The highest individual score in three innings before Head strode to the crease was 52, and 30 wickets had tumbled in the 1 1/2 days in an almost incomprehensible start to the five-match series.
Usually a middle-order batter, Head started cautiously and took three runs from the first 14 deliveries he faced. Then he erupted, plundering an England pace attack that had skittled Australia for 132 in the first innings for a century from 69 balls. It was the third-fastest test century by an Australian, and the sixth-fastest by anyone.
He hooked, pulled, ramped, cut and clobbered 16 boundaries and four sixes to all parts of the Perth Stadium for just over two hours before he was out for 123 with Australia just 13 runs from a famous win.
“Today was just incredible, wasn’t it?” Smith said, talking about the context of the game. “That innings from Travis Head was out of this world. He just played some outrageous shots.
“Even when he shanked it, he seemed to hit it in the gap. He was kind of toying with them.”
