Team Breakdown:

Arizona Diamondbacks:

The Arizona Diamondbacks come into this game with a 36-38 record, including a 17-20 mark on the road. They have shown some inconsistency this season, which has them positioned in the middle of the National League West standings.


Ryne Nelson will start for the Diamondbacks. He has a 4-5 record with a 5.49 ERA and a 1.64 WHIP over 57.1 innings. Nelson has struggled with control and has been prone to giving up runs, which could be a significant factor in this game.


The Diamondbacks' offense is led by Christian Walker, who has 16 home runs and 49 RBIs. Ketel Marte also contributes significantly with a .282 batting average. However, their overall team average of .254 indicates some room for improvement.

Key Players:

  • Home Runs: Christian Walker (16 HR)
  • Batting Average: Ketel Marte (.282 AVG)
  • Runs Batted In: Christian Walker (49 RBI)

The Diamondbacks are dealing with several injuries, including Zac Gallen, Blake Walston, Miguel Castro, Alek Thomas, and Jose Castillo, which could affect their overall performance.


Washington Nationals:

The Washington Nationals hold a 36-37 record and are 17-18 at home. They are in a competitive position in the National League East standings, looking to gain ground with a win in this matchup.


MacKenzie Gore will take the mound for the Nationals. Gore has been solid this season with a 6-5 record, a 3.24 ERA, and a 1.32 WHIP over 75.0 innings. His ability to strike out batters (91 Ks) and limit home runs (6 HR) makes him a key asset for the Nationals.


The Nationals' offense features CJ Abrams, who has 11 home runs and a .261 batting average. Jesse Winker also provides a reliable presence at the plate with a .271 average and a .383 on-base percentage.

Key Players:

  • Home Runs: CJ Abrams (11 HR)
  • Batting Average: Jesse Winker (.271 AVG)
  • Runs Batted In: Joey Meneses (36 RBI)

Importantly, the Nationals are not dealing with any significant injuries, giving them a full roster to leverage in this game.

Game Odds:

Team Moneyline Total Run Line
ARI (36-38) +120 o8.5 (-130) +1.5 (-160)
WSH (36-37) -140 u8.5 (+110) -1.5 (+135)



The prediction for this game is that the Washington Nationals will win on the moneyline (ML). Here’s why:

MacKenzie Gore's strong pitching performance this season, combined with the Nationals' relatively healthier roster, gives them an edge over the Diamondbacks. Ryne Nelson's struggles on the mound for Arizona, particularly with his high ERA and WHIP, suggest that Washington's offense can take advantage. Furthermore, the Nationals' recent form, including their win in the previous game against Arizona, indicates they are in a better position to secure a victory.

Pick: Washington Nationals ML (-140)
