T.R. Sullivan says that Freddy Guzman is going to be called up with Kameron Loe heads to the d.l.
Robinson Tejeda is apparently going to be brought up to start Saturday's game against Colorado, which will necessitate another roster move. Unless someone goes on the disabled list, it seems like Bryan Corey or Scott Feldman would be the primary candidates to be sent back down.
The other option might be Jason Botts...he isn't getting much playing time, and if the Rangers want to go back to a three man bench when Tejeda gets called up, Guzman would probably make more sense, given that Buck apparently isn't going to give Botts the DH job.
