2023 Seattle Mariners season

The 2023 Seattle Mariners season was the 47th season in franchise history. The Mariners played their 24th full season (25th overall) at T-Mobile Park, their home ballpark in Seattle, Washington. After making the playoffs in 2022 and having a 90.2% chance to make the playoffs on September 2 while in first place in the American League West, the Mariners missed the postseason. The Mariners drew an average home attendance of 33,215 in 81 home games, the 10th highest in Major League Baseball.

The Mariners hosted the All-Star Game on July 11. Center fielder Julio Rodríguez and pitchers Luis Castillo and George Kirby were selected as All-Stars. Rodríguez also competed in the Home Run Derby.
