An All-Star for three of his four seasons as a Seattle Mariner, Nelson Cruz provided substantial power numbers for his duration in the Emerald City.

If you have the nickname of "Mr. Mariner," it stands to reason that the player in question is an important player in franchise history.

Bret Boone would make history as the first-ever third-generation Major League Baseball player when he debuted with the Seattle Mariners in 1992. 

Mark Langston was a second round pick in 1981 and would debut with the Mariners in 1984, where he had a stellar rookie campaign.  The product of San Jose State went 17-10 and would lead the AL in Strikeouts with 204.  He was the runner-up to the Rookie of the Year, coincidentally losing to his teammate, Alvin Davis.
