Washington Nationals vs Diamondbacks Timeline

While they have never developed the intensity of a divisional rivalry, their meetings have consistently featured postseason contenders, future Hall of Famers, and some unforgettable games.

From Arizona’s rapid rise to a World Series title in 2001 to Washington’s championship run in 2019, both franchises have experienced dramatic highs. Every meeting has added another chapter to a head-to-head history that continues to evolve.

1998: The First Meetings

The rivalry began during the Diamondbacks’ inaugural MLB season. Arizona Diamondbacks, one of baseball’s newest franchises, faced the Montreal Expos for the first time as both clubs started building their identities in the National League. Although neither franchise had much shared history, the early meetings established a competitive series that would continue after the Expos relocated to Washington.

2001: Arizona Reaches the Top

Only four seasons after entering the league, the Diamondbacks won the World Series behind Randy Johnson and Curt Schilling. While this achievement was not directly tied to the Nationals, it marked the beginning of Arizona becoming one of the National League’s most respected organizations whenever the teams met.

2005: The Nationals Era Begins

The Montreal Expos officially became the Washington Nationals in 2005, giving the rivalry a fresh identity. From that point forward, every matchup became part of the Nationals’ history rather than the Expos’, introducing a new era for both franchises.

2012–2019: Washington’s Championship Window

Washington emerged as one of baseball’s strongest teams during the 2010s. Led by stars including Bryce Harper, Max Scherzer, Anthony Rendon, Stephen Strasburg, and Juan Soto, the Nationals became regular postseason contenders.

Their historic 2019 World Series championship represented the peak of the franchise and added another layer of prestige whenever they faced Arizona.

2024: Arizona’s Offensive Explosion

One of the most memorable games in the rivalry came on July 30, 2024, when the Diamondbacks defeated Washington 17-0. The lopsided victory showcased Arizona’s explosive offense and became one of the largest winning margins in the history of the matchup.

2025: The Series Tightens
