The DMN Rangers blog reports that Kason Gabbard has been optioned to AAA and Robinson Tejeda is returning to Texas. No word yet on if he's in the bullpen or taking Gabbard's rotation slot.
Dustin Nippert has been activated from the disabled list, cleared waivers, and has been outrighted to Oklahoma. This means we now have 39 players on the 40 man roster (since Tejeda has been added), although Thomas Diamond will likely be activated from the 60 day d.l. and optioned before too long, which will bring the number to 40.
In addition, Franklyn German has opted for free agency, rather than accepting the outright assignment to AAA.
UPDATE -- T.R. Sullivan says Mathis stays in the rotation, Tejeda goes to the pen.
