Season summary The Mariners spent most of the season in third place in the American League West, trailing the playoff-bound Houston Astros and Oakland Athletics. They held a Wild Card position in early September, before losing 12 out of 17 games. They won their final four games but finished just outside of the playoffs.

Ace Félix Hernández was named the American League (AL) Player of the Week for June 2–8 and Pitcher of the Month for June. He struck out a career-high 15 batters on June 8.

Kyle Seager won two Player of the Week awards as well as a Gold Glove Award at third base.

Hernández and second baseman Robinson Canó started the All-Star Game, with Seager and closer Fernando Rodney also playing.

Hernández led the AL in earned run average (ERA) and walks plus hits per inning pitched, and Rodney led the majors with 49 saves, a franchise record at the time. Mariners relievers had a 2.59 ERA, lowest in the majors.

General manager Jack Zduriencik received a contract extension in August, though he and manager Lloyd McClendon would both be fired after the team underperformed in 2015.
