The Best Players in Seattle Mariners History, Position by Position

By 4Baseball Staff · November 5, 2026 · 10 min read

An all-time Seattle Mariners team built from club career leaders, award winners and Hall of Famers, with the selection rules stated and the close calls at second base, third base and the rotation argued out.

The Seattle Mariners have never won a pennant through the 2025 season, and their all-time team is still one of the most interesting in the American League. The club began play in 1977, and the historical record shows 3,689 wins and 4,022 losses across 49 seasons. Over those years the franchise has employed four Hall of Famers who spent a decade or more in its uniform, a pitcher who won a Cy Young Award with a 2.27 earned run average and only 13 wins, and a leadoff hitter who collected 242 hits as a rookie. The standard of talent is high even where the win totals are not.

This article builds an all-time Mariners lineup, rotation and bullpen. It states its selection rules, goes position by position, and is open about the places where the data cannot settle an argument. Everything below comes from the historical record through 2025, and every total counts only what a player did with Seattle, unless the text says otherwise.

For the story of the club in order, read the history of the Seattle Mariners. For the seasons themselves, the best Mariners seasons and every October run lines up the playoff appearances in 1995, 1997, 2000, 2001, 2022 and 2025.

How the team was chosen

Four rules decide the lineup. The first is that only Seattle years count. Alex Rodriguez hit 696 home runs in his career, but only 189 of them came as a Mariner, and the question here is who was best for this franchise. Randy Johnson's 4,875 career strikeouts belong mostly to other clubs; his Seattle total is 2,162. Ichiro Suzuki is the opposite case, because his Mariners numbers are a large share of the whole.

The second rule is that peak and longevity both count. A player with 13 seasons of excellent work can beat a player with three seasons of historic work, but a three-season peak can beat a long career of competence. The third rule is that the lineup has to be legal. Edgar Martinez has a strong claim to be the best designated hitter in the history of the sport, but he cannot also play shortstop, so each position gets one starter and the DH slot goes to the best bat left over. The fourth is that awards and Hall of Fame votes are evidence, not proof. They record what voters thought at the time.

The limit that hangs over all of it is that the historical record carries no Wins Above Replacement, no Statcast and no modern defensive metrics. Where defence is the heart of the case, as at catcher or second base, the choice here rests on output, awards and reputation. WAR explained describes what the missing number measures, and some of the picks below would move if you had it.

The lineup at a glance

Center field and right field: Griffey and Ichiro

Ken Griffey is the face of the franchise and the first name on the roster. His Seattle totals are 417 home runs, 1,216 runs batted in, 1,113 runs and 1,843 hits, with 167 stolen bases. In 1996 he hit 49 home runs, and in both 1997 and 1998 he hit 56, with 147 and 146 runs batted in. He won the American League MVP award in 1997 and 10 straight Gold Gloves from 1990 to 1999. His career total across all clubs is 630 home runs, and the Baseball Writers elected him in 2016 with 437 of 440 votes.

Ichiro Suzuki belongs next to him in right field. He arrived in 2001 after years of stardom in Japan and won both the Rookie of the Year award and the MVP award that year, with 242 hits and a .350 average. In 2004 he hit .372 with 262 hits, which broke George Sisler's long-standing record of 257. His Seattle totals are 2,542 hits, 438 stolen bases and 1,181 runs, and his Seattle average is .321, the best among Mariners with at least 3,000 at-bats. He won 10 Gold Gloves from 2001 to 2010 and was elected in 2025 with 393 of 394 votes.

What do the numbers miss? Ichiro's career line is .311/.355/.402, which is a hitter who got on base by hitting singles at a rate nobody matched, with modest power and a walk rate lower than most stars. He is a good example of a player whose value is real but easy to misprice in either direction. A box score that counts hits makes him a monster; a model that weighs only on-base and slugging makes him merely excellent. Both are partly right.

