As expected, the Rays have placed Jeff Niemann on the disabled list after he left Wednesday’s start with a strained back.
There’s no timetable yet for his return, but Niemann told Marc Topkin of the St. Petersburg Times that the injury “is very frustrating.”
According to Steve Wiseman of the Durham Herald Sun the Rays are replacing Niemann on the roster by calling up outfielder Brandon Guyer from Triple-A. Guyer, who was acquired from the Cubs in the Matt Garza trade and is hitting .356 with six homers and a 1.018 OPS in 28 games at Durham, was informed of the call-up last night but an official move hasn’t been announced.
Not replacing Niemann with another pitcher signals that the Rays will likely slide Andy Sonnanstine into his rotation spot. Sonnanstine has plenty of past experience as a starter, but it comes with a 5.33 career ERA in 76 starts and he’s been far more successful as a reliever.
