Yarbrough (groin) was activated from the 10-day injured list and is starting Tuesday against the Athletics, Neil Solondz of the Rays Radio Network reports.
The left-hander is back from the injured list as expected and will make his season debut after landing on the shelf with a groin injury April 10. Yarbrough was built up to 59 pitches in his final rehab start with Triple-A Durham last week, so he'll likely be limited to around 70-to-80 pitches Tuesday.
