RIO DE JANEIRO (Reuters) - Jamaica's Elaine Thompson completed a memorable Olympic sprint double on Wednesday after storming to victory in the women's 200 metres final, blowing away the field with a season's best run of 21.78 seconds.

The 24-year-old 100m champion beat pre-race favourite Dafne Schippers of the Netherlands, who ran her fastest time of the season in the final but had to settle for silver.
