The Seattle Mariners 1986 season was their tenth since the franchise creation. They were seventh in the American League (AL) West with a record of 67–95 (.414), the worst record in the league and second-worst in the majors.
At Boston's Fenway Park on Tuesday, April 29, 23-year-old Roger Clemens struck out 20 Mariners, a new major league record. The game was scoreless through six innings, and the Red Sox won 3–1.
Manager Chuck Cottier was fired in May. Marty Martínez managed one game as interim manager before Dick Williams became the manager.
Jim Presley represented the Mariners in the All-Star Game. Mark Langston led the AL with 245 strikeouts, and John Moses tied for the league lead with 18 times caught stealing.
