A tough 61-101 year saw manager Don Wakamatsu lose his job in midseason as the Mariners set a club record for the fewest runs, their 513 in 162 games making them the lowest scoring team in the Majors since the designated hitter era began in 1973.
But despite those struggles, Felix Hernandez won the AL Cy Young Award as voters recognized his sterling 2.27 ERA with 232 strikeouts in 249 2/3 innings overshadowed a 13-12 record. The Mariners also earned a pair of Gold Gloves with Ichiro winning his 10th and Franklin Gutierrez his first.
Ichiro led the Majors in hits for a fifth straight season with 214 while batting .315 with 42 stolen bases and was selected to his 10th straight All-Star Game. Cliff Lee also made the All-Star team, but wore a Rangers uniform after being traded to Texas just prior to the Midsummer Classic. Ken Griffey Jr. retired on June 2, ending his 22-year career with 630 home runs. 2010 stats »
The Mariners went 67-95 in manager Eric Wedge's first season, which featured a large youth movement as 18 rookies saw playing time. The club hung in the AL West race for 2 ½ months, sitting just a half-game behind Texas at 37-35 on June 19. But a franchise-record 17-game losing streak in July led to a 24-47 record after the All-Star break.
Felix Hernandez went 14-14 with a 3.47 ERA while earning his second All-Star berth, joined at the Midsummer Classic by rookie right-hander Michael Pineda (9-10, 3.74). The Mariners had the sixth-best ERA in the American League at 3.90, but fielded the lowest-scoring offense for a third straight year.
Ichiro saw his streak of 200-hit seasons end at 10 as he batted a career low .272 with 184 hits and didn't earn an All-Star berth or Gold Glove for the first time. But there were reasons for optimism offensively, with the midseason additions of rookie standouts Dustin Ackley and Mike Carp leading the youth movement. 2011 stats »
It might not have been a perfect season for Seattle, finishing last in the AL West with a 75-87 record, but manager Eric Wedge's second year certainly had its magical moments, highlighted by the Aug. 15 afternoon when Felix Hernandez threw the first perfect game in franchise history in a 1-0 victory over the Rays at Safeco Field.
The Mariners became the first club in Major League history to have a perfect game for and against them in the same season as they fell victim to a perfecto by Philip Humber of the White Sox on April 21. And for good measure, Seattle had six pitchers combine for a June 8 no-hitter - just the third in Mariners history until Hernandez joined the club in perfect fashion two months later - when Kevin Millwood, Charlie Furbush, Stephen Pryor, Lucas Luetge, Brandon League and Tom Wilhelmsen blanked the Dodgers 1-0 at Safeco Field.
All that pitching was apropos for a club that posted the third-best ERA in club history at 3.76, led by Hernandez's 13-9 season with a 3.06 ERA. The King notched his third All-Star bid and finished the year with a Major League-leading five shutouts.
Though Jason Vargas also stepped up with a career-best 14 wins, the Mariners struggled to keep pace in the tough AL West as they finished last in the AL in scoring for a fourth straight year. Ichiro Suzuki was traded to the Yankees in July, ending his run in Seattle after 2,533 hits in 1,844 games over 11 1/2 seasons. That signaled a further shift to a youth movement led by third baseman Kyle Seager, who topped the team in home runs (20), RBI (86), doubles (35) and games played (155). 2012 stats »
The Mariners added some offensive punch to their offense as they hit the second-most home runs in the Majors with 188, led by Raul Ibanez's 29 at age 41. Seattle finished 71-91 and manager Eric Wedge stepped down at season's end after his third year at the helm.
Felix Hernandez and Hisashi Iwakuma were outstanding at the top of the rotation and both were named American League All-Stars. Hernandez recorded his sixth straight 200-plus inning season and fifth consecutive 200-plus strikeout campaign while going 12-10 with a 3.04 ERA.
