The WTA clay swing is one of the most significant ranking reshuffles of the year. Stuttgart is already underway, with Madrid and Rome still to come before Roland Garros begins on May 18.
For players sitting just outside the top 20, the next five weeks represent a genuine opportunity to close the gap. The current top 20 cutoff sits at around 1,900 points, with Elise Mertens at No. 20 as the nearest benchmark. Here are five players ranked between No. 21 and No. 37 who have the form and the surface schedule to get there.
1. Leylah Fernandez — No. 25 | Canada | Age 23
Fernandez enters the clay swing as one of the most credible candidates on this list, but also one of the most frustrating to assess right now. She is ranked No. 25 and only around 300 points away from the top 20 cutoff — close enough that a semifinal run at Madrid alone could do it. The problem is that her 2026 season has been underwhelming so far.
Reports indicate she failed to get past the third round in the first nine tournaments she contested this year, a stretch of results that has kept her stationary in the rankings while others have moved around her.
The clay surface is where Fernandez has historically been at her most dangerous. She reached the quarterfinals at Roland Garros in 2022 and has a natural game for slower courts — the left-handed slice, the sharp angles, and the ability to construct points rather than simply trade from the baseline. If the clay swing triggers a return to form, the ranking gap is small enough that she could cross the line quickly.
She is currently in action at Stuttgart, where she beat Alex Eala in the first round and advances to face either Jasmine Paolini or a qualifier. A deep run this week combined with a solid Madrid showing would put her inside the top 20 before Rome even starts.
2. Emma Raducanu — No. 28 | Great Britain | Age 23
Raducanu is the name on this list with the most name recognition and, arguably, the most complex ranking story heading into the clay season. After years disrupted by injuries and inconsistency, she has shown genuine signs of stability in 2026.
She climbed to No. 23 following a Transylvania Open final run earlier in the season and has been building tournament-by-tournament since returning to consistent competition.
At No. 28, she needs to close roughly 400 points to crack the top 20. Clay is not her best surface — she has historically been more comfortable on hard courts, where she won her 2021 US Open title — but she has shown she can compete on the dirt and her next scheduled event is the Madrid Open, one of the biggest clay opportunities on the WTA calendar.
The key for Raducanu is staying healthy and stringing together matches rather than suffering the injury-related retirements that have defined so much of her recent career. If she can navigate Madrid and Rome without a setback, the top 20 is achievable. She is a player who, when fit and confident, is capable of beating anyone on the tour regardless of surface.
3. Marta Kostyuk — No. 27 | Ukraine | Age 23
Kostyuk has been one of the more consistent performers in the 20-to-30 range for much of 2026 and is currently climbing in the live rankings, sitting at No. 27 with 1,503 points after picking up 30 points this week. The Ukrainian plays an aggressive, flat-striking game that can cause problems on any surface, and she arrives at the clay swing with momentum behind her.
The gap to the top 20 from her current position is around 400 points. A deep Stuttgart run this week — she is still active in the draw — followed by a solid Madrid showing would get her there before Paris.
Kostyuk has shown this year she can compete consistently at the top level, and her physicality and mental resilience make her one of the harder players to break down in long clay-court matches.
She enters the clay swing without significant defending obligations, which means most of what she earns over the next month will be net positive movement. If she can avoid a run of early exits, the top 20 is a realistic target well before Roland Garros.
4. Emma Navarro — No. 26 | United States | Age 24
Navarro is another player sitting tantalizingly close to the line. At No. 26 in the live rankings, she needs roughly 350 to 400 points to break into the top 20 — achievable across just two or three good weeks on clay.
She has been one of the tour’s more consistent performers in 2026 despite slipping slightly in the live rankings this week, currently sitting at around 1,442 points.
The American plays a measured, high-percentage baseline game that adapts well to slower surfaces, and she has shown the ability to reach the later rounds of major events. Her challenge this clay season is the same challenge she has faced throughout 2026 — going deep enough in the big events to accumulate the points that push her into new ranking territory rather than hovering just outside it.
She is scheduled to compete in Stuttgart, where she is already in the draw, and will likely also enter Madrid and Rome. A semifinal at any one of those three events would be enough to push her over the threshold. The form is there — it is a question of timing.
5. Zheng Qinwen — No. 37 | China | Age 23
Zheng is the biggest mover target on this list — at No. 37 she needs to climb 17 places to reach the top 20, which is a steeper ask than the other four names here. But she is the most credible long-shot inclusion because of her demonstrated ceiling on clay and the fact that she has been significantly underranked relative to her actual level for several months.
A 2024 Olympic gold medallist and Grand Slam finalist, Zheng is a player whose ranking has been dragged down by a combination of injuries and a light tournament schedule rather than any drop in quality. She currently sits at 1,350 points after a difficult stretch that saw her slip from a higher position, but clay has historically been one of her stronger surfaces and she is fully capable of running deep at Madrid or Rome.
The points drop from her schedule means she enters the clay swing with room to gain rather than points to defend. If she plays a full clay calendar and returns to something close to her 2024 form, jumping from No. 37 to the top 20 before Paris is possible — but it would require her best tennis across multiple weeks, with no room for early exits at either Masters 1000 event.
The Bottom Line
The WTA top 20 is genuinely within reach for several players over the next five weeks. Fernandez and Navarro are the closest to the line and the most likely to cross it with just one strong week.
Raducanu and Kostyuk both have the level and the scheduling room to make a significant move if they stay healthy. Zheng is the longest shot but the highest upside — a player who, when motivated and fit on clay, can beat anyone in the draw.
By the time Roland Garros begins on May 18, at least two of these five names are likely to be sitting inside the world’s top 20.
