Ken Griffey Jr.

When Ken Griffey Jr. announced his retirement from Major League Baseball, it was a momentous and bittersweet occasion. On one hand, Mariners fans would lament the loss of their superstar outfielder, who was indispensable to Seattle's lineup for many years, before stints in Cincinnati and one season in Chicago. On the other hand, it provided fans an opportunity to reflect on just how impactful his career was on Major League Baseball, and fans were grateful he ended his career where it started: Seattle.