Iwakuma was even better, finishing third in the AL with a 2.66 ERA while compiling a 14-6 record in his first full year as a starter as he was named one of the league's three Cy Young Award finalists.
The offense was led by designated hitter Kendrys Morales, third baseman Kyle Seager and Ibanez, who tied Ted Williams for the most homers ever by a player age 40 or over.
There were 15 rookies among the 47 players who saw time during the season, with second baseman Nick Franklin, shortstop Brad Miller and catcher Mike Zunino all debuting and earning starting roles in the second half. Rookie reliever Danny Farquhar also took over as closer for the final two months and top prospects Taijuan Walker and James Paxton cracked the rotation in September as the club got a good look at its future. 2013 stats »
The Mariners improved by 16 wins in their first season under manager Lloyd McClendon, finishing one victory shy of tying for the second American League Wild Card berth with an 87-75 record.
Though they just missed getting into a one-game playoff with the A's for the final postseason berth when Oakland beat Texas on the final day of the season, the Mariners finished with their first winning record since 2009. Seattle finished with its second-best road record in franchise history at 46-35 and the seventh-most overall wins with 87.
Pitching was the name of the game for Seattle and Felix Hernandez was again The King of that competition as he put together a 15-6 record while leading the AL in ERA at 2.14 and striking out a career-best 248 batters. Seattle's team ERA of 3.17 was a club record and the best mark in the AL, while the bullpen's Major League-leading 2.59 ERA was the second-lowest by an AL team since 1990.
New closer Fernando Rodney set a club record with an AL-leading 48 saves and was one of four Mariners named to the AL All-Star team, joined by Hernandez, second baseman Robinson Cano and third baseman Kyle Seager. Hernandez started the Midsummer Classic for the first time, highlighting a midseason run that also included a Major League record 16 straight starts of seven or more innings while allowing two or less runs.
Cano, in his first season after signing a 10-year contract in free agency, led Seattle with a .314 batting average, while Seager had a breakout season with a team-leading 25 home runs and 96 RBIs while winning his first Gold Glove award. 2014 stats »
The Mariners took a step back with a 78-86 record, losing 11 more games than 2014 in a season that ended with the dismissal of general manager Jack Zduriencik, manager Lloyd McClendon and most of the coaching staff.
Former Angels GM Jerry Dipoto was hired to replace Zduriencik in late September and he replaced McClendon with Scott Servais the following month.
Right fielder Nelson Cruz certainly held up his end in the first season of a four-year, $57 million contract, finishing second in the Majors with 44 home runs while also leading the team with a .302/.369/.566 line and 93 RBIs. He became Seattle's first Silver Slugger award winner since Ichiro Suzuki in 2009. Felix Hernandez also had another outstanding season (18-9, 3.53 ERA in 31 starts) and both players earned AL All-Star honors.
Hisashi Iwakuma threw the fifth no-hitter in franchise history against the Orioles on Aug. 12 at Safeco Field and youngsters Kyle Seager and Taijuan Walker posted solid years, but early-season injuries to Iwakuma and James Paxton hurt the rotation. 2015 stats »
A new era of Mariners baseball was ushered in as general manager Jerry Dipoto took over the helm and hired new manager Scott Servais while making a flurry of roster changes and philosophy adjustments. The on-field results were immediate as the Mariners made a 10-win improvement to 86-76, while staying in the hunt for an AL Wild Card berth up to the final weekend of the regular season. The change went all the way to the top as CEO Howard Lincoln announced his retirement after 17 years as Nintendo of America sold its controlling interest in the club to a group of minority owners led by Seattle businessman John Stanton, who was approved as the new CEO in August.
