First-half goals from Jack Collison, Junior Stanislas and Carlton Cole saw Gianfranco Zola’s side pull away from the lower echelons of the table as the visitors’ shoddy defending was punished.
Guillermo Franco made it four shortly after half-time, with substitute Luis Jimenez adding a fifth with the hosts’ second penalty as Burnley endured a torrid afternoon and their pitiful away record was further exacerbated.
Steven Fletcher then netted a consolation brace within six minutes to reduce the deficit as West Ham’s defence were seemingly crippled with complacency, but the damage had already been inflicted.
Steven Caldwell was shown a straight red for hauling down jet-heeled substitute Zavon Hines in stoppage time, but it had little bearing on an already emphatic result – as did Chris Eagles’s tap-in a minute later.
