Ruiz (known as "Chooch" by fans and teammates) was today suspended for 25 games by Major League Baseball. He has apparently violated MLB's performance-enhancing drug policy.
Adderall is an amphetamine commonly used to control attention deficit hyperactivity disorder (ADHD). But Adderall is also classified as a banned stimulant under MLB's policy.
Adderall is not considered a steroid. This suspension reportedly results from Ruiz's second positive test for the stimulant.