Left field and designated hitter: Buhner and Martinez

Left field is not a settled spot in Mariners history, and the lineup uses it as a place for the best remaining bat. Jay Buhner hit 307 home runs for the club, drove in 951 runs and drew 788 walks, and he hit 40 or more in three straight years, 40 in 1995, 44 in 1996 and 40 in 1997; Seattle won division titles in 1995 and 1997. He was a right fielder by trade, and the left-field label is a convenience of lineup building. Raul Ibanez, who hit 156 home runs and collected 1,077 hits for the club, is the other serious candidate. Julio Rodriguez, the 2022 Rookie of the Year, has a short Seattle career so far, with 116 stolen bases and 112 home runs through 2025, and it would be premature to rank him against a career of that length.

Edgar Martinez deserves a separate argument, because a designated hitter has to fight for his reputation. He spent 18 seasons with the club and finished with 2,247 hits, 309 home runs, 1,261 runs batted in and 1,283 walks. His career batting line is .312/.418/.515. He won the Outstanding Designated Hitter award five times, in 1995, 1997, 1998, 2000 and 2001, and he won the 1995 American League batting title at .356. In 2000 he drove in 145 runs.

His Hall of Fame path shows how voters treated the position. He was on the writers' ballot for ten years, started at 195 votes of 539 in 2010 and was elected in 2019 with 363 of 425. For years, many voters declined to treat a designated hitter as a complete player. The case for him is that the DH slot is a real position in the American League lineup, and the person who hits there still has to produce, and he produced. The Mariners lineup is the best evidence: the top of it is Griffey, Ichiro, Rodriguez and Martinez, four players who each changed what the club could do.

Shortstop and third base: Rodriguez and Seager

Alex Rodriguez spent only five full seasons in Seattle, and his case is still strong. His Mariners totals are 189 home runs, 595 runs batted in, 627 runs and 133 stolen bases, with a .309 average. In 1996 he hit .358 with 215 hits, 36 home runs and 123 runs batted in, while still in his early twenties. In 1998 he hit 42 home runs at shortstop. He left after the 2000 season, so the Seattle sample is narrow.

The alternative at shortstop is J. P. Crawford, who has been the club's regular shortstop since 2019 and has drawn 412 walks, but his career is not close to Rodriguez's peak. The pick is Rodriguez because he was an outstanding player in this uniform, even if his best-known years came later and elsewhere.

Third base is Kyle Seager's, and the argument is a good test of method. Seager played from 2011 to 2021 and is fourth on the club list in both home runs (242) and hits (1,395), with 807 runs batted in and 705 runs. He won a Gold Glove in 2014. His line, .251/.321/.442, is a good player, not a star, and what makes him a Mariner great is eleven seasons of reliability. Adrian Beltre, a Hall of Famer elected in 2024, played five seasons for the club, but his best-known years came with other teams. Seager's decade-plus beats Beltre's five for this franchise, and that is the tradeoff of a franchise-only view.

First base, second base and catcher

First base is a choice between Alvin Davis and John Olerud. Davis won the Rookie of the Year award in 1984 with 27 home runs and 116 runs batted in, and finished his Seattle career with 160 home runs, 667 runs batted in and 672 walks, with a .280 average and a .380 on-base percentage. Olerud spent five seasons in Seattle and drew 418 walks, which is excellent for a short stay. The pick is Davis, as the longer and more central career.

Second base has two good answers. Bret Boone hit .331 with 37 home runs and 141 runs batted in in 2001, the season Seattle won 116 games, and again hit 35 home runs in 2003. He won Gold Gloves in 2002, 2003 and 2004 and two Silver Sluggers. Harold Reynolds, who played from 1983 to 1992, scored 543 runs and stole 228 bases and is a classic table-setter. Boone's offensive peak is far higher, and for a position that the historical record cannot grade defensively, the offensive edge decides.

Catcher is Dan Wilson, who played from 1994 to 2005 and collected 1,071 hits with the club, 88 home runs and a .262 average over his full career. These are not star numbers, but a catcher's value lives in the games he handles, and the winning teams of 1995 and 1997 had Wilson in 119 and 146 games. No other catcher appears in the club's batting leader lists. If you are interested in why catchers rarely post big numbers, how to play catcher is a good place to start.

