MILWAUKEE -- One of the Brewers' top pitching prospects has served his time and will be back on the field this week.

Right-hander Jeremy Jeffress, Milwaukee's first-round pick in the 2006 First-Year Player Draft, will be reinstated from a 50-game suspension on Thursday and is scheduled to pitch that night for Class A Brevard County in Viera, Fla. That's assuming the wildfires in Florida do not alter the baseball schedule.

Jeffress, a 20-year-old right-hander from rural Virginia with a 100-mph fastball, went 9-5 with a 3.13 ERA last season for Class A West Virginia before he was suspended for testing positive for a "drug of abuse." He also reportedly failed team-administered tests as recently as last fall, and admitted in February to having a problem with marijuana.

"Baseball is a game I love. This is what I want to do for a living," Jeffress told the Milwaukee Journal Sentinel in February. "I had a problem. I've been to rehab to get it straight. I'm not ashamed that I've been in rehab. I went there to get help. It's something that helped me."

The Brewers drafted Jeffress with the 16th overall pick in the 2006 Draft and gave him a $1.55 million signing bonus. Under baseball's tougher drug testing rules, he would be suspended 100 games for his next positive test, then would be kicked out of the game should he fail another after that.
