The Arizona Fall League kicks off in early October, and once again the M's will send several prospects to play for the Peoria Javelinas.
MLB announced some *preliminary* rosters today; often, one or two players will get substituted, and there are still several 'TBA' roster spots (two from the M's).
What we know now is that the M's are sending Gregory Halman, Joe Woerman, Adam Moore, Justin Thomas, and Gaby Hernandez.
Other big names on the Javelinas include CF Austin Jackson of the Yankees and "3B" Mat Gamel of the Brewers.
The battle for CF supremacy between Halman and Jackson will be great to see. Halman turns 21 today and Jackson is 21 as well.
The biggest name in the league is probably Matt Wieters of the Orioles, the likely MiLB player of the year. He and Jackson played in the Hawaii Winter Baseball League last year.
