Olympic 100m bronze medallist Shericka Jackson sent shockwaves through Kingston’s National Stadium on Friday with a blistering 10.77 to win the Women’s 100m on day two of the 2022 Jamaican National Senior Athletics Championships.

Jackson, who stomped her feet in joy after the race, finished ahead of NCAA Championships 100m silver medalist Kemba Nelson who ran a personal best 10.88 for second while defending double Olympic Champion Elaine Thompson-Herah was third in 10.89.

Meanwhile, 2011 World 100m Champion Yohan Blake turned back the clock to secure the Men’s title in a time of 9.85, his fastest time since 2012.

Pre-meet favorite Oblique Seville ran 9.88 for second while Ackeem Blake was third in a new personal best 9.93.

Elsewhere, Jaheel Hyde successfully defended his title as national 400m hurdles champion with a 48.51 effort to narrowly finish ahead of Kemar Mowatt (48.53) while Shawn Rowe ran 49.66 for third.

The Women’s equivalent was won by Janieve Russell in 53.63 ahead of Shiann Salmon who ran a personal best 53.82 for second. 2019 World Championship bronze medallist Rushell Clayton was third in 54.20.

Andrenette Knight, who entered the final as the third fastest woman this year with a 53.39 effort in Nashville on June 5, was leading the event after six hurdles but failed to finish the race after unfortunately clipping the seventh and falling to the track.
