No one was happier to watch Friday’s Game 5 of the ALDS than the Toronto Blue Jays.
The Seattle Mariners and Detroit Tigers were forced to expend every ounce of energy and just about every arm on their pitching staffs to survive a historically long, series-deciding contest that didn’t wrap up until after 1 a.m. on the East Coast.
Back on the West Coast, it was pandemonium. T-Mobile Park erupted when Jorge Polanco laced a walk-off single to right field, sending the Mariners to the ALCS for the first time since 2001 and handing the Tigers an absolutely crushing, season-ending defeat.
Here’s a look at where Friday’s marathon Game 5 ranks among the longest winner-take-all postseason games and more.

The Braves and Astros became the first teams to play 18 innings in a playoff game during Game 4 of the 2005 NLDS. They were later joined by the Giants vs. Nationals in the 2014 NLDS, the Red Sox vs. Dodgers in the 2018 World Series, and the Mariners vs. Astros in the 2022 ALDS.
Exhaustion didn’t seem to hold them back. The 2005 Astros, 2014 Giants, and 2022 Astros all went on to reach the World Series, while the Red Sox and Dodgers were already competing there.
Longest games in baseball history
Tigers vs. Mariners still had a long way to go to touch the longest games in MLB history, a list led by a 26-inning, 1-1 tie between the Brooklyn Robins:
| Teams | Date | Innings | Game Length | Result |
| Robins vs. Braves | May 1, 1920 | 26 | 3 hours, 50 minutes | Tied 1-1 |
| Cardinals vs. Mets | Sept. 11, 1974 | 25 | 7 hours, 4 minutes | Cardinals win 4-3 |
| Brewers vs. White Sox | May 8, 1984 | 25 | 8 hours, 6 minutes | White Sox win 7-6 |
| Athletics vs. Americans | Sept. 1, 1906 | 24 | 4 hours, 40 minutes | Athletics win 4-1 |
| Tigers vs. Athletics | July 21, 1945 | 24 | 4 hours, 48 minutes | Tied 1-1 |
| Mets vs. Astros | April 15, 1968 | 24 | 6 hours, 6 minutes | Astros win 1-0 |
If another game is going to join this list, it's almost certainly going to have to come in the postseason due to extra inning rules that put an automatic runner on second base during the regular season. Few games last beyond 12 innings under the current format, but the "ghost runner" is eliminated during the postseason.
