Dominic Thiem would have preferred to still be in New York. As the fourth seed at the United States Open, Thiem was expecting to stick around at least until the second week of the last major of the year.

But, felled by a virus that forced him to withdraw from a warm-up tournament in Cincinnati, Thiem, whose nickname is Domi, lost in the first round at the Open to the 87th-ranked Thomas Fabbiano of Italy. Two days later, he was back home in Vienna, seeing doctors and resting.

Thiem, 26, returns to play for the European team in the Laver Cup in Geneva alongside Roger Federer, Rafael Nadal, Alexander Zverev, Stefanos Tsitsipas and Fabio Fognini. Team World features John Isner, Milos Raonic, Taylor Fritz (in for the injured Kevin Anderson), Nick Kyrgios, Denis Shapovalov and Jack Sock.

In March, Thiem defeated Raonic and Federer to win his first ATP Masters 1000 crown in Indian Wells, Calif., then upset Nadal and Daniil Medvedev to win the Barcelona Open. In May, he knocked out the No. 1, Novak Djokovic, to reach his second consecutive French Open final before losing, again, to Nadal.
