Wandy Rodriguez will start for the Texas Rangers Friday, according to Jared Sandler on Twitter. He will be replacing scheduled starter Ross Detwiler, who will apparently be moving to the bullpen.

Detwiler was acquired this offseason from the Nationals for Chris Bostick and Abel de Los Santos, with the plan being to have Detwiler be the fifth starter. He got a battlefield promotion to #3 starter with the injuries to Yu Darvish and Derek Holland, but has been awful in his three starts this year. Apparently, the Rangers have seen enough to decide he is better suited to the role of bullpen lefty.

Wandy coming up will necessitate both a 25 man roster move and a 40 man roster move. Nick Tepesch can be moved to the 60 day d.l. to free up a 40 man roster spot, but Texas could opt to DFA Logan Verrett or Stolmy Pimentel instead, which would free up a 25 man and a 40 man spot.

It remains to be seen what Texas will do with their fifth starter slot. They don't need a fifth starter until April 28, and I had assumed Wandy would be taking that role. However, with Detwiler going to the pen, we could see Anthony Bass get a shot. Alternatively, Anthony Ranaudo, Luke Jackson, and Chi Chi Gonzalez are minor league possibilities.

UPDATE -- Evan Grant says Detwiler isn't going to the pen, but is going to get some extra time before he starts again to do work on the side.
