9 wickets in the first innings — the only wicket he didn't take was Tony Lock, who dismissed the other Australian. 10 wickets in the second innings. 19 wickets in a Test. 19/90.
Lock, bowling from the other end, took 1 wicket. Every other wicket fell to Laker. In the second innings, Australia batted for 120 overs and Laker bowled 51.2 of them. He dismissed McDonald, Harvey, Miller, Craig, Mackay, Archer, Johnson, Lindwall, Gil Langley, and Ian Meckiff — the entire batting order.
At the end, Laker walked off Old Trafford with his sweater over his arm, as matter-of-factly as if he had taken a pleasant 5-wicket haul. He was asked how he felt. He said he was pleased. No cricketer has ever taken 19 wickets in a Test since, and no cricketer is likely to.
