Origins of the Seattle Mariners and Houston Astros
To understand the Seattle Mariners vs Houston Astros timeline, it is important to first look at the history of both franchises.
The Seattle Mariners were established in 1977 and became the first MLB franchise located in the Pacific Northwest. Over the years, the team gained popularity through iconic players such as Ken Griffey Jr. and Ichiro Suzuki, who helped define the Mariners’ identity as an exciting offensive team.

Although both teams existed in MLB for decades, their rivalry truly intensified when Houston moved to the American League.
