Those suspended are:
Fernandez, a 20-year old infielder for the GCL Astros, has been in the system since the 2010 season. He only played in 23 games this season for the organization, hitting .236/.299/.360 between Tri-City and the GCL.
Martinez, a 1B/DH, was the Astros' 36th Round pick in the 2012 draft out of Florida International University. In 59 games for Tri-City this season, he hit .225/.291/.413 with 11 homers in 237 plate appearances.
D'Andre Toney, a 21-year old outfielder, was the player to be named later in the Bourgeois/Quintero trade (that also brought back Kevin Chapman) with Kansas City. He hit .340/.432/.587 in his pro debut for Kansas City in the Arizona League, and has struggled with the Astros since, posting a .677 OPS in 2012 and a .641 OPS in 2013, hitting .219/.290/.352.
I'll let Morgan Ensberg close it out:
Just throwing this out there... What are we supposed to think when you get popped for a drug test when you know it's coming?
