The Mariners have some of the best prospects in the league. Here is the different Levels:
Elite- Carlos Triunfel, Michael Wilson, Mitchell Moreland, and Phillipe Aumont, Michael Pineda
Good- Juan Ramirez, Luis Valbuena, Michael Saunders, Matt Tuiasosopo, Doug Fisters, and Greg Halman
Those are the ones projected to be good and Elite. When looking back at the 2004 predictions all of the top 5 are now Mariners and are good becoming Elite. Expect these players to be coming up in 2010-2012.
