Half a Century of M's Baseball: Which Historic Mariners Season Deserves the Crown?

The Seattle Mariners are turning 50 this season, and that means it's time to settle a debate that has been heating up in Seattle sports bars for decades: what's actually the best season in franchise history? Here's the thing, though. The Mariners have had way more forgettable years than memorable ones. But when those great seasons happened, they mattered. Some of them still echo through Pacific Northwest sports lore, and a couple even carved themselves into baseball history itself. This list is going to get people fired up, and that's exactly how it should be.

The Honorable Mentions That Almost Made It

Before we get to the real rankings, let's give some love to the seasons that just missed the cut. Back in 1977, nine years after the Pilots skipped town for Milwaukee, the Kingdome was packed for Diego Seguí's first pitch and the "maiden voyage" of the Mariners was officially underway. In 1997, the M's won their second division title in three years with an absolutely stacked roster. Ken Griffey Jr. was the AL MVP with 56 homers and 147 RBIs. Randy Johnson went 20-4 and finished second in Cy Young voting. And yet Baltimore swept them out of the ALDS in four games. That might have been the most talented Mariners team in history at that point, but October had other plans. Then there's 2000, when the M's were in transition without Griffey and heading toward losing Alex Rodriguez. Even without their big names, they still won 91 games, beat the White Sox in the ALDS, and pushed the eventual champion Yankees to six games in the ALCS.

The Top Five That Define an Era

At number 5 sits 1991, the first winning season in franchise history. The M's went 83-79 after 15 seasons of heartbreak. Ken Griffey Jr. hit .327 with 100 RBIs. Edgar Martínez showed he was going to be a hitting machine. Jay Buhner became the full-time right fielder. Randy Johnson struck out 228 batters and truly became the ace. This season laid the groundwork for everything that came next.

Number 4 has to be 2022, when Cal Raleigh ended the 21-year playoff drought with a walk-off against the A's on September 30th. That swing clinched a playoff berth and meant Seattle finally wasn't a playoff desert anymore. Julio Rodríguez won Rookie of the Year. Logan Gilbert and George Kirby established themselves in the rotation. Luis Castillo arrived as the ace. The wild part? The M's were 10 games under .500 in mid-June. They pulled off a 14-game winning streak that changed everything.

At number 3 sits 2001, the year the Mariners tied the major league record for wins with Ichiro's arrival launching what everyone called Ichi-mania, even though playoff shortcomings kept it from being number one.

What's coming in season 50? If expectations pan out, this list could get rewritten fast.
