Iwakuma re-signs with Mariners

Right-hander Hisashi Iwakuma has agreed to a minor-league contract with Seattle, keeping him with the only organization for which he has pitched in the majors. Iwakuma, 36, made only six starts last season because of shoulder problems that caused him to go on the disabled list in May. Iwakuma had right shoulder-debridement surgery Sept. 27 and is expected to start throwing in late February or early March.

Tampa Bay claimed infielder Micah Johnson on waivers from the Giants. Johnson was designated for assignment last week. Infielder Orlando Calixte, also designated for assignment, cleared waivers, and was sent outright to Triple-A Sacramento.
