Jamie Moyer played an astounding 25 years in the Majors, and the crafty southpaw would spend 11 of them with the Seattle Mariners.

Alex Rodriguez only played with the Seattle Mariners until he was 25 years old, but he had already established himself as one of the most exciting players in the game.  Based on the mega-deal he signed with the Texas Rangers when the Shortstop left the Mariners, the consensus was that he was also one of the best.

The Montreal Expos made a huge (a literal 6’ 10” mistake) when they dealt a young Randy Johnson to the Seattle Mariners early in the 1989 season.  It was evident immediately that there was something special as Johnson could strike out a lot of batters, but he had control problems.  It would, however, not take long for the "Big Unit" to become one of the stud pitchers in baseball.

From Venezuela, Felix Hernandez signed with the Seattle Mariners as an Amateur Free Agent in 2002, with the hopes of following the footsteps of his idol, Freddy Garcia. 

In 2005, at age 19, Hernandez made his debut and would start 12 Games.  From there, Hernandez would begin his slow ascent to one of the best hurlers in the Game.  He would break out in 2009, with a league-leading 19 Wins, his first All-Star Game, and a second place finish in Cy Young voting.
