It turns out former KIA pitcher Ricardo Rodriguez was not let go due to injury. He was let go because he was caught doping. The article doesn't state what he was caught with, but it probably wasn't Flintstones chewable vitamins. The article claims he was given a 10-game suspension, but I'm fairly certain he's been released.
This is the first time a player(non-Korean or Korean) has been caught using PEDs. The KBO started mandatory testing of non-Korean ballplayers last year and has random testing for Korrean players. I still can't believe no one looked in Danny Rios' locker during his, erm, improbable run in 2007. He was caught and given a 1-year suspension from the NPB for PEDs in 2008.
