Leylah Fernandez has done it again. The Canadian defeated world No. 5 Mirra Andreeva 6-2, 7-5 at The Kallang on Friday, repeating her recent victory over the Russian in Toronto and sending the top seed out of the Singapore Tennis Open presented by BNP Paribas.

But if Fernandez’s win was the headline, the day had plenty more drama. Maja Chwalinska powered past Elise Mertens to reach the semifinals, Tatiana Prozorova’s extraordinary run ended in cruel fashion after a head injury forced her withdrawal from the semifinals, and Talia Gibson continued her rapid rise by defeating Maria Sakkari to reach her first WTA final.

For Fernandez, the victory over Andreeva was another demonstration of how effectively her aggressive game can disrupt the Russian’s rhythm on hard courts. The Canadian’s left-handed forehand repeatedly targeted Andreeva’s backhand, while her pace, angles and willingness to take the ball early left the fifth seed struggling to settle.

Fernandez, ranked No. 31, arrived in Singapore as a last-minute wild-card entrant after visa issues prevented her from competing in São Paulo. She has now turned that unexpected detour into a semifinal appearance.

“I knew coming into this match that Mirra was not going to give me the match easily. It was going to be a fight,” Fernandez said.

The 2021 US Open finalist was in control for much of the opening set, saving two break points at 1-1 before finding her rhythm. Andreeva never quite managed to disrupt the Canadian’s momentum, eventually losing the first set with a double fault.

The second set looked as though it might become a different story. Andreeva, a recent US Open quarterfinalist, fought back from 5-2 down to level at 5-5, suddenly putting Fernandez under pressure.

But the Canadian reset. “At 5-5, I was very happy that I used my training to calm myself down, going to my towel, doing my routines again, and, getting to 6-5, I knew it was going to be a battle to finish the match,” she said.

She closed it out without allowing the comeback to become another twist in the story.

The result gives Fernandez a 3-2 lead in her head-to-head record against Andreeva, with all three of her victories coming on hard courts. It also sends her into her first WTA 500 semifinal of the season.

Fernandez said the unexpected opportunity to play in Singapore had already become something special, particularly because of the atmosphere at The Kallang.

“We contacted Singapore, the tournament director and organizers, begging for a wildcard. And thankfully they accepted,” she said.

The crowd, she added, had been one of the highlights of the week.

“Every day I see fans; the stands are full, and they’re enjoying their time. I look at the screen during changeovers: They’re all smiling, playing the drums, playing the guitar. Just enjoying their time with their loved ones. It’s so beautiful to see.”

Fernandez will face Maja Chwalinska in Saturday’s semifinal after the Polish fifth seed produced another impressive performance, defeating Elise Mertens 6-2, 6-2.

It was Chwalinska’s third match of the week, while Mertens was playing her first after receiving a bye and then advancing following Barbora Krejcikova’s withdrawal. The difference in match rhythm showed as Chwalinska settled into the conditions and gradually took control.

The left-hander disrupted Mertens with changes of pace, higher balls and well-timed drop shots, while gradually finding greater depth and width on her groundstrokes.

The result marked Chwalinska’s first career Tour-level win over a Top 20 opponent and her first semifinal since her breakthrough run at Roland-Garros.

“I had some tough weeks, but the fact that I kept on working on myself, and I stayed patient, and just tried to push myself every single day, is paying off now,” Chwalinska said.

Her season has included both extraordinary highs and difficult stretches. After her run at the French Open, she rolled her ankle at Wimbledon and said it took time to regain confidence in her body and match rhythm.

“I feel like this year was just an emotional rollercoaster, really,” she said. “You need these losses, and you need these tough matches to build yourself. Even though it’s very sad sometimes and frustrating, I know that it’s just a part of the journey.”

Mertens, the defending champion from when the Singapore tournament was a WTA 250, acknowledged that she struggled to find her rhythm against an opponent who offered few easy points.

“She didn’t give me any free points,” Mertens said. “I really wanted to play aggressively, come to the net a little bit, but I made too many mistakes.”

The Belgian also revealed she had experienced some discomfort in her right shoulder, which affected her serving.

For Tatiana Prozorova, Friday began with another chapter in one of the tournament’s most remarkable stories.

The world No. 180 defeated Wang Xinyu 3-6, 7-5, 6-4 to reach the semifinals, completing another comeback in a week that had already seen her defeat Alexandra Eala.

But the celebration was short-lived.

After more than nine hours on court across three singles matches, Prozorova suffered a head injury towards the end of her doubles match later in the day. She subsequently withdrew from the singles semifinals, bringing an abrupt end to her breakthrough week.

Her victory over Wang had itself been another marathon.

Prozorova dropped the opening set as Wang’s pace and intensity caused problems, before building a 4-0 lead in the second. But just as she seemed to be pulling away, physical problems began to affect her, while Wang fought back from 5-2 down to level at 5-5.

Prozorova nevertheless found the composure to take the next two games and force a deciding set.

There, Wang saved five break points at 2-3, but Prozorova eventually found a way through. She won the final four games of the match, saving three break points while serving at 5-4 before closing out the victory on her third match point.

It was her first tour-level semifinal and her first time defeating two Top 50 opponents in succession.

After the match, Prozorova had every reason to celebrate. Instead, the injury suffered in doubles meant she would not be able to take her place in the last four.

It was an unfortunate conclusion to a week in which the 22-year-old had announced herself with a series of performances against much higher-ranked opponents.

The player who benefited from Prozorova’s withdrawal was Talia Gibson, but the Australian had already earned her place in the final by producing another breakthrough performance of her own.

Gibson defeated seventh seed Maria Sakkari in three sets, continuing the momentum that has carried her through the Singapore draw.

The 22-year-old was aggressive from the start, putting pressure on the former Top 10 player and refusing to let Sakkari establish the rhythm she had found in her earlier matches.

When Gibson dropped serve after taking an early 2-0 lead in the third set, she responded immediately. She moved ahead 4-1 and continued pushing until she secured the decisive break and closed out the match.

Her first WTA 500 match win came this week. Now she has reached her first WTA final.

“I played really well, to be honest. I think that’s some of the best tennis I’ve ever played,” Gibson said.

“I didn’t expect to get this far this week, so I think I just really enjoy the moment and enjoy being where I’m at.”

The result is another milestone in a year in which Gibson has broken into the Top 100 and repeatedly tested herself against higher-ranked opponents. She has now recorded 10 wins over Top 50 players this season.

For Gibson, the progress has come through patiently building her game.

“I think it’s just putting a lot of hours in on the court, being able to put some pieces together in my game, and trying to add a few different dimensions,” she said. “But at the same time, I think I’m just trying to get my strengths better as well.”

With Prozorova unable to continue, Gibson advances directly to the final.

That leaves Fernandez and Chwalinska to battle for the other place, setting up a semifinal between two left-handers whose contrasting styles should provide another very different test.

After a Friday filled with upsets, comebacks, breakthroughs and an unfortunate injury, the Singapore Tennis Open heads into its final weekend with another question waiting to be answered: can Fernandez’s high-speed game continue its run, or can Chwalinska disrupt the rhythm that has carried the Canadian past Andreeva?

The answer comes at The Kallang on Saturday.
