Nadal tried that strategy just long enough to drop the opening set. Once he scrapped it on the fly, everything changed, and it didn’t take long for him to power into the final.
Closing in on a third title at Flushing Meadows and 16th Grand Slam championship overall, Nadal overcame a so-so start with an overwhelming performance the rest of the way Friday night, taking nine games in a row during one stretch to beat 2009 champion del Potro 4-6, 6-0, 6-3, 6-2.
“I was wrong in the way that I was trying to play, no? … I started to understand a little bit better what I needed to do to try to be a little bit more unpredictable, because he was waiting for me in his backhand side,” Nadal said. “He only had to cover 60 percent of the court most of the time.”
Once the Spanish lefty started hitting more forehands down the line to the righty del Potro’s backhand, Nadal explained, “I was more unpredictable, and he was more in trouble, because he didn’t know where to go.”
His opponent’s take?
“He played so smart from the second set until the end of the match,” del Potro said. “He was dominant.”
No. 1 Nadal will be a significant favorite Sunday against No. 32 Kevin Anderson of South Africa who beat Pablo Carreno Busta 4-6, 7-5, 6-3, 6-4 to become the lowest-ranked U.S. Open finalist since the ATP’s computer rankings began in 1973. The 6-foot-8 (2.03-meter) Anderson, who won an NCAA doubles title at the University of Illinois, is equipped with a big serve, certainly, but he only once had even been a quarterfinalist at a major until this week. He’s also lost all four previous matches against Nadal.
Plus there’s this: Nadal looked as good as ever over the last three sets against del Potro, further confirmation of his return to the height of his powers. Nadal is again healthy and capable of excellence, after wrist and knee injuries dulled his effectiveness in 2015 and 2016 — the first seasons since 2004 in which he not only failed to win a Grand Slam trophy but didn’t even make a final.
“It’s been an amazing season, of course,” Nadal said, “after a couple of years with some troubles, injuries, tough moments.”
He reached the Australian Open final in January, losing to Roger Federer, then claimed his record 10th French Open championship in June.
When Nadal’s uncle and coach, Toni, was asked to describe his nephew’s year, this was the reply: “It’s easy to describe it. He has played really good.”
Save for that first set Friday, in which Nadal had nine winners and 10 unforced errors, he barely missed his targets. The numbers the rest of the way: 36 winners, 10 unforced errors.
The key was that Nadal decided he needed to force del Potro to worry about his backhand, a two-handed shot he had to rebuild after three operations on his left wrist. That stroke was effective early, but only for so long.
“He was playing all the time to my backhand, and when you don’t have that confidence to play three, four hours with a good backhand against Rafa, it’s just a matter of time,” del Potro said.
Dealing with the flu and a fever, del Potro came back from a two-set deficit to win his fourth-rounder in five sets, then got past 19-time major champion Federer in the quarterfinals in four. Maybe it was all too much for del Potro, whose one Grand Slam title came via wins over Nadal in the semifinals and Federer in the final in New York eight years ago.
That was the last time Nadal lost i a major semifinal; he’s now won 15 in a row. This time, the 24th-seeded del Potro actually edged ahead with the match’s first break, going up 3-2 in the first set when a backhand return caught the net tape and took a fortuitous roll over to Nadal’s side for a winner.
“Lucky,” del Potro acknowledged later.
That moment was greeted with a chorus of “Ole, ole, ole, ole! Del-po! Del-po!” for the popular Argentine, who would serve out that set, punctuating it with a forehand.
That’s when Nadal knew he needed to change things up. He wouldn’t relinquish another game until he owned the second set and a 3-0 lead in the third.
In del Potro’s first service game of the second set, Nadal finally earned a break point with some fantastic defense, throwing himself to his left to somehow get back one massive forehand from del Potro, who — perhaps stunned that ball came back — sent his next forehand long.
By now, Nadal was using his own intimidating, topspin-lathered forehand to press the matter whenever del Potro left a ball short.
As Uncle Toni put it, Nadal “began to attack, with very good decisions.”
Hours earlier, Anderson was so excited by his semifinal victory that he celebrated as if it made him the champion, stepping on a chair and then a flower box to help him climb into his guest box in the stands.
“I don’t know if it’s appropriate,” Anderson said. “It certainly felt the right thing to do.”
Hip, leg and elbow injuries caused him to miss time this season. Ankle surgery, plus left knee, right shoulder and groin injuries were problems last year.
He is appearing in his 34th major tournament and took advantage of a draw depleted by withdrawals of several top players, including past champions Novak Djokovic, Andy Murray and Stan Wawrinka.
“It’s nice,” Anderson said, “that some of them gave us a bit of a shot to make a run in this tournament.”
