Bernard Tomic has won through to the third round of the Citi Open in Washington, beating Donald Young of the United States in straight sets.
But the news wasn’t so good for fellow Australians James Duckworth and John Millman, who were each beaten in the second round.
Tomic, the No.3 seed, was forced to fight through a first set tiebreak, after dropping serve when up 5-4 in the opening set, before running out a 7-6 (7-4) 6-3 winner.
He sent down 12 aces in the win, and rolled through the second set where he twice broke Young’s serve.
Tomic will face Ivo Karlovic – who he holds a 2-1 win/loss record over – in the third round after the towering Croatian recorded a 6-3 7-6 (7-4) win over American Brian Baker.
Meanwhile Duckworth struggled to handle big-serving American John Isner, winning just nine points on return in the 6-3 6-4 loss.
No.1 seed Isner banged down 14 aces in the win, and dropped just three points on his first serve as he closed out the straight sets victory.
He’ll now face Cypriot Marcos Baghdatis in the third round, after Baghdatis breezed past Millman in straight sets 6-2 6-4.
Isner joins fellow seeded players Steve Johnson, Borna Coric, Gael Monfils, Alexander Zverev, Benoit Paire and Gilles Muller in the third round after they all enjoyed straight sets wins on the day.
Not so lucky was South African ninth seed Kevin Anderson, who fell 5-7 6-4 7-6 (7-3) to Tunisian Malek Jaziri in a two-and-a-half hour battle.
Also exiting the tournament was Serbian Viktor Troicki, who was humbled by American qualifier Ryan Harrison 7-6 (7-4) 6-4.
For world No.158 Harrison – who is still only 24 and was once considered a future star of American tennis – the win was sweet relief, especially as he only converted three of 22 break points.
“When you’re in a situation like I’m in – that you haven’t won a ton of matches – it seems like it’s tough to convert on opportunities. And it’s easy to get discouraged. You miss your first couple, and you feel like you’ve lost the match,” he said.
