Giants prospect Jones suspended 100 games

NEW YORK -- San Francisco outfielder Chuckie Jones was suspended 100 games Monday after his third positive test for a banned substance. 

The Office of the Commissioner of Baseball said Jones received a 100-game suspension without pay for a third violation of the Minor League Drug Prevention and Treatment Program. The suspension is effective immediately. The 24-year-old had yet to play this season and appeared in 44 games last year following a 50-game suspension for a second positive test on April 9, 2015.

Jones was the Giants' seventh-round pick in the 2010 First-Year Player Draft out of Boonville High School in Missouri. He hit .256 with 15 homers, 66 RBIs and 17 stolen bases in 131 games with Class A Advanced San Jose in 2014. After serving his suspension last season, Jones batted .240 with four homers for Class A Augusta.

Players are typically issued a warning following a first positive test for a drug of abuse, a 50-game suspension for a second offense and 100 games for a third. Substances considered "drugs of abuse" by Major League Baseball include cocaine, marijuana, heroin, LSD, ecstasy and other opiates.

Jones is the 65th player and the fourth Giants prospect to be suspended this year for violating the Minor League drug program.
