Cardinals outfielder Matt Holliday, a late scratch before Game 6 of the National League championship series, was taken for a scan of his lower back during the game to determine if there was anything structural wrong with the area that had given him fits during batting practice. The magnetic resonance imaging scan of his lower back came back negative of any structural problems, general manager John Mozeliak said. The injury is localized around his muscles. Mozeliak said his status for Game 7 is uncertain. "It's nothing more than what they thought (before the MRI)," Mozeliak said after the Cardinals' 6-1 loss to the Giants on Sunday night. "It came back negative. We'll basically list him as day-to-day and see how he feels tomorrow. I wouldn't say he's a game-time decision, but we'll have an idea what he's able to do tomorrow." Holliday had been dealing with lower back discomfort headed into the postseason. He aggravated the injury on a swing Friday night in Game 5, Mozeliak said. The left fielder attempted to take part in batting practice Sunday afternoon. He was able to get in the cage and take some swings, but teammates, trainers, and manager Mike Matheny saw something was wrong. Matheny said it was clear that Holliday couldn't complete his swing without pain. "He didn't look right during BP," cleanup hitter Allen Craig said. "He really looked like he was in pain. It looked frustrating for him."
