The Australian, who didn't face a break point, became the fourth man born in 2008 or later to win a tour-level match and youngest Washington match winner since Japan's Kei Nishikori in 2007. He'll play the winner of countryman and mentor Alex de Minaur and former world No.3 Stefanos Tsitsipas in the next round, with their later match washed out. He had warmed up with father Lleyton, the former world No.1, two-time major winner and 2004 Washington champion, who told him to lap up the moment. Hewitt said it would be a "dream" to square off against de Minaur, who he likened to a big brother. "Obviously if I play Alex, that would be a dream to share the court with him," the teen said.
