A doping scandal involving one of baseball’s biggest stars is the latest in a series of cases in sport this year that have led to repeated calls for a tougher line on drug cheats.

New York Yankees’ Alex Rodriguez, popularly known as A-Rod, is a three-time Most Valuable Player. The 38-year-old was banned on Monday for 211 matches for not only using banned drugs “over the course of multiple years” but also acting to “obstruct and frustrate” a probe into drug abuse.
