Quick hits: Cummins goes big as Maddinson makes manic cameo

Pat Cummins's explosive knock pushes Australia clear, Keshav Maharaj produces some magic in his follow-through and Steve Smith doesn't join his teammates in the field. Here are the quick hits from day four of the first Test between Australia and South Africa . Nic Maddinson hooked the first ball of the innings for four, so it was no surprise that he got a move on when day four began with Australia needing quick runs to set up a victory. He hit two boundaries in his first three balls faced, but both were off the edge.
