The Red Sox vs Astros matchup has become one of the most compelling modern rivalries in Major League Baseball, defined not by decades of traditional animosity but by a series of high-stakes, dramatic playoff confrontations. This rivalry, born in the crucible of postseason baseball, has captivated fans with its unpredictable nature, memorable moments, and a constant ebb and flow of power. 

From the Astros’ ascent to perennial contenders to the Red Sox’s resilient attempts to reclaim their spot atop the American League, the clashes between these two clubs have consistently delivered must-watch baseball. 

The Genesis of a Rivalry: A Postseason Power Struggle

The animosity between the Red Sox and Astros didn’t originate from a shared divisional history or a century of competing for the same fans. Instead, it was forged in the heat of three significant American League Championship Series (ALCS) matchups over a short, intense period. 

Before 2017, the two teams rarely faced off, with the Astros having spent most of their history in the National League. The rivalry truly began when the Astros moved to the American League in 2013, setting the stage for future playoff showdowns.

A Timeline of Postseason Battles

2017 ALCS: The first major postseason clash came in 2017. The Astros, a young and hungry team, defeated the Red Sox in four games to advance to their first World Series as an American League club. This series, which the Astros won 4-1, was a coming-out party for a roster filled with stars like Jose Altuve and Carlos Correa. 

While the Red Sox were a strong team, they were simply outmatched by a superior Astros squad that would go on to win the World Series. This series set the tone, with the Astros establishing themselves as the new powerhouse.

2018 ALCS: The very next year, the tables turned. The Red Sox, fresh off a franchise-record 108 regular-season wins, sought revenge. Led by Mookie Betts and J.D. Martinez, the Red Sox dominated the Astros, winning the series 4-1. 

This victory was particularly sweet for Boston fans, as it was a decisive win against the team that had ended their season the year before. The Red Sox would go on to win the World Series, cementing their place as one of the greatest teams in franchise history.

2021 ALCS: The most recent and arguably most contentious playoff series took place in 2021. After the Red Sox won a thrilling Wild Card game and upset the Tampa Bay Rays in the Division Series, they faced the Astros again in the ALCS. The Red Sox took a 2-1 series lead, and with a chance to take a commanding 3-1 lead at home, everything seemed to be going their way. 

However, the Astros mounted an epic comeback, winning three straight games to close out the series, including a crucial Game 4 where they scored seven runs in the ninth inning. This series showcased the resilience of the Astros and the fragility of a Red Sox team that ultimately ran out of gas.

These playoff meetings have created a deep-seated rivalry rooted in mutual respect, but also a fierce desire to win. For fans, these games are not just about a single win or loss; they are about continuing a narrative of triumph and heartbreak that has been built over nearly a decade.

The Modern-Day Matchup: A Look at the 2025 Season

As of the 2025 season, the Red Sox vs Astros dynamic has evolved once again. Both teams have seen significant roster changes, with key players leaving and new stars emerging. The rivalry is now less about the star players of the past (like Mookie Betts or Carlos Correa) and more about new faces and team-wide trends.

Boston Red Sox: A Rebuilt Roster and Renewed Hope

The Boston Red Sox entered the 2025 season with a mix of veteran talent and promising young prospects. After a period of rebuilding, the Red Sox are looking to return to their winning ways.

Key Players and Trends (2025):
