Cardinals outfielder Matt Holliday missed his second-straight game on Thursday because of back discomfort. He suffered the injury during a weight-lifting session on Wednesday. A source familiar with the incident said Holliday experienced a pull in his lower back when he lifted a 40-pound weight from a rack. "He might not be (ready) until Monday, so I don't know," Cardinals manager Tony La Russa said. "But they're not making any noises like it's something more than a few days, certainly not 15."
