2019 Seattle Mariners season

The 2019 Seattle Mariners season was the 43rd season in franchise history. The Mariners played their 20th full season and 21st overall at the newly renamed T-Mobile Park, their home ballpark. The Mariners extended the longest active playoff drought in the four major North American professional sports, failing to make their first postseason appearance since 2001. The Mariners started the season with a 13–2 record, their best start in franchise history. However, they went 55–92 thereafter, finishing last in the American League West for the first time since 2012 and missing the playoffs.

With the Washington Nationals winning the World Series, the Mariners became the only MLB franchise to have never played in the World Series. The Mariners also set a then-MLB record by using 69 different players during the regular season, which would stand for five years before being broken by the 2024 Miami Marlins, tied by the Baltimore Orioles in 2025, and broken by the Atlanta Braves in the same year.

Two future Mariners Hall of Famers played their last game in 2019. Ichiro Suzuki retired after the second game of the season, part of a two-game series held in Tokyo, Japan. Félix Hernández made his final start in September, earning a win.

Offseason

General manager Jerry Dipoto embarked on a "step back" plan that made the team less competitive in 2019. Veterans, including Robinson Canó, Edwin Díaz, James Paxton, and Mike Zunino were traded, which led to 21 players making their MLB debut during the season.

• November 8, 2018: Traded Mike Zunino, Guillermo Heredia, and Michael Plassmeyer to the Tampa Bay Rays for Mallex Smith and Jake Fraley.
• November 9: Signed Dylan Moore as a free agent.
• November 19: Traded James Paxton to the New York Yankees for Justus Sheffield, Erik Swanson, and Dom Thompson-Williams.
• November 30: Traded Alex Colomé to the Chicago White Sox for Omar Narváez.
• December 3: Traded Robinson Canó, Edwin Díaz, and cash to the New York Mets for Jarred Kelenic, Jay Bruce, Anthony Swarzak, Justin Dunn, and Gerson Bautista. Also, the Mariners traded Jean Segura, Juan Nicasio, and James Pazos to the Philadelphia Phillies for J. P. Crawford and Carlos Santana.
• December 5: Tayler Scott signed as a free agent.
• December 13: Traded Santana and cash to the Cleveland Indians. Received Edwin Encarnación and a 2019 competitive balance pick from Cleveland and cash from Tampa Bay.
• December 21: Received Domingo Santana in a trade with the Milwaukee Brewers, trading Ben Gamel and Noah Zavolas.
• January 1, 2019: Yusei Kikuchi signed a four-year, $56 million contract.
• January 10: Tim Beckham and Corey Gearrin signed as free agents.
• January 21: Received Shed Long Jr. in a trade with the Yankees for Josh Stowers.
• January 27: Hunter Strickland signed a one-year, $1.3 million contract.
