Carroll (elbow) is starting in right field and batting third Tuesday against the Athletics, Alex Weiner of ArizonaSports.com reports.
The 25-year-old is back in the lineup as expected Tuesday after sitting out Monday's series opener due to a hyperextended right elbow. The fact Carroll is returning to the lineup so quickly and is playing the field rather than being eased back in as the designated hitter indicates the injury isn't a significant concern.
