Feliz, who has appeared twice for the organization's rookie league team, is set to throw Thursday and Saturday for Round Rock. He was unsure what the plan is after that.
"I don't know exactly," Feliz said. "Right now I feel great and ready to go."
Feliz, who is coming back from Tommy John surgery last Aug. 1, is throwing his fastball around 94-95 mph. He'll throw one inning for the Express on Thursday night. He will likely with be a September addition for the Rangers.
Going off the plan that Rangers reliever Joakim Soria had during his rehab stint -- he was also coming back from Tommy John surgery -- Feliz has at least five more outings to go before he would considered for a callup. Soria made seven appearances before the Rangers added him to their bullpen.
He isn't thinking about next year and the question was posed whether he still sees a future as a starting pitcher. Feliz made seven starts last season before he was shutdown and eventually had the ligament replacement surgery.
"I don't know now," Feliz said. "I just try to get ready and try to help the team get ready to win."
