MIAMI — Two-time Miami Open champion Andy Murray fought back for a 4-6, 6-3, 6-4 win over struggling Italian Matteo Berrettini in the first round at Hard Rock Stadium on Wednesday.

Berrettini needed medical attention near the end of the second set after appearing to almost faint on court but he battled on.

The Italian recently returned to the tour after an injury-plagued 2023, reaching the final of a Challenger event in Phoenix.

He broke Murray's serve in the first game of the match and was in firm control of the opening set.

But he faded badly in the second and called a medical timeout when 5-2 down after walking off the court looking dizzy.

The weather in Miami was not particularly hot or humid and more pleasantly mild than has often been the case at the tournament in past years.

The 27-year-old former world No 6, put up a better fight in the third set, but a solid-looking Murray saw the match out in two hours and 47 minutes.

Murray made just 20 unforced errors while Berrettini committed 44, as the Scot clinched his fourth consecutive first-round win.

"There is life in the old dog yet," wrote Murray on the television camera lens at the end of the game and he was pleased with the manner of his win.

"I started off a little bit slow, but I do think I played pretty well from the middle of the first set until the end of the match," he said.

"I created a lot of opportunities and he was struggling for a little bit at the end of the second and beginning of the third. I capitalized on that and got off to a quick start in the third. I served it out well in the end."

Murray, who won the Miami Open in 2009 and 2013, will meet 29th-seeded Argentine Tomas Martin Etcheverry in the next round.

Two Chinese men's players had mixed fortunes in the first round on Wednesday.

Shang Juncheng, who reached the second round at Indian Wells last week, repeated the feat after beating Miomir Kecmanovic of Serbia, 7-6 (5), 4-6, 7-6 (5). But compatriot Zhang Zhizhen lost to American Martin Damm Jr in two tiebreakers, 7-6 (2), 7-6 (3).

Shang next plays the 27th-seeded Alejandro Davidovich Fokina of Spain.

Osaka encouraged

In the WTA event, four-time Grand Slam winner Naomi Osaka had little trouble in defeating Italy's Elisabetta Cocciaretto 6-3, 6-4 in one hour, 18 minutes to move into the second round.

Osaka is ranked 229th in the world after taking a maternity break and spending over a year out of the game. The 26-year-old is returning to the scene of her run to the 2022 final, where she lost to Iga Swiatek.

Osaka said her performance was the best since she returned to the tour at Brisbane in January.

"Honestly, this is probably the most free that I was able to hit my balls, the closest to the feeling that I want to capture going forward, so I would say that this is probably my best match in terms of shot-making.... I was swinging the best that I have since I have been back," said the Japanese star.

Osaka will face another mother in the second round when she takes on Ukraine's Elina Svitolina, who in 12 months back on the circuit is already back inside the top 20 — a return which Osaka says has inspired her.

"I remember watching her play at Wimbledon while I was pregnant and thinking that I want to be there too one day. I think she's always just been a really great player so it's not surprising to me she's back in the top 20. It's where she belongs," said Osaka.

American Sloane Stephens beat Angelique Kerber 6-2, 6-3 in a meeting of two former Grand Slam champions.

Stephens, celebrating her 31st birthday, was on top throughout against the German who had shown good form in Indian Wells where she reached the fourth round.

Stephens, the 2018 Miami champion, will play Romania's 19th-seeded Sorana Cirstea in the second round.

Zhu Lin, the only Chinese woman in action on Wednesday, stopped her five-match losing run by beating Marie Bouzkova of the Czech Republic, 6-2, 6-4. Zhu faces No 5 seed Jessica Pegula of the US in the second round.

The WTA tournament's second-round action will also see China's No 7 seed Zheng Qinwen go up against Katerina Siniakova of the Czech Republic, Yuan Yue against No 8 seed Maria Sakkari of Greece, Wang Xinyu against No 16 seed Veronika Kudermetova of Russia and Wang Xiyu against No 22 seed Anna Kalinskaya of Russia.
