Double world champion Shericka Jackson won the 200m on Sunday at the Jamaican athletics trials to set up a 100-200 sprint double gold bid at the Paris Olympics.
Jackson, who already captured the 100, took the 200 in 22.29secs (1.6 m/sec wind) in Kingston and will race the 100 and 200 in France.
Jackson, 26, impressed in the absence of Shelly-Ann Fraser-Pryce, who is focusing on the 100m, and Olympic champion Elaine Thompson-Herah, who is injured and did not compete.
Lanae-Tava Thomas was second in 22.34 with Niesha Burgher third in 22.39.
Without 100m stars Kishane Thompson and Oblique Seville, Bryan Levell won the men's 200m in 19.97 (1.3 m/sec).
In the 100m hurdles, Ackera Nugent won in 12.28sec (0.5 m/sec), a Jamaican record that made her the ninth-best athlete in the history of the discipline.
Nugent, 22, the 2021 junior world champion, beat Danielle Williams (12.53) and Janeek Brown (12.61) to position herself as an Olympic podium contender.
In the 110m hurdles, reigning Olympic champion Hansle Parchment secured an Olympic ticket with a third-place finish in the final in 13.19secs (0.4 m/sec) despite being beaten by Rasheed Broadbell and Orlando Bennett, both on 13.18.
Omar McLeod, the 2016 Rio Olympic champion, was fifth in 13.22secs and failed to qualify for the Olympics.
