According to Evan Grant, a source is saying that the Texas Rangers will continue the revolving door in their bullpen today, with Ryan Tucker to be called up from AAA Round Rock.
Tucker is a righthanded pitcher claimed off of waivers from the Florida Marlins last October, in a move that required the Rangers to designate Rich Harden for assignment to clear room for Tucker on the 40 man roster.
Tucker was later waived by the Rangers, cleared waivers, and was outrighted, so he is not on the 40 man roster, and a move will have to be made to clear a 40 man roster space for him.
The speculation is that Darren O'Day, who has been troubled by a hip injury, will go to the 15 day disabled list to clear a space on the 25 man roster for Tucker.
