BOSTON -- The Rangers are holding off on activating reliever Eddie Guardado off the disabled list.
Guardado has been on the DL since April 12, retroactive to April 4, with a sore left shoulder and is eligible to come off on Sunday. But the Rangers decided to wait after Guardado, who threw in the bullpen on Saturday afternoon, told them that his shoulder is still weak.
"It's getting better every day," Guardado said. "Today was great, but I still feel weak."
Guardado will take Sunday off and then throw again in the bullpen on Monday. That will give the Rangers a better indication of when he might be ready.
"I don't want to do anything stupid," Guardado said. "But I think it should be all right."
Guardado, signed as a free agent in the offseason, has made just two appearances for the Rangers this year. His absence leaves the Rangers with C.J. Wilson as their only left-handed reliever.
"He was honest with us," Rangers manager Ron Washington said. "The type of warrior he is, he might try to fight through it, but if he did that, he knows the situation he might put us in if he has a setback and we need to make a move."
