Left-hander Dontrelle Willis, who left Triple-A Norfolk's game Wednesday after nine pitches, has been placed on the seven-day disabled list with a left forearm strain.
“I’ve worked hard. Maybe it’s overuse," Willis, who is being converted into a reliever, told the newspaper.
The injury does not appear to be serious.
In other minor league moves, infielder Zelous Wheeler was reassigned from Norfolk to Double-A Bowie and right-handers Miguel Gonzalez and Kyler Newby were added to the Tides' roster from extended spring training.
