U.S. sprinter Sha'Carri Richardson failed to impress in her highly-anticipated return to the track, finishing last in the women's 100 meters at the Prefontaine Classic in Eugene, Oregon. This was Richardson's first race since June's U.S. Olympic Trials, as she was suspended from the 2020 Tokyo Games for a positive marijuana test.

Her highlight though, came in a post-race interview with NBC Sports, calling her return "great" -- and staking her claim as one of the world's top track-and-field athletes despite the disappointing finish.

"I'm not upset with myself at all," Richardson said. "This is one race. I'm not done. You know what I'm capable of. Count me out if you want to. Talk all the s--t you want because I'm here to stay. I'm not done. I'm the sixth-fastest woman in this game, ever, and can't nobody ever take that away from me. Congratulations to the winners. Congratulations to the people that won, but they're not done seeing me yet -- period." 

The Prefontaine Classic pitted Richardson against the three women's 100-meter medalists from Tokyo -- Jamaica's Elaine Thompson-Herah, Shelly-Ann Fraser-Pryce and Shericka Jackson -- along with fellow Americans Teahna Daniels and Javianne Oliver. Like in Tokyo, Thompson-Herah took gold, Fraser-Pryce won silver and Jackson took bronze. Daniels finished fourth while Oliver placed sixth. 

Richardson finished ninth with a 11.14, well below her personal-best of 10.72 -- the sixth-fastest time in the event's history -- and 10.86 from the Olympic Trials. 

Hours before those Olympic Trials, Richardson used marijuana to cope with the death of her mother. While USA Track and Field described the situation as "incredibly unfortunate" and "devastating," it did not reverse Richardson's one-month suspension that would've allowed her to compete in the Tokyo Olympics. 

"That sent me in a state of mind, in a state of emotional panic, if anything," Richardson said of her mother's passing. "During all that, I still, even though I'm here, I still have to go out and put on a performance for my dream."

While the 21-year-old Richardson struggled in the Prefontaine Classic, Thompson-Herah bolstered her growing legend. Thompson-Herah, who earned three gold medals (100-meter, 200-meter and 4x100-meter relay) in Tokyo,  posted the second-fastest women's 100 meters time in history with a 10.54. Florence Griffith Joyner's world record of 10.49 has stood since 1988.

To Thompson-Herah, her best is still yet to come. 

"I ran 10.5 [today] and I think I have so much more in me," Herah told NBC Sports.
