Today Major League Baseball announced that they will establish a department of investigations, which will serve as a permanent branch devoted to investigating drug use in baseball. This is a good idea in theory, but whether or not it will be functional remains to be seen. It does seem to be a step in the right direction for baseball.
In a related story, Dodgers' second baseman/redneck Jeff Kent said that MLB should introduce a blood testing policy to detect banned substances, such as Human Growth Hormone, which cannot be detected in a urine test. I definitely agree with this, and it may happen this year. In September, MLB said that they would look into it.
