Swansea continued their fine form at home by routing hapless West Ham at the Liberty Stadium.
Ki Sung-Yeung opened the scoring with a tidy effort from range although Adrian could have done better with the low shot into the bottom corner. Mike van der Hoorn then doubled the advantage with a stooping header, taking advantage of static Hammers defending.
Things went from bad to worse for David Moyes' side as Andy King added the third from a rebound after the break and Jordan Ayew scored from the spot. Michail Antonio grabbed one back but it was a consolation.
