Rays activate RHP Sonnanstine, demote Thayer

Tampa Bay Rays have activated right-hander Andy Sonnanstine off the
15-day disabled list and optioned right-hander Dale Thayer to Triple-A

Sonnanstine will start against
Toronto on Sunday in place of right-hander Jeff Niemann, who has a sore
shoulder. It will be the first start of the season for Sonnanstine, 2-0
with a 4.22 ERA in 30 relief appearances.

Sonnanstine went on the disabled list last Sunday, retroactive to July 23, with a strained left hamstring.

Niemann, 10-3 with a 3.12 ERA in 22 starts, felt pain after beating
Minnesota on Tuesday and was still sore after playing catch Saturday.
Manager Joe Maddon said he hoped Niemann would only miss one start.

Tampa Bay announced the moves after Saturday’s 17-11 loss at Toronto.
