Tomas Berdych finally broke the dogged resistance of Kevin Anderson to reach the fourth round of the Australian Open in Melbourne.
It took 150 minutes and 29 games before Berdych finally broke the South African's serve - with the world No.7 failing in eight previous attempts.
However once Berdych got the breakthrough, the end came quickly as he chalked up a 7-6 (7-5) 7-6 (7-1) 6-1 victory in two hours and 47 minutes.
"It was not easy at all, and especially the first two sets [were] really about just a small chance that I was waiting for," Berdych said.
"I got some chances to make a break during the first two sets, but ... he played well, served well and just saved [his serve] every time."
But the experienced Berdych knew that the lone break didn't equate to an automatic win.
"You still have to stay really focused, because it could be really the tricky moment," he said.
Del Potro through
Meanwhile, former US Open champion Juan Martin del Potro continued his comeback from serious injury as he beat Taiwan's Lu Yen-hsun to reach the fourth round.
The Argentinian world number 11 beat Lu 6-2 6-3 6-0 to equal his best grand slam performance since lifting the US title in 2009.
"I played I think the best match of the year. Only four matches in this year, but I was really confident with my forehand in every part of the match," del Potro said.
"I served much better than the last two matches, and my game is still improving. So it's a good sign for the next round."
Del Potro missed much of 2010 as he underwent wrist surgery but he stormed up the rankings when he returned to full action last season.
The big right-hander has set his sights on breaking back into the game's elite and now needs to beat Germany's Philipp Kohlschreiber to equal his best result in Melbourne, the quarter-finals in 2009.
