Impressed with his performance against the South Africa 7s Academy, which had stars like Cecil Afrika and Werner Kok, coach Baber recruited him into the 7s extended team for the 2019–2020 7s series.

Due to the COVID-19 pandemic, the delay of the 2020 Tokyo Olympics forced Baber to lose two of his top players, Vilimone Botitu and Aminiasi Tuimaba, who both took contracts in France.
