Royals pitcher Sidney Ponson tested positive for a stimulant during the World Baseball Classic and has been banned from international competition for two years.
Major League Baseball will not suspend Ponson. Under the drug rules, he will be treated as a first-time offender and is subject to a medical review and fine.
The 32-year-old Ponson pitched well for the Netherlands last March in the WBC and later signed with Kansas City. He is 1-5 with a 7.27 ERA for the Royals and is on the disabled list because of a strained right elbow.
The International Baseball Federation said Ponson tested positive for Phentermine. Chicago Cubs catcher Geovany Soto tested positive for marijuana at the WBC.
