Thiem maintains order on top half.
WHAT HAPPENED: Sixth seed Dominic Thiem must have received the memo before his third-round match against Frenchman Adrian Mannarino: Disorder is reserved for the bottom half of the US Open men's draw; the upper half, for now at least, should maintain orderliness.
The 23-year-old Austrian did his part to preserve calm on Saturday in Louis Armstrong Stadium, beating Mannarino, 7-5, 6-3, 6-4, to reach the fourth round and match his best showing at the US Open. The Austrian also made the Round of 16 in New York in 2014 (l. to Berdych) and 2016 (ret. to del Potro).
"I am pretty satisfied. I mean, it was way better than the first two rounds," Thiem said. "It was a tough match. For sure, by far, the best performance by me."
Hard courts have never been Thiem's surface of choice. The big-hitting right-hander prefers the slower red clay of Europe, which allows him more time to wind up and tee off with his topspin-heavy one-handed backhand and forehand.
His best results have come on red dirt as well, including two Roland Garros semifinals and six of his eight tour-level titles. But Thiem does have a hard-court crown in his trophy case (2016 Acapulco), and he's steadily making strides on quicker courts. In July, he reached the fourth round on the Wimbledon grass for the first time.
Mannarino had also been checking career-first boxes during what has become close to his best season on tour. The 30-year-old left-hander made the fourth round at SW19, and last month, he reached his first Masters 1000 quarterfinal in Montreal before falling to 18-year-old wunderkind Denis Shapovalov of Canada.
Mannarino presents a different type of game. His quick backswing and flat ball can trip up opponents who are accustomed to heavy topspin.
"I don't really like to play against him. He can hurt me or it's not really easy for me to get to my good shots against him, because he's playing flat. So it's tough for me to get my topspin and everything," Thiem said.
But Thiem had navigated their five previous meetings with ease, dropping only two of their 12 sets, and, after some early trouble, he did the same during their first Grand Slam meeting.
Mannarino broke to start and served for the set at 5-4, but on break point, he tapped a forehand volley wide. Thiem would cruise from there, winning the next five games and breaking early in the third to improve to 6-0 against the Frenchman.
"I didn't get the best start... So it was a tight first set and could easily go in his direction," Thiem said. "But I threw everything into the last, into the game at 4-5, and luckily it worked out, and I think this was also the turning point in the whole match, because I broke him a little bit, also mentally, I guess, with this first set. It would be, I think, very complicated if he would have won it."
WHAT IT MEANS: Thiem continues to win the matches he’s supposed to win and in good time. The Austrian needed only two hours and 14 minutes on Saturday.
"Of course there is always room to improve, but it was really way better, and I really like the feeling that it's getting better from match to match. It's necessary to improve a lot for the next round," Thiem said.
He will next face 2009 US Open champion and 24th seed Juan Martin del Potro of Argentina, who beat 11th seed Roberto Bautista Agut of Spain, 6-3, 6-3, 6-4.
More importantly, however, Thiem avoids the carnage that has rocked the bottom half of the draw, which has see Borna Coric beat No. 4 seed Alexander Zverev; qualifier Shapovalov oust No. 8 seed Jo-Wilfried Tsonga; and 29th seed Diego Schwartzman upset fifth seed and 2014 champion Marin Cilic.
MATCH POINT: Thiem clearly has what it takes to make a deep run at a Grand Slam. Is this the year he pushes ahead in Flushing Meadows?
