Rafael Nadal rampant at US Open
New York: Rafael Nadal launched his tilt at a fourth US Open title with a swift defeat of John Millman as other leading seeds in his half of the draw tumbled out in the first round.
Four players in the world's top 10 — Dominic Thiem, Stefanos Tsitsipas, Karen Khachanov and Roberto Bautista Agut — lost Tuesday to ease Nadal's potential path to the final.
The Spanish second seed — US Open champion in 2010, 2013 and 2017 — needed barely two hours on Tuesday to see Millman off 6-3 6-2 6-2 at Arthur Ashe Stadium with the world number 60 from Australia unable to reproduce the magic that saw him stun Roger Federer here a year ago.
"The beginning, the first match, is always a little bit new even if I've played here plenty of times," said Nadal, who meets Aussie Thanasi Kokkinakis next.
"I think I played well and in general am very happy with the way I started.
"He (Millman) showed last year what he's able to do when he's doing well and I came on court with a lot of respect."
Two-time French Open runner-up Thiem was upset by Italian giant-killer Thomas Fabbiano 6-4 3-6 6-3 6-2, as the Austrian slumped to another first-round exit, having
lost at the same stage at Wimbledon.
"I got very tired and exhausted after two sets. I'm far away from 100 percent," Thiem said.
"It was not the real me there on the court." Greek eighth seed Tsitsipas struggled with cramps and accused umpires of having "preferences" after he fell to a 6-4 6-7 (5/7) 7-6 (9/7) 7-5 defeat by Next Gen rival Andrey Rublev in a gruelling four-hour slog.
Tsitsipas, for whom it was also a second successive
Grand Slam opening-round defeat, was hit with a point penalty for a time violation in the final set.
Russian ninth seed Khachanov lost to Canada's Vasek Pospisil in five sets, with 10th seed Bautista Agut of Spain succumbing in similar fashion to Mikhail Kukushkin of Kazakhstan to leave that quarter of the draw, which features Nick Kyrgios, wide open.
Alexander Zverev, seeded sixth, battled into the second round by defeating Moldova's Radu Albot 6-1 6-3 3-6 4-6 6-2, while Marin Cilic, the 2014 champion, advanced in straight sets over Slovakia's Martin Klizan.
Igning women's US Open champion Naomi Osaka confronted severe nerves to come through in three tough sets against Russia's Anna Blinkova, the world number 84.
Osaka suffered a first-round exit last month at Wimbledon and the Japanese star struggled to put away Blinkova before prevailing 6-4 6-7 (5/7) 6-2.