The rotation: Felix, Johnson and three arguments

Felix Hernandez is the best pitcher the franchise has had in its sustained history. He won 169 games, struck out 2,524 batters and pitched in 419 games over 15 seasons. The wins and strikeouts are club records. His 2010 Cy Young Award came in a season when he went 13-12 with a 2.27 earned run average and 232 strikeouts in 249.2 innings, a result that voters used to ignore and then, in that year, did not. It is a hinge moment in the way baseball valued pitchers, because his win-loss record was ordinary and his run prevention was not. In 2009 he went 19-5 with a 2.49 ERA.

Randy Johnson pitched for Seattle from 1989 to 1998 and won the Cy Young Award in 1995, when he went 18-2 with a 2.48 earned run average and 294 strikeouts. In 1997 he went 20-4 with a 2.28 ERA and 291 strikeouts. His Seattle totals are 130 wins, 2,162 strikeouts and a club-record 19 shutouts. His Hall of Fame vote in 2015 was 534 of 549, and he won four more Cy Young Awards elsewhere. For peak value he is the best pitcher the club has had.

The fight is over the other three spots. Jamie Moyer won 145 games from 1996 to 2006, a lot of them in the winning seasons of 2001 and 2003, when he went 20-6 and 21-7. He was a finesse pitcher, and his 3.97 Seattle ERA is not elite, but wins at that rate are what a staff needs. Mark Langston won 74 games and struck out 1,078 in six seasons, and Freddy Garcia won 76 games with a 3.89 ERA. Hisashi Iwakuma (63 wins, 2012 to 2017) and Logan Gilbert (884 strikeouts from 2021 to 2025) are strong bench options.

The bullpen and the manager

Seattle's save leaders are Kazuhiro Sasaki with 129 from 2000 to 2003, Edwin Diaz with 109 from 2016 to 2018 and J. J. Putz with 101 from 2003 to 2008. Sasaki won the Rookie of the Year award in 2000, and his ERA of 3.14 across his Seattle career with 129 saves earns him the closer's spot. Diaz's three seasons were short but overpowering, and a reader who values strikeouts over longevity might prefer him. Saves are a flawed statistic, because they count a situation and not a skill, but they are the one record every closer shares.

The manager is Lou Piniella, who led the club from 1993 to 2002 and won 836 games against 711 losses, in 1,547 games. His teams won the division in 1995, 1997 and 2001, and wild cards in 2000, and the 2001 team won 116 games, the most wins in franchise history. Scott Servais won 680 games in nine seasons ending in 2024 and took Seattle to the playoffs in 2022, the franchise's first postseason since 2001. Three division titles and two wild-card berths before 2025 show how rare success has been, which is part of why the best seasons loom so large.

Common questions

Why is Alex Rodriguez here when he left for Texas? The rules count only Seattle years, and in those years he was one of the best players in the league. His 1996 season, with a .358 average and 215 hits, belongs to the Mariners.

Is Edgar Martinez the best designated hitter ever? No database settles that, but five Outstanding Designated Hitter awards, a .418 career on-base percentage and 363 of 425 votes in his final year of eligibility make a strong argument. The league's annual award for the position now carries his name.

Did the Mariners ever win the pennant? Through the 2025 season, no. The closest finishes are the 1995 ALCS (lost to Cleveland, 2 games to 4), the 2000 and 2001 ALCS (both lost to the Yankees) and the 2025 ALCS (lost to Toronto in seven games, 3 to 4).

Where can I read about the other AL West clubs? The Athletics article, the Astros article and the Angels article tell those stories.

How does Seattle's ballpark change the numbers? The club has played in the Kingdome and in Safeco Field, which carries the T-Mobile Park name from 2019. T-Mobile Park's guide describes how the current one plays, and the dimensions on the site's ballpark page show short foul lines of about 330 feet in both left and right.
