“Dumbo” might not sound like the most flattering nickname, but In Gee Chun has embraced it.

Years ago, her coach in South Korea gave her the moniker because of her exceptionally keen hearing, the ability to hear someone clearing their throat or opening a soda two holes away. She leaned into it ever since. The Disney character adorns her golf bag and is her driver headcover, and her fans refer to themselves as the “Flying Dumbos.”

At the U.S. Women’s Open on Friday, everyone heard Chun’s footsteps. She shot a three-under-par 68 to claim an early share of the lead at Riviera with Jennifer Kupcho and Japan’s Hinako Shibuno.

Many of the contenders were still on the course at press time, but Chun assured herself of a prime position heading into the weekend, in the hunt for her fourth major championship. She won the Open in 2015, Evian in 2016, and Women’s PGA in 2022.

Were Chun to win this tournament, she would be in rarefied air with bookend victories separated by 11 years. According to Elias Sports Bureau, among women with multiple U.S. Open titles, Meg Mallon had the longest gap (13 years apart), followed by Annika Sorenstam (10 years).

Of course, there’s a big difference between being at a logjam atop the leaderboard on Friday and lifting the Harton S. Semple Trophy on Sunday.

“Just stick to the game plan, nothing changes,” Chun said of her mindset heading into the weekend. “I don’t want to think about the future to put extra pressure on me.”

Speaking of extra pressure, Kupcho has an arrangement with her mom. They’ll talk before and after the tournament, but not during it.

“Me and my mom kind of have an understanding,” she said, “like, ‘Just don’t text me. I don’t want to hear from you if I play good. I don’t want to hear from you if I play bad. We’ll talk at the end of the tournament.’”

Kupcho, raised in Colorado, said she hasn’t banned her folks from attending, “But I don’t think they’re going to.”

Maybe she could have used some TLC on Friday. After leading outright Thursday with a 66, she came back to earth with a 73.

That was still enough to keep her squarely in the mix. The same could not be said for Michelle Wie West, who followed a 75 with a 74 — a deflating finish for the LPGA legend who came out of retirement to use her final year of exemption to play at Riviera.

“Obviously I would be lying to say I wasn’t disappointed. I would have loved to have made the cut today, granted all day,” Wie West said. “But I had a blast honestly, with playing here at Riv, such a special week to have played it, and to have family, friends, a lot of familiar faces coming out, it was a lot of fun.

“I hit some good shots, hit some good putts, and kind of felt that feeling again, which is awesome.”

Nelly Korda, ranked No. 1 in the world, was coming on strong Friday afternoon in the wake of a ho-hum 73 in the opening round. She had three birdies and six pars on the front nine in the second round.

Likewise gathering momentum was Alison Lee who shot a 70 on Thursday, and Friday had four birdies through her first 12 holes. She grew up in Valencia and played at UCLA.

Lee had a son, Levi Todd Kidd, in April of last year and was back on the LPGA Tour within four months. She made her 2026 debut at the LET Saudi Ladies International in February and opened with a two-under 70 despite playing with rental clubs, as her regular set was stuck in Amsterdam.

Balancing a major championship and motherhood is no simple challenge.

“It’s been really tough trying to juggle everything,” she told reporters before the Open. “I feel like sometimes I’m drowning under water, but thankfully I have some great people and great help around me where I can get through it.”

She’s staying with her parents in Valencia so she won’t disrupt her son’s schedule, and has a backup room at Megan Khang’s nearby rental home for early tee times.

Recently, her baby had the kind of breakthrough every parent can appreciate.

“He’s sleeping a lot better,” she said. “Therefore, my life has been a lot easier. … I’ve been able to get a little more rest. I’ve been able to work out a little bit more and practice a little bit more.”

It is a bitterly disappointing way to exit the tournament for Sinner, whose favourite tag was enhanced further with defending champion and great rival Carlos Alcaraz missing with injury.

With 24-time Grand Slam-winner Novak Djokovic also nearing the end of his illustrious career, fitness was expected to be one of the biggest obstacles to Sinner’s bid for glory.

Paris has seen unseasonably hot weather, with temperatures topping 34C, and Sinner has struggled previously in extreme heat.

Sinner was also on a 30-match winning streak, having won five Masters 1000 titles in a row over the past three months on hard and clay courts.

He cramped badly in temperatures close to 40C at this year’s Australian Open, and admitted he “got lucky” when the heat rule was enforced in his third-round match against Eliot Spizzirri in Melbourne.

After opening his campaign against Clement Tabur in Tuesday’s cooler night session, Sinner was first on court against Cerundolo in a rare move by Roland Garros organisers.

The last time a men’s number one opened proceedings on Court Philippe Chatrier before the semi-final stage was 10 years ago, when Novak Djokovic beat Tomas Berdych in the quarter-finals.

Although Sinner seemed to benefit initially from the early start, the physical issues that have hampered his display in previous matches in extreme heat resurfaced.

Elsewhere, three-time former champion Novak Djokovic faced Frenchman Valentin Royer on Court Philippe Chatrier, which has a roof, and was on court for three hours and 44 minutes.

The 39-year-old Serb lost a tight third set on a tie-break but regrouped to win 6-3 6-2 6-7 (7-9) 6-3.

In his post-match press conference, Djokovic suggested scheduling matches at Grand Slams later in the evening could be “something to consider” as a potential alternative if extreme conditions are expected.

French Open organisers monitor the temperature through two wet bulb sensors – one on Chatrier and another on Court 14.

If the threshold is reached, a 10-minute break may be introduced after the second set of women’s matches and the third set of men’s matches.

If temperatures continue to rise, matches can be suspended until the heat drops.

No French Open match has ever been halted because of extreme heat.

Women’s 15th seed Marta Kostyuk said the conditions so far this week are not quite as bad as those she experienced when playing at the same venue for the Olympics in 2024, but added: “It’s still hot and it’s very dry. I always felt like I need to drink, I want to drink more and more. It was tough.”

On Monday, former finalist Casper Ruud said he felt he was “walking around like a zombie” and feared he had heat stroke after struggling with cramping in 33C temperatures.

One player who escaped the worst of the conditions on Wednesday was men’s second seed Alexander Zverev, who played in the night session when temperatures had dropped to about 18C.

A runner-up at Roland Garros in 2024, Zverev continued his bid for a maiden Grand Slam with a dominant display to beat Czech player Tomas Machac 6-4 6-2 6-2 in one hour and 48 minutes.
