Gauna Suspended for 50 Games

Oakland A's prospect Koby Gauna will be suspended for the first 50 games of the 2015 minor league season.

Reliever Koby Gauna made a strong first impression during his pro debut season last year. Unfortunately, he will have to wait to continue that momentum. Gauna was suspended for 50 games on Friday after testing positive for a second time for a drug of abuse. Gauna was the A's 20th-round pick last season and was ranked as the A's 47th-best prospect heading into this season.

Gauna spent most of his pro debut season with short-season Vermont. He saved 12 games in 12 opportunities and had a 2.08 ERA in 17.1 innings. Gauna struck-out 14 and walked two. Gauna doesn't throw particularly hard, but he has an excellent sinker and he had a 2.40 GO/AO with the Lake Monsters.

Gauna will be eligible to return to regular season action in late May.
