Boyle (elbow) is playing catch from 90 feet, MLB.com reports.
The Rays are hopeful that the right-hander will be able to throw a bullpen session by the end of April. Boyle is on the 15-day injured list due to a right elbow strain, and he may need a minor-league rehab assignment before being cleared to rejoin Tampa Bay's rotation. Fantasy managers shouldn't expect him to be available until sometime in May.
