DeLauter has been scratched from Monday's starting lineup against the Angels due to left hamstring tightness, Tim Stebbins of MLB.com reports.
DeLauter was initially penciled into the starting nine in the DH slot, but he was replaced after it was reported that he's still dealing with some nagging hamstring tightness, which is an issue that forced him to miss three games last week in a series against the Giants. He can be considered day-to-day until further notice.
