Washington has dropped two of its last three and just managed four runs combined in those losses. James Wood continues to provide the power with 13 home runs and 36 RBI, while CJ Abrams leads in batting at .294. The lineup has shown inconsistency, hitting .241 as a team with a .309 OBP and only 52 homers. Offensively, things have been hit or miss, but the team did recently take two games off Atlanta, which shows some upside when the bats click.

The Nationals are struggling on the mound, giving up a 5.07 team ERA and a 1.41 WHIP. Parker has been serviceable, but his 25 walks in 55.1 innings show control issues. The bullpen is in rough shape too, with five pitchers on the IL including Kyle Finnegan and Joan Adon. Opponents are batting .261 against Washington pitching, which is problematic heading into a matchup against a team with solid pop like Seattle.

Seattle returns home after a rough trip to Houston, where they dropped three of four. Still, the Mariners lead the AL West and have won three of the last six. Cal Raleigh leads with 17 home runs and 35 RBI, while J.P. Crawford has a team-best .379 OBP. The Mariners only hit .237 as a team, but make up for it with 70 homers and a better .325 OBP than Washington.

The Mariners have the clear edge on the mound, with a team ERA of 3.69 and opponents hitting just .255 against them. Evans has only allowed five homers over 27 innings and keeps his walks in check. Injuries to Bryce Miller and several bullpen arms could be a factor, but Seattle’s deep rotation and home-field advantage help soften that blow. The Mariners are 13-11 at T-Mobile Park and 13-7 in day games.

The Mariners have the better bullpen, a more consistent rotation, and more home run power than Washington. With Evans pitching better than Parker and Seattle's team ERA nearly 1.40 runs better, it's hard to side with a Nats squad that has been giving up runs and lacks pop. Final Score Prediction: Seattle Mariners win 5-3.
