Franchise knowledge
Seattle Mariners
Seattle American League West
The Seattle Mariners are baseball’s unfinished Northwest epic — born in 1977 to replace the short-lived Pilots, housed first under the Kingdome’s roof, and still the only active major-league franchise never to reach the World Series. Superstars, a saved city in 1995, and a 116-win season that still didn’t end in a pennant define the club’s distinctive ache.
From Ken Griffey Jr.’s reverse-cap swing to Edgar Martínez’s Double, from Ichiro’s 242 hits to Félix Hernández’s King Félix years to Julio Rodríguez and Cal Raleigh’s modern surge, Mariners baseball has produced greatness without the final banner. T-Mobile Park waits for the October round every other franchise has seen.

Seattle Mariners
Origins
Major-league baseball returned to Seattle in 1977 after the Pilots lasted a single 1969 season and fled to Milwaukee. The expansion Mariners played in the Kingdome — a concrete cavern of multi-purpose baseball where early years were mostly losing, though Gaylord Perry won a 1978 Cy Young and flashes of pitching talent kept hope alive under the roof. The founding story lives in the Team Origin quiz.
The franchise’s identity coalesced in the 1990s. Ken Griffey Jr.’s swing and smile made Seattle a national club; Randy Johnson’s overpowering left arm owned the Kingdome; Edgar Martínez turned designated-hitter artistry into a Hall of Fame case; Jay Buhner supplied the power and the mullet. Lou Piniella managed a club that finally mattered. Dig into that era with the Ken Griffey Jr. quiz and the Edgar Martínez quiz.
In 1995, down 2–1 to the Yankees in the ALDS, Seattle won Game 5 on Martínez’s double — “The Double” — and saved baseball in the city as a new-ballpark campaign took flight. That October is still the emotional origin of modern Mariners fandom. Relive it in the 1995 Mariners quiz.
Seattle Mariners
History
Safeco Field — now T-Mobile Park — opened in 1999 with a retractable roof suited to Puget Sound weather. The late-1990s clubs kept contending: the 1997 Mariners and the 2000 club reached October without breaking through. Then came the near-miss that still defines the franchise.
The 2001 Mariners won 116 games, tying the 1906 Cubs for the American League’s modern high — Ichiro Suzuki’s 242 hits, a relentless lineup, a deep staff — and still lost the ALCS to the Yankees. They have never reached the World Series. Ichiro’s 2001 MVP and Rookie of the Year, his hitting style imported from Japan, and later his 3,000th hit expanded the sport’s global footprint. Relive the peak in the 2001 Mariners quiz and the Ichiro quiz.
After a long stretch of losing in the 2010s, Seattle rebuilt around Félix Hernández’s King Félix peak, then Julio Rodríguez, a new wave of pitching, and a 2022 return to the postseason — the club’s first playoff series win since 2001. Covered in the 2022 Mariners quiz.
Scott Servais’s 2023 club won 88, finished third, and missed October by two games behind Houston — Julio’s 32 homers, Castillo’s 14 wins. The 2024 team won 85 under Servais (later Dan Wilson), finished second, and still missed the dance; Cal Raleigh led with 34 homers, George Kirby with 14 wins. Wilson’s 2025 Mariners won 90, took the West, beat Detroit in the ALDS, and lost a seven-game ALCS to Toronto — Raleigh’s MLB-leading 60 homers the loudest chapter yet in a franchise still chasing a pennant.
Seattle Mariners

Seattle Mariners
Oddities
Mariners lore is a dome, a double, a 116-win heartbreak, and a pennant that still hasn’t arrived.
- Pilots’ ghost: Seattle lost the Pilots after one season in 1969. The Mariners arrived in 1977 as the city’s second chance. See the Team Origin quiz.
- The Kingdome: Multi-purpose concrete, loud when full, empty when not — home until Safeco opened in 1999. Griffey’s catches off the wall still live in highlight reels.
- The Double: Edgar Martínez’s ALDS Game 5 line drive scored Griffey from first and saved baseball in Seattle. The 1995 Mariners quiz and the Edgar Martínez quiz share that moment.
- 116 and out: The 2001 club tied the modern AL win record and never reached the World Series. Ichiro’s 242 hits still stand; the ALCS loss to New York still hurts. Covered in the 2001 Mariners quiz.
- Only franchise without a pennant: Every other active club has at least one World Series appearance. Seattle’s unfinished business is the brand.
- Junior’s swing: Griffey’s uppercut and backward cap made the Mariners a national product in the 1990s. The Ken Griffey Jr. quiz is the roll call.
- Ichiro from Japan: MVP and Rookie of the Year in the same season, a hitting style that changed scouting, and later 3,000 hits. See the Ichiro quiz.
- Raleigh’s 60: Cal Raleigh led MLB with 60 homers in 2025 — a catcher-slugger peak in a West-title season that still ended in the ALCS. Test it in the 2025 Mariners quiz.
- Two games short: The 2023 club finished two behind Houston and missed October entirely — proof that 88 wins don’t always buy a ticket. See the 2023 Mariners quiz.
The roster of memory
Notable Players
Legends, franchise faces, and the names every Seattle Mariners fan should know.
Ken Griffey Jr.
The Kid
Hall of Fame center fielder whose swing, smile, and backward cap made Seattle a national club in the 1990s. Griffey’s Kingdome catches and 1995 October are still the franchise’s most replayed images. He returned late in his career to finish where it started. Dig deeper in the Ken Griffey Jr. quiz.
Edgar Martínez
The Double
Hall of Fame designated hitter whose line-drive artistry and 1995 ALDS Game 5 double saved baseball in Seattle. Martínez made the DH a craft, not a compromise — and gave the franchise its most important single swing. See the Edgar Martínez quiz.
Ichiro Suzuki
2001 MVP & Rookie of the Year
Hall of Famer who arrived from Japan and immediately won MVP and Rookie of the Year — 242 hits in 2001, a 116-win supporting cast, and a hitting style that changed how the sport scouted. Ichiro’s Seattle years are the modern franchise’s global face. Relive them in the Ichiro quiz.
Félix Hernández
King Félix
Ace of the 2010s — Cy Young seasons, a perfect game, and a generation of T-Mobile nights built around his changeup. Félix carried losing clubs and briefly contended ones with equal theater. His peak is the bridge between Ichiro’s era and the Julio rebuild.
Julio Rodríguez
J-Rod
Center fielder whose Rookie of the Year debut and power-speed game announced Seattle’s modern contention window. Julio led the club in homers in 2023 and remains the face of the post-2022 clubs. Covered across the 2022, 2023, and 2025 Mariners quizzes.
Jay Buhner
Bone
Power-hitting right fielder whose mullet and home runs completed the Griffey–Edgar core of the 1990s. Buhner’s Kingdome thunder and 1995 October are still Seattle folklore. Covered with that club in the 1995 Mariners quiz.
Cal Raleigh
Big Dumper
Switch-hitting catcher whose power peak — 34 homers in 2024, an MLB-leading 60 in 2025 — made him the cleanup threat of the Dan Wilson clubs. Raleigh’s 2025 West title and ALCS run are covered in the 2024 and 2025 Mariners quizzes.
Alex Rodriguez
Young shortstop phenom
Shortstop whose Seattle years — batting titles, MVP-caliber seasons, and the 1995–2000 contention window — made him the third star beside Griffey and Edgar before free agency took him to Texas. His Mariners chapter sits inside the 1995, 1997, and 2000 Mariners quizzes.
