Shericka Jackson Sets Stunning New World Lead As Elaine Thompson Herah Fumbles

• Shericka Jackson wasted no time in overtaking Sha'Carri Richardson as the fastest woman this year
• Richardson had used 10.71 seconds at the USA Championships, but Jackson clocked 10.65 seconds less than 24 hours later
• Elaine Thompson-Herah finished a surprising fifth leaving her participation in the 100 metres in limbo

Shericka Jackson broke Sha'Carri Richardson's one-day record by setting a blazing new World Lead at the Jamaican National trials on Friday evening.

Jackson clocked 10.65 seconds to become the new national champion and book her ticket to the World Athletics Championships, where she is set to attempt a double sweep.

The reigning 200 metres World Champion has a wild card for the same event in Budapest but had to dig deep to qualify for the shorter version.

Shockingly, two-time Olympic champion and the second-fastest woman in history, Elaine Thompson-Herah, finished fifth, missing out on the automatic qualification spots. Thompson-Herah will now have to wait for the Federation to make a decision on her inclusion either in the relay race or individual 100m.

Shashalee Forbes(10.96) and Natasha Morrison(10.98) also confirmed their spots in Budapest. Thompson-Herah used 11.02 seconds.

Jackson's 10.65 seconds now moves her to the top-five fastest women in history. Only Florence Grifith-Joyner(10.49), Thompson-Herah(10.54), Shelly-Ann Fraser-Pryce(10.60) and Carmelita Jeter(10.64) have run faster times than her, as figures from World Athletics indicate.

Thompson-Herah will line up against Fraser-Pryce in the 200 metres trials. The latter, a five-time 100m World Champion, did not participate in the 100m trials because she has a wild card.

Sports Brief also reported that Usain Bolt called out experts questioning his form and technique via Twitter, as trials in different countries get underway.

Jamaica and the USA, two of the most revered countries as far as sprinting goes, will select teams for the World Athletics Championships this weekend.

World champions, Fred Kerley and Noah Lyles, are expected to lead USA's team as they hunt down Bolt's stunning record of 9.58 seconds he set in 2009.
