TOKYO (Reuters) - Fuelled by the three individual 100 metre medallists, Jamaica surged to an emphatic win in the women's 4x100m relay on Friday, posting a national record 41.02 seconds to finish well clear of the United States and Britain.

Elaine Thompson-Herah, who now has all three available sprint golds at Tokyo, Shelly-Ann Fraser-Pryce and Shericka Jackson delivered again, after Briana Williams had done her job on the opening leg.
