Davis will bat fifth as the designated hitter in Tuesday's game in Tampa Bay, MASN's Roch Kubatko reports. After serving the final game of his suspension on Opening Day, Davis will make his season debut against Rays right-hander Nate Karns, who has just five big-league starts to his name. Davis had a mediocre spring in the wake of his disappointing 2014 campaign, slashing .250/.313/.450 over 60 at-bats. He's been durable over the past few seasons, and he was approved for an exemption to take Adderall again.
