Red Sox put CF Cameron back on DL

The Boston Red Sox put center fielder Mike Cameron back on the 15-day disabled list Monday and recalled outfielder Daniel Nava from Triple-A Pawtucket.
Cameron has been playing through an abdominal injury for most of the year. He missed 34 games when he went on the DL early this season.
''It was being apparent it was a struggle. He has been battling it unbelievably. I don't know how he was,'' Red Sox manager Terry Francona said before the game against Cleveland. ''We're going to put him on the disabled list, get him some rest and see how he does. If that doesn't do it certainly surgery's the next option.''
If Cameron does need surgery, Francona said it would end his season.
''I think there were times he was willing himself to try and go out there to help us win,'' Francona said. ''I don't think people realize what he was going through.''
Limited to just 48 games this season, Cameron has a .259 average with four homers 15 RBIs.
Nava became just the second major league player ever to hit a grand slam on the first pitch of his initial big league at-bat against Philadelphia on June 12.
The switch-hitting Nava batted .286 with that one homer and 16 RBIs in 29 games before he was sent down on July 22.
Second basemen Dustin Pedroia, sidelined with a a broken left foot since June 26, has been running, but the club would like to keep him from doing too much. The 2008 AL MVP has already been hitting and taking grounders.
''Until that pain is very minimal, he has to keep a tight rein on it,'' Francona said.
