Defending champion Alex de Minaur powered into the Washington Open quarterfinals with a clinical 6-2, 6-3 victory over fellow Australian Cruz Hewitt.

Women’s top seed Jessica Pegula also advanced, rallying to beat Magdalena Frech 3-6, 6-3, 6-0 while men’s second seed Ben Shelton outlasted Ugo Humbert 6-7 (3/7), 6-3, 6-4.

Top-seeded De Minaur was always likely to prove too much for 17-year-old qualifier Hewitt – son of Aussie great Lleyton Hewitt – who had only captured his first ATP victory in Tuesday’s first round.

The first set threatened to become a demolition as De Minaur raced to a 5-0 lead.

But Hewitt found his feet, breaking back in the sixth game and holding serve before succumbing 6-2.

Cheered on by a crowd that included his famous father, Hewitt started the second set brightly.

But he was broken again on his second service game and could not reel in De Minaur, who warmly embraced the youngster at the net after taking the match.

It was the first head-to-head ATP Tour match between the two, who have known each other for years.

“It was definitely weird,” said De Minaur. “I knew I was going to play him on the tour someday, but I didn’t actually expect it to be this week.

“It was an amazing feeling. Even all the lead up, seeing all the incredible pictures that we have together and how we’ve both grown up.

“I’m glad I managed to get through, but I’m sure we’re going to have many battles in the years to come.”

De Minaur next faces American Brandon Nakashima, who upset Czech seventh seed Jakub Mensik 7-6 (7/5), 3-6, 6-4.

But the third set was a tense affair and after seizing a break for a 5-4 lead Shelton had to fend off a break point before polishing off the match with a sharply angled serve that Humbert smacked into the net.

“For me, it was all about heart tonight,” Shelton said after lining up a meeting with Chile’s Alejandro Tabile, a 6-3, 7-6 (8/6) winner over France’s Terence Atmane.

Pegula also had to rally from a set down, saying she started her match against Poland’s Frech “just a little off” after a first-round bye.

“I wasn’t quite attacking the ball, and I felt like once I did that, then everything else kind of started to click together,” said Pegula, who finished with 42 winners and won 12 of the last 15 games.

Pegula next plays fifth-seeded Anna Kalinskaya, who saved two match points to beat Indonesia’s Janice Tjen 1-6, 6-3, 7-6 (9/7).
