Shericka Jackson goes supersonic as Asher-Smith takes world 200m bronze

• Jamaican lays down second fastest time in event's history
• Shelly-Ann Fraser-Pryce takes world championship silver

Over 21.45 extraordinary seconds, Shericka Jackson flew supersonic into golden skies. Meanwhile Dina Asher-Smith found inspiration in the heavens to claim a stunning 200m bronze medal.

Stunning because, as Asher-Smith revealed afterwards, she had been knocked sideways by the death of her cherished 92-year-old grandmother Sislyn Asher, who was part of the Windrush generation, in May. Yet here she was, after a season of doubts and fears and heartache, proving once again that she is one of the world's greatest sprinters.
