Jordan Thompson is the last remaining Australian in the men’s draw of the Brisbane International after wildcard Sam Groth lost his second-round match in straight sets.
Groth was clinically disposed of by world No.8 Dominic Thiem, who claimed a 7-6 (7-5) 6-3 victory at the Queensland Tennis Centre.
Both players held serve throughout a tense opening set but an overblown forehand from Groth handed Thiem the tiebreaker, and the ascendancy along with it.
The Austrian fourth seed then seized the moment when his break point chance arrived in the second set and he wrapped up the match with no trouble.
Thiem, who had a first-round bye, will take on Grigor Dimitrov in the quarter-finals after the Bulgarian defeated Nicolas Mahut 6-2-6-4 earlier on Thursday.
For Groth, who is only playing in Brisbane because of a hip injury to John Millman, there were still some encouraging signs for the summer ahead as he looks to climb back up the ATP rankings following a disappointing 2016 campaign.
His booming serve was on song early, but Thiem matched him in that department, and he also failed to convert any of his four break opportunities.
World No.180 Groth has a wildcard spot at the Australian Open later this month.
