Boxberger (oblique) was activated from the 15-day disabled list Friday, Marc Topkin of the Tampa Bay Times reports.
The right-handed reliever has battled oblique issues for most of the season, but his recent rehab assignment gives optimism that those problems are behind him now. He made it through four separate appearances and even ramped up to 18 pitches on Tuesday. Provided he can stay healthy, he'll be a much-needed stopper in the back end of what has been a bottom tier bullpen this season. That said, Alex Colome will remain as the Rays' closer in all likelihood.
