Dominic Thiem advances in Argentina but Frances Tiafoe stunned in New York

Dominic Thiem celebrates

Dominic Thiem was in efficient mood as he moved into the quarter-finals of the Argentina Open on Thursday with a routine win over Maximilian Marterer.

The Austrian was not really tested by Marterer, who was powerless to prevent Thiem’s 6-4, 6-4 success.

The result leaves Thiem with a 10-0 record at the ATP250 event, which he was won twice before.

Thiem will face Pablo Cuevas on the last eight after the Uruguayan overcame Joao Sousa 6-4, 7-5.

David Ferrer, though, has been knocked out after he was edge by Albert Ramos-Vinolas 3-6, 7-6 (11-9), 6-3.

The result will surely be extra tough for the 36-year-old to stomach after he squandered two match points.

Meanwhile, at the New York Open, Frances Tiafoe was a surprise casualty after he suffered a 6-3, 7-5 upset at the hands of Jason Jung.

He was not alone in making a shock exit, though, with Australian John Millman also crashing out, in his case at the hands of Guillermo Garcia-Lopez 7-6 (7-4), 1-6, 6-4.

Sam Querrey, the sixth seed, is safely through though after a 6-3, 6-4 win against Radu Albot.
