Shane Victorino left tonight's game against the Los Angeles Dodgers after his at-bat in the top of the seventh inning because of lower back stiffness.

"I felt it in BP today," he said.

Victorino said he doesn't think it's serious, and hopes it won't prevent him from playing in tomorrow night's game.

"I hope not," he said. "But we'll see. I think it happened yesterday. I don't know when."
