Nate McLouth out at least six weeks
McLouth was placed on the 15-day disabled list last week with an abdominal strain. The operation was performed in Philadelphia on Thursday. McLouth also spent almost a month on the disabled list early in the season with a strained left oblique.
Jose Constanza, called up from the minors when McLouth went on the DL, should see more playing time.
