Ramirez (thumb) was activated from the injured list Tuesday, Marc Topkin of the Tampa Bay Timesreports.
Ramirez made it through a rehab game Sunday without issue, and that was all the Rays needed to see before adding him back to the roster. Ramirez is hitting .329 and owns an .825 OPS on the season, so it seems likely he will resume his role as the Rays' regular designated hitter.
