Brazil's Vinicius Rodrigues and Petrucio Ferreira both won 100 metre sprint events on the opening day of the World Para Athletics Grand Prix in São Paulo.
The home crowd at the Paralympic Training Centre was delighted to see Rodrigues break a world record in the men's 100m T63, setting a time of 11.95 seconds.
He surpassed his own record of 11.99 from last year, remaining the only athlete in his class to smash the 12-second mark.
"I worked through a groin injury in the past couple of weeks, but still managed to run this fast," Rodrigues said.
"It shows how good my work with our team has been and how much further we can go."
His performance earned him a place at the Lima 2019 Parapan Am Games in August and the Dubai 2019 World Para Athletics Championships in November.
