Belgian ace Hazard was on target twice as Chelsea earned all three points against a battling West Brom side.
The forward combined well with Olivier Giroud to stroke home the opener before striking again midway through the second half.
Victor Moses also got on the scoresheet between Hazard’s two goals, while ex-Arsenal star Olivier Giroud missed several good chances on his first start for Chelsea.
The French forward received some rough treatment from the Baggies defence, picking up a cut on the head and a knock to the calf before being withdrawn.
