Alexei Popyrin is refusing to let his mind wander after marching ominously ever closer to a blockbuster US Open showdown with defending champion Novak Djokovic.
Popyrin lived up to his star billing to lead four Australians into the second round on day one at Flushing Meadows.
The recently crowned Montreal Masters champion cruised past Soonwoo Kwon without even hitting top gear, eventually progressing with a 7-5 6-2 6-3 win in a tick over two hours.
