A muscle behind Ken Griffey Jr.'s right knee was still tight on Monday, forcing him out of the Cincinnati Reds' starting lineup for the fifth straight game. Griffey ran on a treadmill for 12 minutes. He said the leg felt better, but it still tended to tighten. Griffey has never had a problem like this one. "It's just a knot," Griffey said. "They rub it out, it comes back."
