Prediction: Washington Nationals VS Arizona Diamondbacks 2025-05-30

The Washington Nationals are looking to keep their momentum going after a thrilling 9-3 win over the Seattle Mariners, where Josh Bell hit a three-run homer in the 10th inning and rookie Daylen Lile got his first MLB RBI. Now, they're heading to Chase Field to face the Arizona Diamondbacks, who have a 52.8% win rate when favored.

The Diamondbacks will start Merrill Kelly (5-2, 3.52 ERA, 8.2 K/9), while the Nationals will counter with Jake Irvin (4-1, 3.42 ERA, 2.47 K/BB). The Diamondbacks' Corbin Carroll leads the team with 16 home runs, while the Nationals' James Wood has 15 home runs and a .287 batting average.

The odds are in favor of the Diamondbacks, with a moneyline price of 1.44 (FanDuel) and a spread of -1.5 (1.95, BetOnline.ag). However, the Nationals have won 50% of their games as underdogs this season.

My best bet for this game is the Nationals +1.5 (1.89, DraftKings). The Nationals have shown they can compete with anyone, and their recent win over the Mariners proves they have the firepower to take down a tough opponent. With Irvin on the mound, they have a good chance to keep the game close, and the +1.5 spread gives them a bit of cushion.

As for the total, I'm leaning towards the Under 9.0 (1.98, BetMGM). Both Kelly and Irvin have been solid on the mound, and the Diamondbacks' bullpen has been decent. The Nationals' offense has been streaky, but they might struggle to score against Kelly.

So, there you have it - Nationals +1.5 and Under 9.0. Let's see if the Nationals can keep their momentum going and take down the Diamondbacks!
