Danny Rios of the Yakult Swallows is served with a one-year suspension for positive steroid tests in May and June. He is the third player to be suspended under Nippon Pro Baseball’s steroid policy (following Rick Guttormson and Luis A. Gonzalez) and the second to be suspended for a year. Rios was only 2-7 a year after having won the Korea Baseball Organization MVP award. The KBO never tested Rios for steroids when he pitched in that league. Rios, like Gonzalez, played in the majors before going to Japan.
