After the recent discovery of a 125 GeV Higgs-like particle at the Large Hadron Collider (LHC), it is crucial to examine its role in unitarizing high energy WLWL scattering, which may reveal its possible deviation from a Standard Model Higgs. We perform an updated study on WW scattering in the semileptonic channel at the LHC, improved by the recently developed W jet tagging method. The resultant statistical significance of a strongly interacting light Higgs model is about 20% larger than that based on the conventionally gold-plated dileptonic channel, while 200% more signal events are retained. The excellent sensitivity to the anomalous Higgs-W boson coupling makes semileptonic WW scattering an important complement to precision measurements at the Higgs resonance.
