WASHINGTON -- Triple-A Syracuse right-hander Josh Wilkie has been suspended for 50 because of use of "a drug of abuse," according to a baseball source. General manager Mike Rizzo declined to comment on Wilkie's suspension.
Wilkie was having one of the worst years of his career out of the bullpen, going 0-2 with a 4.76 ERA for the Chiefs. Wilkie is best known for getting a tryout with the Nationals with the help from former outfielder Jose Guillen. Wilkie ended up signing a free-agent contract with the team in 2006.
Triple-A Syracuse infielder Josh Johnson was also placed on the restricted list. It's not known why he was placed on the list. A career Minor Leaguer, Johnson was hitting .233 with 10 RBIs for the Chiefs.