Robinson Cano, in his third year with the club, rebounded from a difficult 2015 to hit a career-high 39 homers while batting .298 with 103 RBIs and earning his seventh All-Star selection. Nelson Cruz also had a big season as he finished second in the Majors with 43 home runs and led the team with 105 RBIs. Kyle Seager chipped in another 30 homers and 99 RBIs for a club that ranked second in the AL in home runs and third in scoring. Injuries hampered the pitching staff as four starters from the Opening Day roster missed time, including a seven-week disabled list stint by Felix Hernandez. With the King limited to an 11-8 record and 3.82 ERA, Hisashi Iwakuma led the club with a 16-12 mark. Flame-throwing rookie Edwin Diaz was a big midseason addition to the bullpen and emerged as the closer by year's end while saving 18 games in the final two months.
Iwakuma was named the team's Pitcher of the Year by the Seattle Chapter of the BBWAA, while Cano was Player of the Year and Cruz earned Unsung Hero honors. 2016 stats »
Manager Scott Servais' second year at the helm ended with a 78-84 finish after injuries largely derailed a promising season. Things never quite all fell into place for a team that wound up using 61 players - the second-most in MLB history since 1901 -- including a club-record 40 pitchers and 17 different starters.
The Mariners were minus their expected top four rotation members for much of the season. Veteran ace Felix Hernandez missed nearly four months with shoulder issues, fellow right-hander Hisashi Iwakuma sat out the final five months with similar problems, up-and-coming lefty James Paxton was sidelined two months by two different injuries, and key offseason addition Drew Smyly never got started after hurting his elbow during Spring Training.
General manager Jerry Dipoto made numerous moves to keep the club in contention for a Wild Card berth, acquiring starters Mike Leake, Erasmo Ramirez and Marco Gonzales during the season and also picking up All-Star first baseman Yonder Alonso from the A's for the stretch run.
Designated hitter Nelson Cruz led the league in RBIs with 119 and slugged 39 homers while earning his fifth All-Star berth and second Silver Slugger Award, while Robinson Cano was an All-Star for the eighth time in a season that saw both Cruz and Cano pass 300 career home runs and Cano surpass 500 doubles.
When healthy, Paxton put together a breakout campaign as he went 12-5 with a 2.98 ERA, while shortstop Jean Segura batted .300 after being acquired from the D-backs in the offseason. Catcher Mike Zunino took a big step forward by hitting .251 with 25 homers and rookies Mitch Haniger and Ben Gamel provided a boost of youth and athleticism in the outfield. 2017 Stats >>
The Mariners put together an 89-73 record that stood as the club's best season since 2003, including a sensational season by 24-year-old closer Edwin Diaz, whose 57 saves tied for the second-most in MLB history.
Right fielder Mitch Haniger also had a breakout season and joined Diaz, shortstop Jean Segura and designated hitter Nelson Cruz as American League All-Stars. James Paxton threw the sixth no-hitter in franchise history and Marco Gonzales led the team with 13 wins in his first full season as a starter.
The Mariners mastered the art of the close win, going 14-1 in extra-inning games and 36-21 in one-run decisions, helped by Diaz's MLB record 27 saves when entering with a one-run lead. Seattle's record when Diaz entered with a lead was a remarkable 66-0.
General manager Jerry Dipoto undertook what was termed a "stepback" season as the Mariners employed 21 players who made their Major League debuts while going 68-94 and finishing fifth in the AL West.
The club opened the year by sweeping the A's in a two-game Opening Series in Tokyo and was 13-2 in mid-April as the offense opened on high gear. The Mariners set a Major League record by homering in each of the first 20 games of the season and became the second team in MLB history to hit a home run and double in 20 straight game at any point in a campaign. But that pace was impossible to keep up and the youth and roster turnover eventually caught up with a club that also set an MLB record for most players used in a season (67) as well as pitchers (42).
First baseman/designated hitter Daniel Vogelbach earned his first AL All-Star berth with a hot first half, center fielder Mallex Smith topped the Majors with 46 stolen bases and left-hander Marco Gonzales led the pitching staff by going 16-13 with a 3.99 ERA in 34 starts. Outfielder Kyle Lewis, one of the many rookies showing promise for the future, became the first player in MLB history to homer in six of his first 10 career games as a September callup.
