Rafael Nadal is back to feeling healthy. Probably not a coincidence that he's back in the Australian Open semifinals.
Playing his familiar brand of court-covering, ball-bashing, opponent-frustrating tennis, Nadal claimed 20 of his first 23 service points and saved the only two break chances he faced, ending American Frances Tiafoe's best Grand Slam run with a dominating 6-3, 6-4, 6-2 victory Tuesday night.
"I feel lucky to be where I am after all the things I went through," said Nadal, who quit during his quarterfinal at Melbourne Park a year ago because of a right leg problem, again during his semifinal at the U.S. Open in September because of a painful right knee, and then had offseason surgery on his right ankle.
Nadal, 32, reached his 30th major semifinal and prevented Tiafoe from getting to his first, two days after he turned 21.
The two hadn't played each other before, though they did practice together at Roland Garros back in 2014, when Tiafoe was a teen in the junior competition.
Entering this year's Australian Open, the 39th-ranked Tiafoe had never been past the third round at a major. But he knocked off two-time Slam runner-up Kevin Anderson and 20th-seeded Grigor Dimitrov on the way to the quarterfinals, drawing plenty of attention for his play — and his bare-chested, biceps-slapping celebrations inspired by LeBron James.
As usual, Tiafoe was animated and talkative Tuesday. He lamented missed shots with a self-admonishing "Oh, Frances!" He marked good ones with a shout of "Let's go!"
But it all came to a screeching halt against Nadal, a 17-time major champion.
Tiafoe, who is from Maryland, was broken the initial time he served in each set, which was all Nadal needed, given how well he handled his own service games. He's been reluctant to go into detail about a recent tweak he made to his serve, saying it's "nothing drastic, nothing dramatic."
He spoke after Tuesday's win about going for winners on his first forehand following a serve, something he called "very important ... at this stage of my career."
Whatever he's doing is working. And how. Nadal has won every set he's played in the tournament, the first time he's done that en route to the semifinals in Australia since 2009, the only time he won the championship.
Now Nadal goes up against another opponent much younger than he is, 20-year-old Stefanos Tsitsipas, who upset Roger Federer in the fourth round.
The 14th-seeded Tsitsipas became the first player from Greece to earn a semifinal berth at a major, beating No. 22 Roberto Bautista Agut 7-5, 4-6, 6-4, 7-6 (2) earlier Tuesday.
"It's going to be interesting," Tsitsipas said about his matchup against Nadal. "I feel all right with my game. I feel like I can do something good against him."
Asked about all of these kids trying to elbow their way to the top of tennis, Nadal smiled and said: "They can wait a little bit."
