Dominic Thiem's tennis career came to an end as he lost to Luciano Darderi in the first round of the Vienna Open.

Former world number three Thiem, who won the Vienna title in 2019, was beaten 7-6 (8-6) 6-2 by Italian Darderi.

Austria's former US Open champion announced last week that he would retire after his home tournament.

Following his defeat to world number 42 Darderi, the crowd held up cards displaying the Austrian flag and the message 'Danke Dominic' ('Thank you Dominic').

Thiem, 31, gave an on-court speech before placing his racquet in a glass case, to be auctioned to raise funds for charity.

A ceremony was also held in Vienna on Sunday, including Thiem playing an exhibition set against Alexander Zverev, the player he beat to win the 2020 US Open.

Thiem won 17 titles at ATP Tour level during his career. He was a French Open finalist in 2018 and 2019 and runner-up at the Australian Open in 2020.

He also claimed important wins over all of the 'Big Three' - Roger Federer, Rafael Nadal and Novak Djokovic.

However, less than a year after his New York triumph, Thiem suffered a wrist injury that kept him off the tour for 10 months and resulted in his ranking plummeting to outside the top 350.

Thiem returned to the top 100 last year but has been unable to find his best game and confirmed in May that this season would be his last.
