TOKYO — J.D. Drew remained out of the lineup for the second straight game Wednesday, sidelined by a sore lower back.

Brandon Moss, the unlikely hero of the opener, was back in right again.

“It didn’t get worse,” said manager Terry Francona of Drew’s condition, “but as far as playing, no. We don’t want to take a step backwards.”

Drew first felt a twinge during batting practice before Tuesday’s game.

“It had tightened up and he was able to swing (before gametime),” said Francona. “But he just couldn’t run.”

The Sox are concerned about the 10-hour trip to Los Angeles, which they began immediately after the game ended, and the effect it will have on Drew’s back.

“I don’t know that that is the best thing for it,” said Francona, “but we’ll do what we can.”
