Milwaukee prospect Jeffress is sending his career up in smoke.

Jeffress will serve a 100 game suspension.
The man with a 100 mile-per-hour heater is going to be serving a 100 game suspension.
Jeremy Jeffress, the Milwaukee Brewer’s first round pick in 2006 and the organization’s fourth best prospect according to Baseball America, recently tested positive for a “substance of abuse.” However, it wasn’t for the kind of substance we’re used to hearing ballplayers get suspended for these days…
Last Friday, Jeffress tested positive for marijuana. The failure is not Jefress’ first transgression; in 2007, he served a 50 game suspension for the same reason. While scouts rave about Jeffress’ natural stuff, his makeup has always been in question.
Jeffress’ repertoire includes a fastball that often touches 100, an 11-5 curveball, and a developing changeup. He’s been pegged as a future closer, despite being only 21-years-old and extremely raw.
Jefress, however, may never get the chance to prove what he can do in the major leagues. In accordance with Major League Baseball’s drug policy, the youngster is one positive test away from a lifetime ban.
Three strikes, you’re out.
In an organization that is sorely lacking in reliable arms, Jeffress would have most likely have gotten his first taste of the show in September.
