Daniel Rios has been suspended 1 year by the Nippon Professional Baseball League for testing positive for a banned substance. Rios signed with the Yakult Swallows after pitching for 6 years in South Korea. He also had a stint with the New York Yankees in 1996 and the Kansas City Royals in 1998. Rios had gone 2-7 with a 5.46 ERA prior to being demoted to the minors on June 2.
Rios was initially tested on May 21st and then tested again on June 21st -- both tested revealed traces of hydroxystanozorol. He becomes the second player to positively test for a banned substance this season, and third overall.
The Swallows are investigating whether or not they will be able to cancel Rios' contract outright.
UPDATE: In watching the news right now, it sounds like Rios got some shots for some pain he was experiencing. The doctors later told him that the shots contained hydroxystanozorol. Now whether or not he's telling the truth, I have no idea, but that's his story.
This was all divulged during his press conference that took place earlier in the day.
