this one.
