On Monday, Jeremy Hellickson was activated from Triple-A Durham to start against the Twins. In a corresponding move, Sonnanstine was placed on the 15-day disabled list with a left hamstring strain, retroactive to July 23.
Sonnanstine said the problem has bothered him since the Rays played the Yankees in New York on July 18.
After Monday night's game, Hellickson was sent back to Durham and Dan Johnson was activated. Which brings the question: What happens on Saturday when Sonnanstine is eligible to come off the disabled list? Rays manager Joe Maddon said a move could be made on Saturday, but he did not speculate about what that move might be.
