NEW YORK – He’d been suffering from a virus for 48 hours, had a stye in his eye and generally looked so gray and ashen you figured he might not even go the distance.
But Juan Martin del Potro is a tennis player. And unless they risk further injury by carrying on, tennis players usually play on.
Because you never know what can happen.
The 2009 champion somehow, improbably, and with some help from opponent Dominic Thiem, came back from two sets to none down to pull off a 1-6, 2-6, 7-6 (1), 6-1, 6-4 victory Monday to reach the US Open quarterfinals.
He saved two match points along the way, with two monster serves.
Del Potro will face five-time champion Roger Federer on Wednesday.
Federer already knows what to expect.
DelPo feeling Po’ly
Del Potro said he was seriously considering retiring in the middle of the second set, not even an hour in. He said the crowd support – the Grandstand was full to bursting and with buzz to burn – inspired him to hang in there.
“It was very important because I was trying to retire the match in the second set. Then I saw the crowd waiting for more tennis, waiting for my good forehands, good serves. I took all that energy to change in a good way and think about fight and not retire,” he said afterwards. “And I did well, and I start to enjoy little bit more about the fans. I think I did everything well after the third set. The crowd enjoy with me all points. It was unbelievable atmosphere.”
Smaller court only enhanced fan frenzy
At first, the Grandstand – only the third-biggest court on the grounds – seemed somewhat disrespectful to the only former champion in the lineup other than Nadal and Roger Federer.
It was the only one of the eight men’s and women’s singles matches being played Monday that wasn’t either on Arthur Ashe Stadium (five) or Louis Armstrong Stadium (two).

But it turned out to be a perfect arena for a dramatic comeback.
“I couldn’t breathe, I couldn’t move well. Dominic was dominating the match so easy. But then when we start the third set, I broke his serve very quick, and then I won the set in 20 minutes. Then the history change a lot,” del Potro said. “I starting to see the crowd. I took all the energy from the fans. That’s what I did in the end, just keep fighting. I don’t give up any points from the third until the fifth set. I was ready to win the match in that moment.”
Any comeback takes some cooperation. And Thiem did his bit. As mature and masterful as he can look when he’s winning, that’s how young he can sometimes still look when faced with a surging opponent or a tight situation.
The match ended on a double fault, which probably sums up Thiem’s day.
Next up, the 2009 rematch
Del Potro’s issues weren’t injury-related, which is welcome news for the next step. He’ll have more two days to recover from whatever virus he was wrestling with. So you’d have to expect he’ll be feeling a whole lot better when he takes the court against Federer in a rematch of that 2009 US Open final.
As Federer was dispatching Philipp Kohlschreiber in straight sets nearby, inside cavernous Arthur Ashe Stadium, he could hear the roars from the nearby Grandstand. “That’s the first time I experienced that. Clearly Grandstand wasn’t where it used to be. But, I mean, they had epic crowds,” Federer said.

“He’s a good guy. I know him well. But when he was hurt, clearly I didn’t see him for a long time. I was sorry for him because I think he had a legitimate good chance to become world No. 1 at that time. Him and (Nikolay) Davydenko, actually both of them got hurt at the wrong times in their careers. Both had a chance to go for world No. 1 at that time. ’09, I think it was,” Federer added. “So I’m really happy for him. It’s a good match to look forward to. Reminds me clearly of the 2009 finals that we had, which was an epic, too. I hope we can produce another good one.”
Federer was a combined 39-0 against his last three opponents at this US Open, and he kept those perfect head-to-heads intact.
Against del Potro, he’s an impressive 16-5. But when del Potro has defeated him, he has really hit him where it hurts.
Twice, the Argentine beat Federer at his hometown tournament in Basel, Switzerland (2012 and 2013). He defeated him at the ATP Tour Finals twice as well. And in that 2009 US Open final when Federer was going for a sixth consecutive title. Notably, Federer hasn’t won here since.
“The greatest guy on the history”
“I admire him, too. Everybody loves him. Is going to be interesting match for play. It will be after eight years again in the central court of this tournament. I know how to play if I want to win, but I will see how physically I feel after this battle,” del Potro said. “But always is a pleasure to play the greatest guy on the history.”
Federer’s crowd advantage is significant against nearly every opponent he plays – even against Andy Murray at Wimbledon, the crowd is somewhat torn. But in del Potro, he will run up against an opponent who will have plenty of support of his own.
He won the event, which always helps. But there’s a huge Spanish-speaking and Argentine population in New York. You could see and hear some of them going out of their DelPo-lovin’ minds during the match against Thiem.
But they’re not alone. There’s something about the gentle giant that just engenders a lot of love and devotion. Perhaps it’s the stark contrast between his hulking physicality and his gentle demeanour. Maybe it’s his journey.
“I don’t know. I think the people loves my effort to come back and play tennis. They know what have been through with all my wrist problems. They like one guy who never give ups, and he’s trying to play tennis,” del Potro said. “You can see my backhand is not good enough yet, but I’m still trying. I think the people likes that.”
