The 1996 Seattle Mariners season was the 20th season in franchise history, and the team was the runner-up in American League (AL) West, with a record of games behind the champion Texas Rangers. The Mariners led the majors in runs (993), doubles (335), runs batted in (954), and slugging percentage (.484), but the pitching staff had the highest earned run average (5.21) in team history, later surpassed in 1999. Four Mariners scored at least 100 runs and drove in at least 100 runs. The May 2 game against the Cleveland Indians was suspended following an earthquake at the Kingdome and completed the following day. In their game against the Kansas City Royals on May 11, the Mariners set a franchise record of 12 extra-base hits.
The Mariners were one of four AL teams that played only 161 games in 1996. A three-game series in Cleveland in September was shortened to a two-game doubleheader after the Friday night game was declared unofficial after a rain delay.
The Mariners traded away future Hall of Famer David Ortiz in September to complete a trade to acquire former All-Star Dave Hollins, who left the team after the season.
Offseason November 29, 1995: Mike Blowers was traded by the Mariners to the Los Angeles Dodgers for Willis Otañez and Miguel Cairo. January 23, 1996: Aaron Small was selected off waivers by the Mariners from the Florida Marlins. January 29: Small was selected off waivers from the Mariners by the Oakland Athletics. March 25: Ricky Jordan was purchased by the Mariners from the California Angels.
