Her women's under-53 kilograms bantamweight victory at the World Championships in Guadalajara, Mexico in November 2022 was earned in dramatic fashion. 

Zuo Ju of China was seconds away from claiming gold at the Centro Acuático CODE Metropolitano, only for Greenwood to take the verdict in a sensational finish to the deciding round.

After recovering from losing the first round to send the match into a decider, Zuo soon established a 3-0 lead.

Greenwood then landed a punch with seven seconds left, only for Zuo to cancel that out with a kick to the body to move 5-2 in front.

With time running out, Greenwood pulled off a stunning back kick to the body.

Zuo was also penalised for stepping out of the mat, giving Greenwood a 6-5 lead before her body shot was upgraded to a four-pointer following a successful video review.

The decision by the judges sparked jubilant scenes in the American camp.

It capped an incredible day for Greenwood, who had ended home hopes of another gold with victory over Fabiola Guadalupe Villegas Machorro in the quarter-finals.

She then upset double Olympic medallist Tijana Bogdanović of Serbia in the last four.

Bogdanović collected a bronze medal, along with Ivana Duvančić of Croatia, while Zuo had to settle for silver.

Greenwood, who established herself in the sport by winning the US Open cadet title in 2016, did not move up to the senior ranks until 2021.

She made an immediate impact as she won the under-53kg Pan-American title in Cancun, Mexico, earning a 20-13 win over Brazil’s Leonor Dias de Lima in the final.

In 2022 she retained her title at Punta Cana in the Dominican Republic, winning her final against Cuba’s Tamara Robles Reve.

That proved to be ideal preparation for her startlingly effective World Championship campaign in Guadalajara, which established her as one of the sport's leading young talents.
