Brady advanced to the fourth round in a major championship for the first time, but she appeared overwhelmed by the big stage, converting only 38 percent of her first serves in the first set. You could see and hear some of them going out of their DelPo-lovin' minds during the match against Thiem.
Del Potro, though, is good at comebacks.
Del Potro was struggling, and he had to fight with the temperature but after the medical time out he simply flourished and came back from the dead. Of course, the third set was bad.
Del Potro took the game then rolled a disintegrating Thiem to force a decider.
"I didn't get the best start". Is true that I was able to have the break earlier, but really I felt more comfortable from the beginning. I know Dolgopolov is a player who can play unbelievable shots but sometimes he can be a little bit unpredictable. Thiem told reporters. "I threw everything into the game at 4-5, and luckily it worked out, and I think this was also the turning-point in the whole match because I broke him a little bit, also mentally'".
"Obviously, that was good enough to beat me that day".
In normal circumstances, Del Potro would stand as a significant roadblock, but you have to wonder what shape he will start in after taking five sets and just over three-and-a-half hours to overcome Dominic Thiem.
Thiem had two match points at 6-5 but Del Potro saved them with consecutive aces - one of them at 204 kph.
Nadal crushed Alexandr Dolgopolov 6-2 6-4 6-1 in one hour and 41 minutes before Federer swept past Philipp Kohlschreiber 6-4 6-2 7-5 in an equally clinical fourth-round display to surge into a mind-boggling 51st grand slam quarter-final.
We have Roger on one side of the court, having some problems with his back, exhausted a little bit. In London 2012, he took Federer to a 17-19 third set in the longest three-setter ever played. The Argentine mounted a stunning comeback against Thiem to set up a date with Federer. When it was over, del Potro raised both arms overhead and threw his head back, enjoying the fans' adulation.
He collected himself for an on-court interview with Pam Shriver of ESPN, who had to wait a moment for the "Olé, olé, olé!"
Still, buoyed by a boisterous Grandstand crowd chanting "Ole!" and his nickname, "delPo", he never gave in or gave up. What can I say. "I was sick the last two days and I just tried to improve game after game", 24th seed Del Potro, who took a pill near the end of the opening set, said on court. "And then when I saw all this crowd cheering for me, my energies went up".
Del Potro will face five-time champion Roger Federer on Wednesday. Del Potro's serve, despite not being big has been consistent and his court movement has looked fantastic - something he will need to do well against Thiem, who is one of the more powerful players on tour. Del Potro's winners wreaked noise and singing that sounded like just a sliver - just a sliver - of Boca Juniors vs. River Plate in Buenos Aires.
