In the 1990s, the Seattle Mariners had one of the most talented lineups in Major League Baseball. Three players from the core of those teams hit more than 300 home runs each in their tenures and comprise three of the top five Seattle Mariners all-time home run leaders.
1. Ken Griffey Jr.: 417 home runs
Arguably the best player in baseball during his prime, Ken Griffey Jr. is the Seattle Mariners all-time home run leader. Griffey was a perennial All-Star center fielder with the Mariners as one of the best offensive and defensive players in the Majors. The MVP Award winner had six nonconsecutive 40-plus homer seasons in Seattle, interrupted only by the strike-shortened 1995 season. Ken Griffey Jr. holds the five highest single-season home run totals in team history, according to Baseball Reference, including a pair of 56 home run seasons in 1997 and 1998.
2. Edgar Martinez: 309 home runs
One of the best pure designated hitters in baseball history, Edgar Martinez ranks second on the Seattle Mariners all-time home run leaders list. Martinez was a terrific all-around hitter with great a batting average, on-base skills, and power. He twice led the American League in average and topped all hitters in on-base percentage three times while posting eight 20-plus home run seasons. The seven-time All-Star had his career year in 2000 when he hit 37 homers and led the AL with 145 RBI.
3. Jay Buhner: 307 home runs
An All-Star right fielder and big time run producer in his prime, Jay Buhner is one of the Seattle Mariners all-time home run leaders. Buhner developed into a major power threat in Seattle, causing Frank Costanza to chide George Steinbrenner for the trade that sent him there. From 1995 to 1997, he crushed 40-plus homers and drove in 100-plus RBI in each season. He had his career year in 1996 with 44 home runs and 138 RBI to reach his only All-Star team.
4. Alex Rodriguez: 189 home runs
Spending his developmental years in Seattle, Alex Rodriguez spent his first seven Major League seasons with the club and ranks fourth among the Mariners all-time home run leaders. Rodriguez finished his tenure in Seattle with three straight 40 home run seasons, becoming a league leader in the category after leaving the Mariners to sign with Texas. For his career as a whole, Rodriguez has hit a total of 604 home runs in 17 seasons.
5. Alvin Davis: 160 home runs
First baseman Alvin Davis spent eight of his nine Major League seasons in Seattle to rank fifth among the Mariners all-time home run leaders. Davis had three 20-plus homer seasons, the first of which came in 1984 when he hit 27 and won the AL Rookie of the Year Award. He topped out at 29 home runs in 1987.
