Shericka Jackson ran the fourth fastest ever 200m at the Brussels Diamond League on Friday but the 35-year-old world record of polarising American Florence Griffith-Joyner remains frustratingly out of reach.
Jamaican sprinter Jackson, 29, clocked 21.48sec (wind: +0.2 m/s) and now holds three of the four fastest times over the distance of 21.41sec, 21.45 and Friday's victory.
However, the 21.34sec run by Griffith-Joyner at the 1988 Olympics remains the gold standard.
"I'm very happy with my race. I really felt good, I'm convinced that this record is coming, that I'm getting closer to it," said the double world champion.
"It's been a good season. I hope to get one more victory and get closer to this record," added Jackson who will try again to break the world record at the season-ending Diamond League finals in Eugene on September 16 and 17.
Pole vault star Armand Duplantis again missed out on beating his own world record when he attempted 6.23m for the fourth time this summer.
The 23-year-old reigning Olympic and double world champion still won the event on Friday with a clearance of 6.10m, a meet record.
Once again, he was the only athlete to go higher than six metres. Sam Kendricks of the United States and EJ Obiena of the Philippines were second and third with 5.92m.
JakobIngebrigtsen set the first outdoor world record of his career in the little-run 2,000m.
Ingebrigtsen, 22, ran 4min 43.13sec to smash a record set in 1999, before he was born, by Moroccan great Hicham El Guerrouj, by more than a second and a half.
The 2,000m is not on the Olympic or World Championships programme, but the Norwegian said: "It's always fun to break a record."
Ingebrigtsen is the reigning Olympic champion in the 1500m and has held the world indoor record at the distance since February 2022 when he ran 3:30.60.
El Guerrouj holds that outdoor record too with a time of 3:26.00 set in July 1998.
Ingebrigtsen ran the fourth fastest ever outdoor 1500m time when he timed 3:27.14 in July but he lost his world title to Britain's Josh Kerr in Budapest in August.
Jamaican double Olympic champion Elaine Thompson-Herah claimed the 100m in a time of 10.84sec, her best time of the summer.
