Shericka Jackson's pursuit of Flo-Jo's 200m world record is Diamond League Final's main attraction

The men's 200 metres at this weekend's Prefontaine Classic will feature teenage phenom Erriyon Knighton and world silver medallist Kenny Bednarek, along with Canadian star Andre De Grasse. In most other track meets you'd stage it last, and let the whole program build up to that last showcase of speed and depth.

But this weekend, at the meet that will double as the Diamond League Final, the men will run second-last. In boxing you would call them the "chief support."

No, the men's 200 isn't miscast as the Pre Classic's co-main event. And no, as talented as that field will be — even without Noah Lyles, who will stick to the 100 this weekend — the men don't figure to steal the show from the headliners.

Make that headliner, singular.

Not that Shericka Jackson, the two-time champion in the women's 200 metres, and the world's top performer over that distance this season, is running by herself. Jackson will line up against big names like Daryll Neita and Marie Josée Ta Lou.

But Jackson, 29, isn't chasing other runners; she's pursuing Florence Griffith-Joyner's world record. The time — 21.34 seconds — has towered over women's 200-metre sprinting since 1988. It's older than any of the women running Sunday's 200, and Jackson, a five-time world and Olympic champion, has a chance to take it down.

So Sunday's main event doesn't pit any two runners against each other on the track.

The featured race is Jackson versus "Flo-Jo" versus history.

Jackson has three sub 21.5-second clockings on her resumé — the most recent came last week at Diamond League Brussels, when she ran 21.48. A rare example of a sprinter knocking on the door of a women's sprint world record.
