Major League Baseball announced 50-game suspensions for two minor league players, including one who had just recently had his lucrative contract voided.

Earlier this week, MLB announced that it had voided the seven-figure deal that Dominican third baseman Duanel Jones had signed with the Giants. Now, they state that Jones has been suspended for "violating the minor league drug prevention and treatment program," providing no further details. His 50-game suspension will take effect if he signs with another team.

Marlins first baseman Adam Kam signed in August as Florida's 50th-round pick and played in two games in the Gulf Coast League, going 0-for-1 with a walk. A product of Douglas High in Parkland, Fla., the 18-year-old tested positive for the performance-enhancing substances Boldenone and Boldione.
