Olympics-Athletics-Jackson out of 200m after rookie heats blunder
Jamaica’s Shericka Jackson will not be able to add to her bronze from the 100 metres after a terrible error in the heats of the 200 on Monday, where she eased up too much and was overhauled on the line to finish fourth. Jackson, third-fastest in the world over the distance this year, did not bother to glance across and almost came to a stop as Italy’s Dalia Kaddari slipped four-thousandths of a second in front of her to snatch the third automatic slot. There were no such problems for her two compatriots in the 100m clean sweep as Elaine Thompson-Herah and Shelly-Ann Fraser-Pryce advanced safely through.
