Double-A prospect Williams suspended 50 games

MILWAUKEE -- Double-A Huntsville left-hander Alan Williams drew a 50-game suspension without pay Tuesday after a second positive test for a drug of abuse.

The Office of the Commissioner of Baseball made the announcement on Monday afternoon. Per terms of the Minor League Drug Prevention and Treatment Program, it did not name the substance in question. Testing in the Minor Leagues is more far-reaching than in the Majors, and included penalties for marijuana.

Williams, 23, was signed out of the independent Frontier League in May 2011. He was 0-2 with a 3.00 ERA in three starts and 10 relief appearances at Huntsville.
