Lance Berkman (hip) admitted Wednesday that he's "probably still not quite ready" to return to the lineup. In addition to his hip ailment, Berkman also has chronic soreness in his right knee, which he has had operated on four times. He is taking batting practice but has yet to do any real running. "He's progressing, but it's slow," Rangers manager Ron Washington said. "We just have to let it go through the process. He'll let us know when he's ready."
