Manny Ramirez will serve as the Oakland Athletics' designated hitter in their Cactus League opener Friday.
Ramirez, who agreed to a one-year, $500,000 contract in the offseason, is permitted to play in preseason games.
Once the regular season begins, he will have to serve a 50-game suspension for violating baseball's drug policy for a second time.
Ramirez, who will have turned 40 during the time of his suspension, is batting .312 for his career. His 555 home runs place him 14th on the all-time list.
Last year, Ramirez limped to a .059 batting average in five games with the Tampa Bay Rays.
