By now I am sure you have heard of PED’s (Performance Enhancing Drugs). The recent suspension of approximately 20 major leaguers were all tied to this category. Performance Enhancing Drugs cover such things as testosterone, certain steroids, blood enhancers, etc. The list is too long to try to name all of them. If something is put in your body for any reason other than to cure some known ailment, it is probably performance enhancing. Even some things like asthma aids can be on this list. Players try to use ignorance, but they are all informed on what these materials are. The reward of a huge contract for performing above your competitors outweighs the risk of being caught. If I can get a $100,000,000 contract, I will take a chance on being caught because right now the suspension is short enough that I can afford it and my chances of getting caught have been low. This time some of these players passed their test, but the suspicion of using the substance was strong enough that they were suspended anyway. To fight the charges usually opens up more probing and the likelihood of finding more violations. Until the risk outweighs the reward, players will keep putting stuff in their bodies to get bigger, stronger, and less likely to get hurt. Keep the fight up, Commissioner Selig!
