HOUSTON -- It wasn’t until was inducted into the National Baseball Hall of Fame in 2015 that the Astros had their first player enshrined who had an Astros cap on his plaque. followed two years later and in 2025.

Biggio and Bagwell are undoubtedly the greatest two players who played the majority of their careers for the Astros. Biggio spent his entire 20-year career (1988-2007) in Houston, and Bagwell spent all 15 of his Major League seasons (1991-2005) with the Astros.

Several other players in the Hall of Fame have passed through Houston, including , , , and . There’s also a handful of players considered among the best in club history who aren’t in the Hall of Fame.

Here’s a list of the greatest retired Astros players not in the Hall of Fame:

1.
Key fact: His 52 bWAR is first among switch-hitters with fewer than 1,900 games played

Berkman, an outfielder turned first baseman, performed at a Hall of Fame caliber at his peak in the mid-2000s and played in 1,879 regular-season games in 15 seasons, amassing a .293 batting average, 422 doubles, 366 home runs, 1,234 RBIs and a .943 OPS that ranks 25th in Major League history. Still, he fell off the Hall of Fame ballot in 2019 after receiving only 1.2% the Baseball Writers’ Association of America vote in his first year.

In the decade from 2000-09, Berkman ranked in the top five in the National League in multiple categories, including second in RBIs (1,026); third in total bases (2,887), walks (968), doubles (357) and runs (959); fourth in homers (309) and on-base percentage (.413); and fifth in OPS (.972). He also was sixth in slugging (.559). In those 10 seasons, he posted an OPS higher than .900 nine times and higher than 1.000 three times.

2.
Key fact: Cedeno was the second player in Major League history to hit 20 homers and steal 50 bases in one season

Cedeno, signed by the Astros at age 16 out of the Dominican Republic, made his Major League debut at 19. He was compared to Willie Mays early in his career by manager Leo Durocher, but injuries took their toll. Still, Cedeno was an electrifying and dynamic center fielder for the Astros for a decade and is still considered perhaps one of the team’s top five offensive players in history.

With a rare combination of speed, power and defense, Cedeno was the second player in history (Lou Brock, 1967) to hit 20 homers and steal 50 bases in a season -- and he did it three years in a row (1972-74). The only Astros player to hit for the cycle twice, Cedeno won five consecutive NL Gold Gloves (1972-76) and appeared in four All-Star Games with the Astros.

In 12 years with Houston, Cedeno had a .289/.351/.454 slash line with 343 doubles, 55 triples, 163 homers, 778 RBIs and 487 stolen bases. He holds the club record for steals nearly 40 years after his final game with the Astros.

3.
Key fact: His 135 ERA+ was fifth highest in the Majors from 2001-10

Oswalt was the club’s ace in the early 2000s and didn’t take a back seat when Houston acquired Roger Clemens and Andy Pettitte before to the '04 season. Oswalt posted back-to-back 20-win seasons in '04 and '05 and helped the Astros go deep into the playoffs each time, including a clutch win in Game 6 of the '05 NL Championship Series in St. Louis to clinch Houston’s first pennant. (He was 4-0 with a 3.66 ERA in the postseason for Houston). Oswalt won 143 games in 10 seasons with the Astros, putting him one shy of Joe Niekro’s club record of 144.

A 23rd-round pick in the 1996 Draft, Oswalt was pitching at Class A Advanced Kissimmee in 2000 when he was called up to Double-A Round Rock to make a spot start.

“They called me up and said, ‘You’re going to pitch one game, and you’re going back to A ball,’” said Oswalt.

Instead, Oswalt struck out 15 batters that night and impressed Ryan -- the Hall of Fame pitcher and Round Rock owner -- so much that Ryan convinced the Astros to keep him in Double-A.

“That night, I’m thinking, ‘I might just be able to stay up here,’” Oswalt said.

The Astros canceled his return ticket to Florida, and Oswalt went 11-4 with a 1.94 ERA that year for Round Rock. He was in the big leagues a year later at 23 years old and went 14-3 with a 2.73 ERA as a rookie. Oswalt became one of the NL’s best starting pitchers over the next decade, winning 19 games in 2002. The Astros traded him to the Phillies in ’10 in a deal that started the team’s massive rebuild.

4.
Key fact: His 51.4 WAR with Astros is fourth to only Bagwell, Biggio and Jose Altuve

One of the most popular players in club history, Cruz played 13 of his 19 big league seasons in Houston. The outfielder retired with 2,251 career hits, 165 homers, 1,077 RBIs and 317 stolen bases. Cruz still holds the Astros’ career record with 80 triples.

Cruz led the NL in hits in 1983 with 189 and finished in the top six in the NL batting race three times: third in 1978 (.315) and '83 (.318) and sixth in '84 (.312). He was among the top 10 in the NL in RBIs three times, triples four times and stolen bases four times.

5.
Key fact: Holds club record for complete games (106), shutouts (25) and innings (2,294 1/3)

Before he was a popular broadcaster and a successful manager of the Astros, Dierker spent 13 seasons as a workhorse atop the Astros' rotation, winning 137 games in that span. Signed as an amateur free agent by the Colt .45s, Dierker made his Major League debut on his 18th birthday on Sept. 22, 1964, and struck out Willie Mays looking to end his first inning.

Dierker became the franchise’s first 20-game winner by going 20-13 in 1969 and made the All-Star team en route to being named the team’s MVP. During that season, he pitched 12 innings in a 3-2 loss to the Braves.

“That was a momentous game for me because it was the first year in Astros history we were actually a contending team in September, and that one game blew us right out of contention and seemed to launch [the Braves] on a streak that took them to the NL West title,” he said.

Dierker threw a no-hitter on July 9, 1976, in the Astrodome against the Expos. He finished his career with the Cardinals in '77 and returned to Houston to spend 18 years in the broadcast booth. From there, he was hired to manage the team in '97, and he led the Astros to four division titles in five years.
