Updating a previous report, Holliday was held out of Sunday's lineup due to back tightness, Jim Hayes of FOX Sports Midwest reports. Holliday doesn't get many days off, so it was a bit surprising to see him held out of action with the Cardinals fighting to hang on to their division lead. It sounds like back tightness was to blame, however, so consider the outfielder day-to-day until the team provides additional information. The Cardinals open a four-game series with the Reds starting Monday, when Holliday will look to make his return.
