In what could be MLB's answer to the Kevin & Pat Williams case, J.C. Romero has been suspended for 50 games for taking a supplement he believed was legal.
Phillies (and former Twins) reliever J.C. Romero has been suspended for 50 games for a violation of MLB's drug policy. However, this is not exactly a straightforward case - Romero purchased the supplement at a GNC, and at the time of his positive test, MLBPA had assured players that any over-the-counter supplement purchased in the US was acceptable. Romero also had it checked by two separate nutritionists, although he did not call the MLB drug hotline. After he was notified of the positive test, he quit taking all supplements, and another test on October 1 confirmed that the banned substance was out of his system during the Phillies' championship run.
It's likely that Romero will challenge the suspension in court, and it would not at all shock me to see a situation similar to what happened with the Vikings' Kevin and Pat Williams this year - they tested positive for substances in supplements they had been told were legal, and a judge prevented the league from imposing the suspensions until he could make a decision on the case.
Interesting note about Romero's appeal hearing: He was told that if he admitted guilt, he could have a 25-game suspension instead of 50.
