The 28-year-old, who has just joined the Devil Rays, has been banned for 10 days for using a prohibited substance.
Sanchez has denied taking steroids and plans to appeal against the ban, which will begin immediately.
The tougher new measures were agreed between players and team owners in January after a series of allegations that hit the sport in 2004.
