The 1993 Seattle Mariners season was their 17th since the franchise creation. The team ended the season finishing fourth in the American League West, finishing with a record of .500. It was the franchise's first full season under the ownership of Nintendo president Hiroshi Yamauchi, with team chairman John Ellis representing him. During the 1993 season, Randy Johnson set a club record with 308 strikeouts. It was also the first season he walked less than 100 batters. The previous fall, the team also introduced a new logo, team colors and uniform set for this season that remain the team's current look to this day (with slight adjustments made in 2015).
