What Is The Seattle Mariners vs Toronto Blue Jays Timeline?
The seattle mariners vs toronto blue jays timeline stretches back nearly five decades. Both teams joined Major League Baseball as expansion clubs in the same season, and they have crossed paths in the American League ever since.
For most of their shared history, these two teams were simply divisional strangers who met a handful of times each year. That changed in 2022, when the postseason turned them into true rivals. Then in 2025, they clashed again on the biggest stage of all, the American League Championship Series.
Here is a quick snapshot of the journey:
- Late 1970s: Both franchises begin play as new American League teams and start facing each other in the regular season.
- 1990s: Toronto builds a powerhouse that wins back to back World Series titles, while Seattle grows into a competitive West Coast club.
- 2001: The Mariners tie the MLB record for wins in a season, adding fuel to their AL identity.
- 2022: Seattle ends a twenty one year playoff drought and sweeps Toronto in the AL Wild Card round.
- 2025: The Blue Jays and Mariners meet again, this time in a seven game American League Championship Series for a trip to the World Series.
When Did The Mariners First Play The Blue Jays?
The Mariners and Blue Jays first met during the 1977 season. Both franchises entered the American League as expansion teams that year, so their history together is almost as old as each club itself. Early meetings were simple regular season games with little national attention, since neither team was competing for championships yet.
It took decades before this matchup grew into something fans circled on their calendars. The seattle mariners vs toronto blue jays timeline stayed fairly quiet through the 1980s and 1990s, aside from Toronto building one of the great teams of that era.
What Is The All Time Head To Head Record Between The Mariners And Blue Jays?
As of the most recent completed season, the Blue Jays hold the edge in the all time series. Toronto has won roughly 228 regular season games against Seattle, while the Mariners have won around 209. Once you add playoff games into the mix, the Blue Jays lead the overall series record, sitting a bit above the Mariners.
That gap looks bigger on paper than it feels on the field. Many of those extra Toronto wins came from seasons decades ago. In more recent years, these two teams have played each other tightly, often trading series wins and close finishes.
Here is a simple breakdown:
- Regular season only: Blue Jays lead by roughly 19 games.
- Including playoffs: Blue Jays still hold a slight overall edge.
- Postseason series: Tied at one series win apiece.
Have The Mariners And Blue Jays Met In The MLB Playoffs?
Yes, and this is the part of the seattle mariners vs toronto blue jays timeline that fans talk about most. The two teams have met in October twice.
The first playoff meeting came in the 2022 AL Wild Card Series. Seattle swept Toronto in two games to win the best of three series and advance to the ALDS. It was Seattle’s first postseason appearance in twenty one years.
The second meeting arrived in 2025, and it was even bigger. The Mariners and Blue Jays battled through a full seven game American League Championship Series with a World Series trip on the line. Toronto won Game 7 to punch its ticket to the Fall Classic against the Los Angeles Dodgers.
So right now, the postseason series record between these two clubs sits at one win each, making this one of the more evenly matched rivalries in the American League.
