Attempting to meet the qualifying mark of 18.80, Warren opened with an 18.21m, matching her season's best, then followed up with an 18.23m-effort in the second round before sealing her spot among the six qualifiers from Group A as one of the best performers.

Speaking earlier this month to Nashville news, Gittens said, "It's been so surreal, but at the same time, I've been training for this moment since I stepped foot with coach Jan Pippin."

Gittens, who was training for the Olympics in College Station, Texas added, "It's exciting to have goals and dreams achieved, but also always knew this day would happen, so those two feelings are clashing together, feel like I'm stuck and I don't know how I feel."

Gittens, was born in T&T before moving to Nashville as a toddler and is the heptathlon national champion.
