It was at a quarter to midnight that Anthony Joshua turned out the lights on Robert Helenius. Several minutes later, they finally came back on.
The right hand came out of nowhere, hidden behind a pair of feinted jabs, and it turned the tide on a wave of boos in the O2 Arena, after the crowd had seemed to turn on Joshua. The Briton, 33, has been accused for some time now of being gun shy, but when he finally found the trigger on Saturday, he throttled it.
