The Dodgers are going for a clean sweep -- not of their Opening Day opponents, the Giants -- but of the waste water that seeped onto the Dodgers Stadium field.
Sources inside the L.A. County Dept. of Health tell TMZ Sports ... inspectors were roaming the third baseline area next to the dugout Wednesday ... checking out the disgusting mud patch left behind after Tuesday night's sewage spill.
If ya missed it, Big Blue's exhibition game against the Angels was cut short when a waste water pipeline burst, sending up a stench worse than Yu Darvish's World Series outings.
