Perth Wildcats star Alex Sarr has catapulted up the NBA draft boards after a stunning two games against G-League Ignite in Las Vegas.

Sarr arrived in Australia rated as a first round draft pick and then some analysts upgraded him to a top -10 selection.

But two outstanding games against G-League Ignite have shown he is among the best young players in the world.

On a night where Bryce Cotton scored 40 points including eight three-pointers from 10 attempts, the Wildcats won 127-112. But it was Sarr who had tongues wagging with 26 points, 10 rebounds and six blocks. That followed 17 points, seven rebounds and six blocks in the first game on Thursday.
