Alexander Zverev notched his 18th Masters semifinal victory in Rome on Wednesday, but not without a scare that evoked memories of his past injury woes.
The world No. 5 from Germany defeated Taylor Fritz 6-4, 6-3, setting up a thrilling last-four clash with Alejandro Tabilo, the Chilean journeyman who earlier stunned Novak Djokovic in the tournament.
Zverev's moment of concern unfolded in just the third game on center court at the Foro Italico when he took a tumble on the clay, landing awkwardly on his front. The 2017 champion sustained cuts to his left wrist and a finger in the fall, requiring treatment from the tournament physio before resuming the match.
Zverev, 27, suffered a serious ankle injury at the 2022 French Open after falling on the clay of Roland Garros during his semifinal against Rafael Nadal and missed the rest of the season.
On Wednesday, however, he was able to dust himself off to defeat Fritz in 90 minutes, firing 20 winners with six aces and not facing a single break point.
"Taylor has been one of the best players on clay this year. To have a win like that is great for me, especially after the fall," Zverev said.
"I still have a little bit of pain, so once the adrenaline settles I'm going to check out tomorrow what it is. But definitely happy with the win."
Zverev is the highest-ranked man left in the event after Daniil Medvedev's elimination on Tuesday.
As well as Djokovic's exit, Italian world No. 2 Jannik Sinner and third-ranked Carlos Alcaraz both dropped out injured before the tournament.
Holger Rune, who lost last year's final to Medvedev, Madrid champion Andrey Rublev – ranked sixth in the world – and beaten finalist Felix Auger-Aliassime have also been eliminated.
Chile's Tabilo will play his first-ever Masters 1000 semifinal at the age of 26, after seeing off unseeded Zhang Zhizhen of China 6-3, 6-4 in one hour and 26 minutes.
"I just can't believe it right now, still trying to soak this in... Definitely an unforgettable two weeks for me," said a delighted Tabilo, the 29th seed who knocked out top-ranked Djokovic on Sunday.
"It's definitely the best tennis of my life right now, trying to keep a poker face there because inside I'm just so nervous, every time trying to close out the match gets a little bit tighter."
Tabilo, in fact, had far less trouble on Wednesday than he did in his battle with Karen Khachanov in the previous round, not facing a single break point on his way to the biggest match of his career at the last major tournament before the French Open.
Collins wins 19th of 20 matches
Women's second seed Aryna Sabalenka needed just an hour and 13 minutes to see off Jelena Ostapenko 6-2, 6-4 on her way to the semis, improving her record against her Latvian opponent to three wins and no defeats.
Sabalenka will next take on Miami Open winner Danielle Collins who eased past Victoria Azarenka 6-4, 6-3.
"With this amazing atmosphere and with this amazing support ... that's why I'm super motivated here and that's why I always say that this is the dream tournament for me to win," said Sabalenka.
The 26-year-old could get a rematch of the Madrid final, which she lost in dramatic fashion to world No. 1 Iga Swiatek earlier this month.
Sabalenka, who has won the two most recent Australian Opens, was in a different class to Ostapenko, a former French Open winner, who could do nothing in the face of some punishing hitting.
Rome is the first time since the 2013 French Open that the top three women have reached the last four of a WTA event of 250 level or higher, with Swiatek and world No. 3 Coco Gauff in the other semifinal on Thursday.
The 30-year-old Collins, ranked 15th in the world, announced in January that this would be her final season on the tour before retiring.
She now has 19 wins in her last 20 matches, dating back to the start of Miami where she captured her first WTA 1000 title.
Her only loss since came against Sabalenka in three sets in the fourth round of the Madrid Open.
