The Washington Nationals have outscored the Arizona Diamondbacks 20-2 [1] across two wins as they enter the series finale on Sunday.

This dominant performance marks a significant momentum shift for Washington during the MLB Sunday Leadoff series. The Nationals are currently playing what has been described as explosive baseball while visiting Phoenix.

The streak began on Friday, June 5, 2026, when the Nationals secured a 14-1 [2] victory in the series opener. That game set the tone for the weekend, leaving the Diamondbacks struggling to contain the Washington offense at Chase Field [5].

The two teams meet again this Sunday, June 7, 2026 [3], for the final game of the set. The matchup serves as a critical opportunity for Arizona to recover from the early deficit and prevent a series sweep on their home turf.

Fans can watch the series finale via the Peacock streaming platform [4]. The game remains a focal point of the MLB Sunday Leadoff schedule, highlighting the contrast in offensive production between the two clubs over the last few days.

Washington's ability to maintain this scoring pace will be the primary storyline as the game begins. The team has leveraged a high-powered attack to stifle Arizona's pitching and defense throughout the stay in Phoenix.
