Houston Astros
Houston American League West
The Houston Astros are baseball’s space-age original — born as the Colt .45s, housed in the Eighth Wonder of the World, and rebuilt into a 21st-century October machine. Two World Series titles, a league switch, and a scandal that still follows the 2017 club give Houston one of the sport’s most eventful modern histories.
From mosquito-haunted Colt Stadium to the Astrodome to Minute Maid Park, from the Killer B’s near-misses to José Altuve’s October, Astros baseball has been about reinvention: expansion curiosity, a pioneering dome, and a dynasty that won big, was punished in the court of public opinion, and kept winning anyway.

Apr 10, 1962

Apr 12, 1965

Sep 25, 1986

Houston Astros
Origins
The franchise began in 1962 as the Houston Colt .45s, a National League expansion team that played in a mosquito-haunted outdoor park while a dome rose downtown. On April 12, 1965, the club moved into the Astrodome — the so-called Eighth Wonder of the World, the first large indoor stadium in the majors — and renamed itself the Astros to match the space-age venue. Indoor baseball, an exploding scoreboard, and later the rainbow uniforms made Houston look like the future even when the standings did not.
Early decades mixed novelty with gradual competence. Jimmy Wynn, César Cedeño, and José Cruz built a regional following. Nolan Ryan’s Houston years — strikeouts, no-hitters, and a Texas legend in orange — proved the dome could house an ace. The Nolan Ryan quiz covers that chapter; the founding story lives in the Team Origin quiz.
The 1980 and 1986 clubs established Houston as a legitimate October threat. Mike Scott’s 1986 Cy Young and a no-hitter that clinched the West set up a heartbreaking NLCS loss to the Mets — Game 6 extras that still sting along the Gulf. From Colt Stadium to the Dome, the origin story is expansion baseball inventing a look, then waiting for the wins to catch up.

History
The 1990s and 2000s belonged to the Killer B’s. Jeff Bagwell, Craig Biggio, and Lance Berkman produced a string of division titles and the 2005 National League pennant — the franchise’s first — before a World Series sweep by the White Sox. Bagwell’s 1994 MVP, Biggio’s 3,000 hits, and Minute Maid Park (opened in 2000 as Enron Field) made Houston a National League fixture. Dig into that era with the Jeff Bagwell quiz, the Craig Biggio quiz, and the Killer B’s quiz.
A brutal rebuild and a 2013 move to the American League West reset the franchise. Under Jeff Luhnow the Astros drafted and developed a new core: José Altuve, George Springer, Carlos Correa, Alex Bregman, Dallas Keuchel. The 2017 club beat the Dodgers in seven for the first World Series title — a championship later shadowed by a sign-stealing scandal, suspensions, lost draft picks, and a lasting stain on that October’s public reputation. The 2017 Astros quiz and the José Altuve quiz sit at the center of that argument.
On the field, Houston did not fade. The Astros returned to the World Series in 2019 and 2021, then won again in 2022 over Philadelphia under Dusty Baker — framed as organizational resilience as much as roster talent. Justin Verlander’s late-career Cy Youngs and a homegrown infield kept Minute Maid an October address. Relive the second ring in the 2022 Astros quiz.
Baker’s 2023 club won 90, took the West, beat Minnesota in the ALDS, and lost a seven-game ALCS to Texas. Joe Espada’s 2024 team won 88 and another West title, then was swept by Detroit in the wild-card round. The 2025 Astros won 87, finished second, and missed October — Framber Valdez and Hunter Brown still the rotation’s spine, a dynasty catching its breath.

Houston Astros
Oddities
Astros lore is indoor baseball, rainbow polyester, and an October machine that the rest of the sport still argues about.
- Colt .45s: The expansion nickname lasted three seasons — mosquitos, outdoor heat, and a gun-themed brand before the dome took over. See the Team Origin quiz.
- Eighth Wonder: The Astrodome was the first large indoor big-league park. When grass died under the roof, Houston invented Astroturf and changed how baseball looked for a generation.
- Rainbow uniforms: The 1970s–80s tequila-sunrise unis remain the loudest clothes in franchise history — and a merch revival decades later.
- Scott’s clincher: Mike Scott no-hit San Francisco on September 25, 1986, to clinch the West — then the Mets ended the dream in an NLCS still replayed in Houston.
- Killer B’s: Bagwell, Biggio, and Berkman made the 1990s–2000s a batting-order brand. The Killer B’s quiz is the roll call.
- League switch: Houston jumped from the NL to the AL West in 2013 — one of the rare modern franchise realignments — and immediately started building an AL dynasty.
- The scandal: The 2017 sign-stealing operation brought suspensions, vacated draft picks, and a title that many fans refuse to put in the same sentence as 2022. Covered, as baseball, in the 2017 Astros quiz.
- Baker after the fire: Dusty Baker’s 2022 championship, inherited in the scandal’s aftermath, became the organization’s argument that the roster could win in the open.
- Tigers in two: The 2024 West champions were swept in the wild-card round by Detroit — a reminder that October does not care about the regular-season banner. See the 2024 Astros quiz.
The roster of memory
Notable Players
Legends, franchise faces, and the names every Houston Astros fan should know.
Jeff Bagwell
1994 NL MVP
Hall of Fame first baseman whose 1994 MVP season and Killer B’s peak defined Houston’s first sustained contention window. Bagwell’s wide stance and production made the Astrodome and Minute Maid feel like a hitter’s office. Dig deeper in the Jeff Bagwell quiz.
Craig Biggio
3,000 hits
Hall of Famer who caught, played second, and moved to the outfield — a 3,000-hit lifer who never wore another big-league uniform. Biggio’s dirt-stained helmet is still the image of the Killer B’s years. See the Craig Biggio quiz.
Nolan Ryan
Texas legend
Hall of Fame flamethrower whose Houston chapter included no-hitters, strikeout milestones, and the proof that the Dome could house an ace. Ryan’s Astros years sit between California and Arlington — and still belong to orange. Relive them in the Nolan Ryan quiz.
Lance Berkman
Big Puma
Switch-hitting slugger who completed the Killer B’s and carried Houston to the 2005 pennant. Berkman’s bat made the early Minute Maid years an offensive show. Covered with his teammates in the Killer B’s quiz.
José Altuve
2017 AL MVP
Undersized second baseman who became the face of the modern dynasty — batting titles, a 2017 MVP, and two World Series rings. Altuve’s October is Houston’s October. Dig into it in the José Altuve quiz.
Justin Verlander
Late-career Cy Youngs
Acquired mid-2017, Verlander immediately helped deliver a title and then piled up Cy Young-caliber seasons in orange. His Houston peak is the pitching half of the dynasty’s first two World Series trips.
Alex Bregman
October fixture
Third baseman whose bat and infield presence anchored the 2017 and 2022 champions. Bregman’s Houston chapter closed after 2024 — but the October ledger stays. See the 2022 Astros quiz.
Yordan Alvarez
Middle-of-the-order thunder
Left-handed slugger whose 2019 Rookie of the Year debut and later 30-homer seasons made him the cleanup threat of the post-scandal clubs. Alvarez led Houston in homers in 2023 and 2024 — covered in the 2023 and 2024 Astros quizzes.
